LR200 Series - Low frequency
Radar technology is put into use for detection of level in continuous level measurement applications. A radar level detector basically includes:A transmitter with an inbuilt solid-state oscillator.
A radar antenna.
A receiver along with a signal processor and an operator interface.
The operation of FR100 involves sending microwave beams emitted by a sensor to the surface of medium in a tank. The electromagnetic waves after hitting the fluids surface returns back to the sensor which is mounted at the top of the tank or vessel. The time taken by the signal to return back i.e. time of flight (TOF) is then determined to measure the level of medium in the tank
