How to calibrate CAP10 Fuel Level Sensor?
Question: How to calibrate CAP10 Fuel Level Sensor?
Answer: Please follow these steps
Daviteq Fuel Level Sensor was designed to minimize the error of installation, therefore it is not required to use any special tool for calibration, thanks to its smart Firmware!
After cutting, leave the sensor in dry condition, apply the Power in 30s minimum, and it will automatically recognize the Zero and Span value.
** Just in case, if the technician forgot to do this step, just take the sensor out of the fuel tank, turn OFF the sensor, leave it dry for a while then do the above step.
In the manual, you can find these instructions in steps 6 and 7.
What happens next after self-calibration?
- The sensor will give an output value from 0..5 in dry conditions (no fuel level)
- The sensor will give an output value from 985..1015* when the fuel is filled up to the upper vent hole.
* This value is applied for standard Diesel in Vietnam. If using another diesel, the value may be a different value. For example, Malaysian diesel will give an output value from 1080 .. 1110
From that, you can map the level to volume by 02 methods:
- Fill fuel to the tank in multiple steps; each step is 10 liters or 20 liters ==> record the level (%) and volume (steps) ==> and make a look-up table on the server to convert from level to volume.
- OR, if the tank shape is simple (rectangular or horizontal cylindrical) ==> you can measure the dimensions ==> use the formula to calculate the level to volume, and put it on your server. This method may have lower accuracy, but it is a cost-effective solution!
