Maintenance of the remote fuel monitoring system can be done easily. Even with strong circuit protection and rigid design, the fuel level sensor sometimes fails. It can be vandalism issue or careless damage to the sensor. Conventional fuel level sensors do not have a modular design and are assembled with electrodes. When replacing the level sensor, the calibration procedure of the tank must be repeated, since the electrodes have individual features. Their characteristic is superimposed on the calibration characteristic of the fuel tank. For Eurosens Dominator sensors, the electrodes are easily detached from the housing and can be used further with a new electronic module (the “head” of the sensor). Let’s see what kind of error in the level measurement brings the replacement of the electronic module. We take 10 electronic modules Eurosens Dominator RS from the stock, connect to the configuration software and write down the values ​​of the detector – the internal value of the “level”. Then, to each of the modules we connect the same electrode Electrode 1 with a length of 700 mm. Result you can see in the table below.

Value of detector after full immersion Dominator RS in the fuel : 10800 Conclusions: Maximum deviation of the detector values in a batch of 10 pieces: 22 units. Range of detector changes from full to empty: 4201 units The maximum additional error when replacing the electronic module: 22/4201 * 100% = 0.52% That is less than temperature fluctuations of volume of fuel in a tank. To be sure that calibration is not required, we recommend checking the values of the empty tank detector for the new electronic module with the old value, which is saved in the calibration file during initial installation.
