• GPSM SensorThe power of precision.

    Capacitive fuel level sensor

    Our new fuel level sensor (FLS-series) is specially designed for precision measurements.
    It contains accelerometer that helps recognize movement of the vehicle. This patented technology provides continuous stable output of tank contents during movement regardless of vibration of the fuel tank.

  • Fuel Level IndicatorCompatible with all GPSM sensors

  • GPSM Fleet management solution.

    A powerful, user-friendly GPS/Glonass tracking solution.


    Easy and effective way to keep your fleet under control and encrease cost efficiency. Save up to 25% of the monthly fuel costs.

Electrical isolation

Inbuild galvanic isolation helps to reduce system electronic noise. It offers very high accuracy of the measurements. From now, no need in additional voltage stabilizers and filters!


Our GPSM Sensor is an interfare between hardware and software. It has inbuild accelerometer that provides info about level of vibration of the fuel tank that helps calculate precise fuel level.

2-Year Warranty*!

It is definitely longer than 1.

We're so con?dent in the quality of our products, we guarantee it!
We make significant efforts to continually improve our products and services.


Why our fuel gauge is better than others?

GPSM Sensor is an innovative Capacitive Fuel Level Sensor used at a vehicles. It has advenced accelerometer sensor bouild in. As you can see from the chart below, the stability of the output data from the fuel gauge are incredebly higher and more stable comparing to usual fuel level sensors.

Temperature measurements

GPSM Sensor is an optimal choice for conditions identified by changes in temperature. Temperature indication is provided to enable precise measurement in hot and cold conditions.The GSPM sensor provides temperature, accelerometer data, and fuel level measurements via the RS-485 or RS-232. The temperature measurement is performed using a thermistor contained in the sensor housing.

How it works?

Fuel level measurement depends on temperature of the fuel. Therefore GPSM Sensor use temperature data to calculate fuel level precisely. This calculation is based on a strapping table programmed inside the sensor.



GPSM sensor is designed for any type of fuel such as Gasoline, Unleaded, LRP, Jet Fuel, Avgas.

Complete protection against dust and water

All sensors passed tests: immersion at depth of at least 1 m measured at bottom of device, and at least 15 cm measured at top of device.

Temperature conditions

GPSM sensor with fully integrated electronics can operate in a wide range of temperatures:
from -45 to +125 °C.


  • RS-485 and RS-232 interface +

    GPSM Sensors can use RS-232 or RS-485 digital output (communication interface). Such interfaces send noise-free data.
  • Analogue Output +

    GPSM Sensors are available in with wide range analogue output (0-30V). Moreover, it is User-programable. It means that you can change it according to your needs.
  • Frequency interface +

    GPSM Sensors with Frequency interface transmit fuel data as a frequency signal (500-1500 Hz).
  • Probe Length Available +

    Lengh of all sensors can be customized according customer's request. Standart sizes: - 70 cm; - 140 cm; - 250 cm; - 350 cm; - 550 cm;
