BI FLSensor (wired)
The Bitrek GPS fuel level sensor is a digital capacitive sensor used on diesel engines. Its accuracy depends on temperature and ranges from 99.1% to 99.3%.
This equipment detects the current fuel level in real time and records any changes during fuel charging or theft.
The device’s body is made of a material that is resistant to temperature extremes and mechanical stress. The sensor head is filled with a compound and features a measuring element made of aluminum, which can be between 750 and 3,000 mm long. The fuel sensor can be as short as 150 mm.

For years, Bitrek GPS has produced fuel level sensors for diesel engines. Here, we present the latest release of the wired FL level sensor. We constantly receive feedback from our dealers, and we have addressed the following points in this fuel sensor:
1. We improved the design and fitting method of the isolation cover in the sensor head. This cover secures the measuring probe.
As a result of these changes, we increased the durability of the sensor at the probe attachment point.
The sensor head became tighter. We resolved the issue of fuel under pressure infiltrating the sensor head and compromising its efficiency in vehicles with a faulty tank ventilation system.
2. The mechanical hardness of the measuring probe increased.
Consequently, the probe’s strength and resistance to mechanical pressure, which can occur when fuel moves in the tank, increased. Sensor readings have also become more stable.
3. The design was changed to increase the durability of the connection between the sensor head and the measuring probe.
4. The measuring probe’s connection type changed. As a result, the output SignalGND pin (brown wire) is now galvanically isolated from the outer tube of the measuring probe.
5. The form and fastening method of the protective cap at the end of the measuring probe have changed.
As a result:
Slipping of the cap from the probe is excluded.
The cap is also excluded from the sensor’s measuring circuit.
We also have other features and hardware extensions for this device. Using Bitrek’s external modules, we can design a unique, applicable control system for any vehicle type.
