Bamo PILOTREK Radar Level Measurement

Bamo PILOTREK Radar Level Measurement is a radar level transmitter without contact with the liquid, with protected electronic module integrated in the housing. Compact, this device powered by the 4-20 mA loop is distinguished by its reliability and accuracy. Located above the liquid surface, it provides an analogue signal proportional to the level of the liquid.

The measurement is not affected by changes of operating temperature and pressure. Easy settings through only 4 keys. For complete programming, the display module SAP 300 provides access to all parameters. The radar operates at a frequency of 25 GHz (K band). Compared to radars operating at low frequency (5-12 GHz), the antenna size, the dead zone and the measurement angle are reduced.

Bamo PILOTREK Radar Level Measurement Features

  • Measuring range: 0.2 to 23 m
  • Without contact with the fluid
  • 4-20 mA loop power supply
  • IP 67 compact housing
  • Option: Display/ programming module


PILOTREK is an accurate level transmitter of liquids, slurries, emulsions and other chemicals in many fields of application such as: food, energy, pharmaceutical, chemical industries and even in shipbuilding. PILOTREK provides a contact-free measurement for those substances which create vapors and is convenient as well as for vacuum applications.
