Fuel level sensors

Designed to accurately measure the fuel level in the tanks and the tanks of vehicles. The sensor can be used as part of control systems for fuel consumption (control of spouts and refills) and satellite systems GPS monitoring of transport.

Sensor probe when immersed in fuel functions as a variable capacitor whose capacitance is linearly dependent on the level of its fuel filling.

The measuring head of the sensor performs a linear transformation capacitance probe into digital code level of the fuel processing the digital data obtained by averaging measurement results, the measurement of the temperature of the fuel tank and delivery of the data in a standardized protocol EDE via RS-485 or RS-232, or the analog signal (the level only fuel), depending on the model.

These fuel level may be granted in the form of 10-i, 12-or 16-bit value, the temperature data - as 8-bit values​​. 

To determine the volume of controlled fuel must be performed calibration procedure of the fuel tank, in which we establish the relationship between the volume of consumption and the level of measured sensor (code level).
