Level measurement with ultrasonic echo beam.

  • Tank sizes up to 100,000 Litres
  • Suitable for all kind of liquids.(Exept kind of hazardous liquids)
  • 3 stage expanded product portfolio.
  • Even with GSM and wireless data transfer.



Heating oil tanks, water tanks, rainwater tanks, waste oil tanks.

The instruments of the LC series measure the runtime of ultrasound pulses in order to detect the level of tank content. All determined values are displayed on the instrument display. All current tank shapes such as cubic, cylindrical, lying or standing cylindrical tank shape are supported. The tank capacity is calculated from the input parameters and measured distances from the sensor to  liquid level.

The daily consumptionand storage of contents in days can also be displayed.


LC products have been developed in cooperation with Swiss company ESI and brought  through by own marketing distribution.

LC units are primarily intended to replace the equipment with modern technology, the conventional mechanical fuel gauges. Care was taken to a high accuracy and appropriate evaluation criteria. The LC products have a  dip stick accuracy . The equipment was designed to measure once per day. In addition, the devices are designed in a modular system, so that we now have a large product portfolio.

  • The serial numbers 100 are assigned to the smaller tanks up to 10,000 liters.
  • The series with the number 200 are equipped for larger tanks up to 100,000 liters. LC 200  have GSM modem with which it is possible to send the measured data via GSM.
