Level-detection system is immune to steam and buildup
BinMaster
The GWR-2000 guided microwave level transmitter (photo; p. 33) is used for inventory management and level detection in silos and provides continuous level measurement in vessels up to 100 ft tall with accuracies of±0.08 in. (2 mm). It uses time-domain reflectometry (TDR) to continuously measure the distance, level and volume of powders or solids in bins, tanks and silos. This sensor features hazardous location approvals, a very small upper dead zone, and assures highly accurate level measurement in low-dielectric materials down to 1.3. It has 4–20-mA and Modbus RTU communication options, making it compatible with a human-machine interface or programmable logic controller, as well as the company’s eBob LAN-based software program or BinView cloud-based monitoring. It excels in challenging conditions such as vessels with high dust and air movement or excessive noise, says the company. — BinMaster, Lincoln, Neb.
