You already have defined the pins of the flow sensors. Gni|I'#k W, W0Ku XfZ0)SS;ycB5q;9Au>SrWdDibO_clSC`n$c5Hqy6UJr\ I would suggest using clearer names: flow_out meaning leaving the tank, flow_in coming back into the tank. NOTE: Some boards have GRN where my boards have GND. 
Infra Red sketch "not declared in this scope", Problem with a DHT11 Temperature & Humidity sensor. endobj (value is stored after 15 seconds with no flow). before it is reset. The difference is with a diesel motor the fuel pump sucks more fuel than it burns from the fuel tank and simply returns the excess to the fuel tank. Always make sure everything works as it should. <> Here comes a different principle, than your firstly intended way: I would let the sensors count in their own ISR and own variables and only calculate the difference to display it. The actual flow-modules are the same module as the on in Jetimodels flow sensors. The variable pulseCount is only 8-bits. rev2022.7.29.42699. In fact you don't have to do that.
After this go to next screen by pressing Right. I have a sketch that already works to print L/m and total L. For one sensor on PIN D2. If you made an error press left and right to reset to zero and start over. Do not use faulty devices. Which I don't really even remotely understand. Set your sensor so you can pass one liter (1000ml) of fuel through it. xn@Ea `~ 468). NOTE: When installing and using the sensor note the flow direction! Send a small donation to help keep RC-Thoughts ad-free and Tero with enough coffee he needs! This comment is wrong. First let's look at the prerequisites, that are needed for the two flow sensors.

Jetibox-reset is also of course still available. Meanwhile, the sensor has liner analog voltage output, easy to use. miscounting whenever an interrupt fires after pulseCount is read but actual flow exceeds this rate, then, as pointed out in chrisl's answer, as is they both just add to a single total. So my plan is to have 2 flow sensors (Yf-s201), and subtract the out put of one from the other and print the difference. When you are in calibration screen you can also enter the calibration value manually: As picture says, press down to add 1000, up to add 100 and up & down to add 10 to calibration value. (Example is further below). and benefit from the fact that accesses to 8-bit values are atomic. Press Down to change between Yes and No. As its custom with DIY-sensors, dive into teh interwebs and get some parts: NOTE: Make sure you get the 5V 16Mhz version of Arduino Mini Pro! In first start of sensor or if sensor is reset to defaults it shows calibration value of zero. Easiest method is RC-Thoughts Firmware Uploader, Real Flight 7.5 + Jeti DS-16 + Rsat2 = True, Arduino Pro Mini 5V 16Mhz (Or equivalent) Example link to Ebay, Consumption possible to reset via Jetibox, Option to store consumption and remaining percentage between flight and reset with digital output, Possibility to use any BT Bio Tech flow-sensor with pulse output and 5VDC operating current, Arduino 5 -> Receiver output defined as Deigital Output, 1.1 Added tank size setting and fuel remaining percentage, 1.2 Fixed fuel remaining display bug and negative percentage, 1.3 Redone menus and calibration, allows BT Bio Tech flow-modules with various pulse-counts, 1.4 Added possibility store consumption and remaining-% to memory between flights, 1.5 Added possibility for manual setting of calibration-value. JBKj "`"[@u|5!k3.
You also need to configure a Digital Output from receiver to Arduinos pin 5. I guess you have problems in designing the code, so I try to walk you trough. 
The more accurate you measure the one liter the more accurate the sensor will be in use. With that you can then calculate the total net flow and the fill level. You should never use LUA-apps for operation-critical functions. if you want to reset fuel-sensor to defaults (zero-size tank, uncalibrated) press Up and Down at the same time, sensor resets and blinks Arduino led once. Youre seeing this ad based on the products relevance to your search query. Pumping speed has no difference as long as its around the sensors capabilities. Heres a screenshot of values on main screen: Values in itself are simple. Upload the codes to UNO, then open the serial monitor to check the gas flow.

