Radar has been part of the level measurement market for more than thirty years. The early designs used in tank gauging were heavy, expensive, power-hungry and complex. Advancements in radar circuitry have evolved the modern radar transmitter so that now it is light, inexpensive, loop-powered and easy to use. The R82 is the logical extension of that evolution.
Measurement Principle:
The R82 Radar transmitter is based on pulse burst radar technology with equivalent time sampling circuitry. Short bursts of 26GHz microwave energy are emitted and subsequently reflected from the liquid level surface. Distance is calculated by the equation D = Transit time (round-trip)/2. Liquid level is then calculated by applying the user's Tank Height and Sensor Offset values.
