Valcom GMG Guided Microwave Level Transmitter


The Valcom GMG Guide Wave Radar Level Transmitter is a 4-wire TDR-Sensor with single rod, wire rope or coaxial probe for continuous level measurement and point level detection in liquids and light solid, with analog and switching output.

The Valcom GMG uses TDR (Time Domain Reflectometry) technology, which means that low-energy, high-frequency electromagnetic impulses are propagated along the probe which is immersed in the liquid to be measured. When these impulses hit the surface of the liquid, part of the impulse energy is reflected back up the probe to the circuitry which then calculates the fluid level from the time difference between the impulses sent and the impulses reflected.