Standard-state: 20 gas temperature and 101.325 kPa gas pressure). If you fill the data into this table, you will get a fitting curve. If you want to re-calibrate press left & right to reset calibration-value to zero. As default tank is at 0ml in size. calls to millis() will return the same value within one iteration. Does China receive billions of dollars of foreign aid and special WTO status for being a "developing country"? A fuel monitoring tool that can monitor and send warnings to the excavators owner if there is any fuel access into the excavator fuel tank during the rest time of the excavATOR. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. If enabled sensor will store consumed fule-value and remaining percentage after flight. .ino (Named RCT-FuelSensor) file from my Github, . endstream I suggest to put the Arduino inside shrink-wrap for protection in the final version. Prototype module is from Conrad and is the 15-800ml/m version. You are also defining the number of the corresponding interrupts. I have defined another sensor on PIN D3. First: When handling interrupt data in the main code, you want to absolutely minimize the time spend with the interrupts deactivated (since in that time you might miss pulses and thus introduce errors). It does not disable interrupts !a9GbKaDFxyg|~P TKto;d|yvgG} My first road block is to print them individually. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. As usual, go to Main Menu -> Timers/Sensors -> Sensors/Logging Setup and do a sensor search. Your code currently does not use the second flow sensor.

With Arduino and .ino you need to use the libraries included in Github repository. If you need to reset it without powering down the sensor it can be done in the next screen to the right. Could really not be more simple and useful than that :). Connect and share knowledge within a single location that is structured and easy to search. The Biotech-manufactured sensor Jetimodel uses has a reported range of 15 to 800ml/m or 50 to 3000ml/m depending on model you choose. the traditional fuel gauge system and the smart. You will find a new sensor with three values: After that you can get fuel-values to your main screen: After connecting sensor to receiver head on to Jetibox and MX-screen, then down and you are in the Fuel Sensor: Pressing right takes you to Jetibox-screen with values in real-time: Consumption is reset on sensor power-cycle. Next up is the calibration, we need to teach the sensor the amount of pulses it gives when one liter of fuel is used.
For that we need to define our 2 ISRs: The count variables of course need to be defined (globally at the top of the sketch): Now we have left the code in loop(), which calculates flowrate, fill level and such and displays them. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. Now-a-days all fuel bunks having types of digital displays unit in order to display the value of fuel adding to the vehicle. There is therefore no guarantee that the various C/~iO7/_$:)j2_|{[M^^EbqqdZVf- I have tried to just copy bits of code and add a "2" but I really don't have any programing knowledge so I am just stabbing in the dark. Press Down to reset, press right to move on. After calibration is done and all settings are saved there is a *-sign after the calibration value, here is an example: After you are done press right, here you need to decide if you will use sensors reset-function. Story about 3 humans stranded on alien planet/ruins, solve riddles, rescue aliens from astral form? So lets make one. Is the theory of a partial order bi-interpretable with the theory of a pre-order? Im a car-mechanic by training, not a programmer-geek :), Is to have fun building and using, this will not bankrupt you in any way :).
You get the fuel flow meaning how fast fuel is consumed and you get the total amount of fuel used.
increments millis(). This means you do not need to ever disable interrupts: then you compute the flow rate from pulseCountDifference.

