BinMaster’s GWR-1000 guided microwave level transmitter utilizes time domain reflectometry (TDR) to continuously measure the distance, level and volume of powders, granules and solids in bins, tanks and silos. It is also suitable for use in a variety of liquids. The transmitter is mounted on the top of the vessel in an unobstructed area through a 1” or 1-1/2” NPT opening. A single, flexible stainless steel cable with a counter weight – custom made to the height of the vessel – is suspended from the transmitter to the bottom of the vessel. The transmitter emits a low power microwave signal guided along the cable. When the pulse reaches the surface of the medium being measured, the pulse energy is reflected up the probe to circuitry that then calculates the level based on the time difference between the pulse being sent and the reflected pulse received. The sensor can output the analyzed level as a continuous measurement reading via an analog output.
