Simple installation


Explosion-proof protection


The sensors of Epsilon series provide the measurement of fuel level in a vehicle tank with reduced error no more than 1-2%. This accuracy allows registering the minimal fuel charge and drain volume about 5-10 litres for trucks and 10-20 litres for heavy machinery. Compared with the standard resistive type fuel sensors the capacitive sensors are completely electronically operated and bear no moving parts, ensuring low inaccuracy, stability and reliability in operation.

Simple Installation

All sensors of Epsilon series have a modular design, e.g. the measuring head is mounted and dismantled independently of the fuel probe, which allows easy and quick change, if necessary, the measuring head without recalibration of the tank. This design allows simple installation even in not easily accessible places. 

Operation Safety

All Epsilon sensors are installed partly inside the fuel tank  and partly in close proximity to the fuel tank, e.g.  in hazardous explosive environment. So all Epsilon sensors have approved intrinsic safety barriers (of 1Ex protection type for Epsilon ES and EN, and 0Ex for Epsilon EZ). The explosion-proof protection of Epsilon sensors is confirmed by appropriate national and EU certificates.


Customer Support

Our support service operates for technical assistance of the customers all over the world. Experienced professionals will assist and advise in installation, configuration and operation of fuel level sensors Epsilon.

for liquids (LPG, water, chemicals) in barrels

The sensor is used for continuous non-invasive, digital, automatic measurement of LPG level and other liquids such as water, chemicals.

Sigma ULB measures the level mainly in aboveground stationary cylindrical metal tanks from 10 cm up to 4 meters depending of the liquid density.

The sensor has measurement error from 5% up to 1 mm depending on the model. Can be installed in the 0 explosive zone.

The sensor is a device that consists of one or two ultrasonic emitters / meters connected to a signal converter.

The converter is connected to intrinsically safe unit. The barrier is not included in the installation set and supplied as a separate, independent product.

Sigma ULB has RS 232, RS 485 output and can be easily connected to GPS tracker, PC, notebook, smartphone or digital indicator
