SUP-RD902 Radar Type Level Transmitter

Intelligent radar type level meter is suitable for non-contact continuous level measurement of liquids, slurries and granular materials, and is suitable for occasions with large temperature and pressure variations; the presence of inert gases and volatile


Radar type level meters emit very short microwave pulses of very low energy that are transmitted and received through an antenna system. The radar wave travels at the speed of light. The running time can be converted into a level signal by means of electronic components. A special time-stretching method ensures stable and accurate measurements in a very short time. Even in the case of complex conditions and spurious echoes, the latest microprocessor technology and commissioning software allow accurate analysis of the level echoes.

The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes this signal and identifies the echo generated by the micro pulse on the material surface. The correct identification of the echo signal is done by intelligent software with an accuracy of millimeters. The distance D from the material surface is proportional to the time travel T of the pulse.
  where C is the speed of light
  Since the distance E from the empty tank is known, the level L is L=E-D

Set by inputting the empty tank height E (=zero), full tank height F (=full scale) and some application parameters which will automatically adapt the instrument to the measurement environment. Corresponds to 4-20mA output.

Installation Guide

Radar Type Level Transmitter factory Radar Type Level Transmitter for sale in bulk wholesale Radar Type Level Transmitter customized

Be installed in the diameter of the 1/4 or 1/6.   

Note: The minimum distance from the tank 

wall should be 200mm.

Note:  ① datum 

②The container center or axis of symmetry

The top conical tank level, can be installed at 

the top of the tank is intermediate, can guarantee 

the measurement to the conical bottom

 A feed antenna to the vertical alignment surface.  

 If the surface is rough, stack angle must be used 

 to adjust the angle of cardan flange of the antenna 

 to the alignment surface. 

  (Due to the solid surface tilt will cause the echo attenuation, even Loss of signal.)
