The GWR-1000 model is a Bin Master which has a high-quality level sensors which measures the powders, bulk solids and liquids in container up to 78 tall. This device supports a highly-accurate, continuous level measurement which applies time domain reflectometry (TDR),which is used to calculate the distance, level and volume of material which consists of bins,tanks and silos.It performs efficiency and resistant to dust humidity, temperature, pressure and bulk quantity.