Note: You might wanna change the variable type for the counters to unsigned int to get a greater margin, before they overflow, since that would mean incorrect results and it doesn't hurt you to use it.
Thanks for contributing an answer to Arduino Stack Exchange! Fuel Sensor works with any 5V flow-sensor! Go to Function Assignment and create new function, here I named it as FuelReset, assign a control (switch for example) for it: After this go to Servo Assignment and define a channel for the function, here its on channel 10: Next power up the model, go to Device Explorer and Define one of your receivers to Digital Output in Pin Config, here I used OutputPin 4: Last thing you need to do is to point the FuelReset-channel to OutputPin 4, so go to Device Explorer and outputs, define the FuelReset to OutputPin 4: Make sure the channel-value is 100% and goes to -100% on reset. Different flow-sensor modules available I could find online: Both flow-modules are the corrosive fluid-version so they will take any fuel you give them without damage. I have worked through your suggestions, and I have got as far as: void flowOutPulseCounter() { flowOutPulseCount++; } void flowInPulseCounter() { flowInPulseCount++; } But I get "a function-definition is not allowed here before '{' token" error. Get F1031V Air Flow Sensor from DFRobot Store or DFRobot Distributor. Connection are simple and if you have built any DIY-sensors before they are familiar: You also need the connection to Jeti receiver: Optionally you can also use receivers Digital Output to reset values with Digital Output, connection is one wire. Safe to ride aluminium bike with big toptube dent? Transducers are being used extensively for measurement as well as control instrumentation in virtually all scintific and industrial fields. Here is my 15-800ml sensor as example after one liter fuel has passed through. So we are left with the pin definition. })ir >N%HFSZa#r4tl@ Yqfx-gvFig Pay attention to the polarity of power in case of burning the internal circuit. As chrisl already provided a very good answer, I am just adding some You can easily get the number of the interrupt through the function digitalPinToInterrupt(pin). d-uWi]AJtc8v(m There are many sensor based techniques available in the market to measure the liquid level and gives you a close idea of quantity of the liquid, however can provide you an exact approximation of, ISSN: 2278 1323 All Rights Reserved 2014 IJARCET 40 Abstract The paper describes the existing fuel gauge techniques being used in automobiles i.e. endobj ie there are 2 hoses from the fuel tank, one to the motor, and one back to the tank. After you are done press right to reset/save-screen. This paper discusses how this transducer is used for measuring fuel in liters, calculating mileage for every liter of fuel, reducing shaking error, and displaying fuel readings in rough indication format. Go and get the suitable.hex or.ino (Named RCT-FuelSensor) file from my Github here. It can be used in applications like ventilator, air purifiers, etc. It may be noted that this can be simplified to.

Meanwhile, the sensor has liner analog voltage output, easy to use. miscounting whenever an interrupt fires after pulseCount is read but actual flow exceeds this rate, then, as pointed out in chrisl's answer, as is they both just add to a single total. So my plan is to have 2 flow sensors (Yf-s201), and subtract the out put of one from the other and print the difference. When you are in calibration screen you can also enter the calibration value manually: As picture says, press down to add 1000, up to add 100 and up & down to add 10 to calibration value. (Example is further below). and benefit from the fact that accesses to 8-bit values are atomic. Press Down to change between Yes and No. As its custom with DIY-sensors, dive into teh interwebs and get some parts: NOTE: Make sure you get the 5V 16Mhz version of Arduino Mini Pro! In first start of sensor or if sensor is reset to defaults it shows calibration value of zero. Easiest method is RC-Thoughts Firmware Uploader, Real Flight 7.5 + Jeti DS-16 + Rsat2 = True, Arduino Pro Mini 5V 16Mhz (Or equivalent) Example link to Ebay, Consumption possible to reset via Jetibox, Option to store consumption and remaining percentage between flight and reset with digital output, Possibility to use any BT Bio Tech flow-sensor with pulse output and 5VDC operating current, Arduino 5 -> Receiver output defined as Deigital Output, 1.1 Added tank size setting and fuel remaining percentage, 1.2 Fixed fuel remaining display bug and negative percentage, 1.3 Redone menus and calibration, allows BT Bio Tech flow-modules with various pulse-counts, 1.4 Added possibility store consumption and remaining-% to memory between flights, 1.5 Added possibility for manual setting of calibration-value.

You also need to configure a Digital Output from receiver to Arduinos pin 5. I guess you have problems in designing the code, so I try to walk you trough. The more accurate you measure the one liter the more accurate the sensor will be in use. With that you can then calculate the total net flow and the fill level. You should never use LUA-apps for operation-critical functions. if you want to reset fuel-sensor to defaults (zero-size tank, uncalibrated) press Up and Down at the same time, sensor resets and blinks Arduino led once. Youre seeing this ad based on the products relevance to your search query. Pumping speed has no difference as long as its around the sensors capabilities. Heres a screenshot of values on main screen: Values in itself are simple. Upload the codes to UNO, then open the serial monitor to check the gas flow.

