Product Description
High Temperature Solid And Liquid 80ghz Radar Level Transmitters FMW21 RS485 Modbus 150m
The general principle of the FM continuous wave radar level gauge is that the radar emits electromagneticwaves on the top of the tank, and the electromagnetic waves are received by the radar after being reflectedby the medium. The frequency difference δf between the received signal and the transmitted signal isproportional to the distance R from the surface of the medium: R=C (speed)*δf (frequency difference)/2/K(frequency modulation slope). Because the speed of light C and the frequency modulation slope K areknown, the frequency difference δf can be estimated to obtain the distance R from the radar installationposition to the material surface, and then through the known total height of the tank, subtract the spatialdistance from the radar to the material surface (referred to as Empty height) to get the height of the materiallevel.
Application
Liquid:Crude oil, light oil, natural gas, methanol, ethanol, ammonia water, benzene, polystyrene, esters, watervapor, liquid carbon dioxide, paint, turpentine, chemical water, oil level measurement in oil depots,chemical liquid storage tanks in chemical plantsSolidSlurry, raw coal bunker, pulverized coal silo, fly ash silo, limestone, coking pulverized coal, cold return ore,raw material silo, powder silo, coal ash silo, stone silo, raw meal silo, cement silo, slag storage siloCharacteristic1.
