Radar Level Transmitter

$ 1,315.35$ 1,592.85

Radar level transmitters are used for non-contact level measurement of liquids and bulk solids.   They measure all kinds of liquids, even under high pressure and extreme temperatures.   They can be used in simple as well as in aggressive liquids and are suitable for applications with stringent hygiene requirements.   The radar level transmitters measure light as well as heavy bulk solids with absolute reliability, even in the presence of dust and noise, and without being affected by buildup or condensation.

Radar level transmitters can measure in:

  • Liquids
  • Pastes
  • Powders
  • Bulk solids


Radar Level Transmitter







Radar Level transmitter provides accurate level measurements of liquids, solids, and slurries.  Radar Level transmitters are non-contact level measurement


How does radar level transmitter work?


With a radar level transmitter, microwaves are transmitted by the antenna system of the radar sensor to the measured product, reflected by the product surface, and received back by the antenna system.  The time from emission to reception of the signals is proportional to the level in the vessel.

What are the advantages?


Non-contact level measurement with radar is characterized by particularly high measurement accuracy.  The measurement is affected neither by fluctuating product properties nor by changing process conditions such as temperature, pressure, or intense dust generation.  Above all, user-friendly adjustment without vessel filling and emptying save time.

Non-contacting radar technology is the choice for tanks with moving objects and temperatures and pressures.  It is also unaffected by media density.  As a result, all of this significantly reduces maintenance needs.

Non-contacting radar is based on microwave technology which detects only surfaces that reflect energy.  Hence, in a measurement situation, temperature variations, dust or pressure changes do not affect accuracy. 

The device measures the time it takes for microwaves to leave the transmitter, reflect on the media, and return back.  In all cases, due to that, the level is directly proportional to the time of flight.

For that reason, with non-contacting technology, it is also possible to calculate volume and mass.

With built-in diagnostics, no need for calibration, and the ability to detect even the smallest of changes, our devices improve process optimization.


How a radar level transmitter converts a signal to a measurement


The integrated electronics converts the measured value into an analog or digital signal for transmission.  This signal can be used for an external display or a process control system.  Additional components for Ex separation, overvoltage protection, or wireless communication enable a wide range of applications