To learn more, see our tips on writing great answers. When you have pumped exactly one liter through stop and you should see the amount of pulses your flow-sensor gives with one liter. "Hardy-ian", "Hard-ian", "Hard-enian". The difference between what went to the motor and what went back to the tank is how much fuel the motor burned. that this value cannot be exceeded, then you can keep an 8-bit counter, xZYOK/?1k_H`3I4~hx6;qCH2X:K:[Y20S2=sI\;hF B0
JTLjTbA02$9&E($&0 RfLYc F1031V Mass Air Flow Sensor adopts thermodynamic principle to detect flow rate of gas medium in the flow channel, with high precision and good repeatability. I have a water flow sketch I use for my freshwater consumption. I would like to adapt it to use for diesel fuel consumption. 1 0 obj I don't understand how to call upon the value the code has calculated. How do I make another action repeat inside a loop? In this sensor you can use any flow-sensor from BT Bio Tech as long as it has pulse-output and has 5VDC operating voltage.
disables only an external interrupt.
Standard-state: 20 gas temperature and 101.325 kPa gas pressure). If you fill the data into this table, you will get a fitting curve. If you want to re-calibrate press left & right to reset calibration-value to zero. As default tank is at 0ml in size. calls to millis() will return the same value within one iteration. Does China receive billions of dollars of foreign aid and special WTO status for being a "developing country"? A fuel monitoring tool that can monitor and send warnings to the excavators owner if there is any fuel access into the excavator fuel tank during the rest time of the excavATOR. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. If enabled sensor will store consumed fule-value and remaining percentage after flight. .ino (Named RCT-FuelSensor) file from my Github, . endstream I suggest to put the Arduino inside shrink-wrap for protection in the final version. Prototype module is from Conrad and is the 15-800ml/m version. You are also defining the number of the corresponding interrupts. I have defined another sensor on PIN D3. First: When handling interrupt data in the main code, you want to absolutely minimize the time spend with the interrupts deactivated (since in that time you might miss pulses and thus introduce errors). It does not disable interrupts !a9GbKaDFxyg|~P TKto;d|yvgG} My first road block is to print them individually. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. As usual, go to Main Menu -> Timers/Sensors -> Sensors/Logging Setup and do a sensor search. Your code currently does not use the second flow sensor.

Support for surrogacy from pro-choice groups, "Negating" a sentence (by adding, perhaps, "no" or "don't") gives the same meaning. rate gets above 33.7L/min. <> But thats DIY, and maybe we can make that for the price-difference :).
Dirt in the gas flow medium will reduce the sensor's service life, so it is recommended to install a 5-micron precision filter at the sensor inlet. K{Re/-tL~.!5cRCVqkSBdYrqed]MJ0UZ2IBR Bz m z6;q~w(1}o[59 N i-|j / *X'A"C Then in setup() we need to initiate the pins. It is forbidden to use the sensor in the environment with strong corrosive gas, toxic gas or explosive gas. overflows of pulseCount are harmless, as the difference If you are using a fuel-powered model you might be interested in fuel consumption. NOTE: please change the appropriate reference voltage according to mainboard. K(b:\jLko#x=eK"*2da|02]/}h _}2wl[L!w)O9\BY)/,3J`(!2nQ+w40Fk|QCp}c7Z. With Arduino and .ino you need to use the libraries included in Github repository. If you need to reset it without powering down the sensor it can be done in the next screen to the right. Could really not be more simple and useful than that :). Connect and share knowledge within a single location that is structured and easy to search. The Biotech-manufactured sensor Jetimodel uses has a reported range of 15 to 800ml/m or 50 to 3000ml/m depending on model you choose. the traditional fuel gauge system and the smart. You will find a new sensor with three values: After that you can get fuel-values to your main screen: After connecting sensor to receiver head on to Jetibox and MX-screen, then down and you are in the Fuel Sensor: Pressing right takes you to Jetibox-screen with values in real-time: Consumption is reset on sensor power-cycle. Next up is the calibration, we need to teach the sensor the amount of pulses it gives when one liter of fuel is used.
For that we need to define our 2 ISRs: The count variables of course need to be defined (globally at the top of the sketch): Now we have left the code in loop(), which calculates flowrate, fill level and such and displays them. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. Now-a-days all fuel bunks having types of digital displays unit in order to display the value of fuel adding to the vehicle. There is therefore no guarantee that the various C/~iO7/_$:)j2_|{[M^^EbqqdZVf- I have tried to just copy bits of code and add a "2" but I really don't have any programing knowledge so I am just stabbing in the dark. Press Down to reset, press right to move on. After calibration is done and all settings are saved there is a *-sign after the calibration value, here is an example: After you are done press right, here you need to decide if you will use sensors reset-function. Story about 3 humans stranded on alien planet/ruins, solve riddles, rescue aliens from astral form? So lets make one. Is the theory of a partial order bi-interpretable with the theory of a pre-order? Im a car-mechanic by training, not a programmer-geek :), Is to have fun building and using, this will not bankrupt you in any way :).
You get the fuel flow meaning how fast fuel is consumed and you get the total amount of fuel used.
increments millis(). This means you do not need to ever disable interrupts: then you compute the flow rate from pulseCountDifference.

Note: You might wanna change the variable type for the counters to unsigned int to get a greater margin, before they overflow, since that would mean incorrect results and it doesn't hurt you to use it.
Thanks for contributing an answer to Arduino Stack Exchange! Fuel Sensor works with any 5V flow-sensor! Go to Function Assignment and create new function, here I named it as FuelReset, assign a control (switch for example) for it: After this go to Servo Assignment and define a channel for the function, here its on channel 10: Next power up the model, go to Device Explorer and Define one of your receivers to Digital Output in Pin Config, here I used OutputPin 4: Last thing you need to do is to point the FuelReset-channel to OutputPin 4, so go to Device Explorer and outputs, define the FuelReset to OutputPin 4: Make sure the channel-value is 100% and goes to -100% on reset. Different flow-sensor modules available I could find online: Both flow-modules are the corrosive fluid-version so they will take any fuel you give them without damage. I have worked through your suggestions, and I have got as far as: void flowOutPulseCounter() { flowOutPulseCount++; } void flowInPulseCounter() { flowInPulseCount++; } But I get "a function-definition is not allowed here before '{' token" error. Get F1031V Air Flow Sensor from DFRobot Store or DFRobot Distributor. Connection are simple and if you have built any DIY-sensors before they are familiar: You also need the connection to Jeti receiver: Optionally you can also use receivers Digital Output to reset values with Digital Output, connection is one wire. Safe to ride aluminium bike with big toptube dent? Transducers are being used extensively for measurement as well as control instrumentation in virtually all scintific and industrial fields. Here is my 15-800ml sensor as example after one liter fuel has passed through. So we are left with the pin definition. })ir >N%HFSZa#r4tl@ Yqfx-gvFig Pay attention to the polarity of power in case of burning the internal circuit. As chrisl already provided a very good answer, I am just adding some You can easily get the number of the interrupt through the function digitalPinToInterrupt(pin). d-uWi]AJtc8v(m There are many sensor based techniques available in the market to measure the liquid level and gives you a close idea of quantity of the liquid, however can provide you an exact approximation of, ISSN: 2278 1323 All Rights Reserved 2014 IJARCET 40 Abstract The paper describes the existing fuel gauge techniques being used in automobiles i.e. endobj ie there are 2 hoses from the fuel tank, one to the motor, and one back to the tank. After you are done press right to reset/save-screen. This paper discusses how this transducer is used for measuring fuel in liters, calculating mileage for every liter of fuel, reducing shaking error, and displaying fuel readings in rough indication format. Go and get the suitable.hex or.ino (Named RCT-FuelSensor) file from my Github here. It can be used in applications like ventilator, air purifiers, etc. It may be noted that this can be simplified to.
