BinMaster’s MultiBob level sensor system is an inventory management system that provides an average bin level from measurements taken by two, and up to 32, SmartBob2 or SmartBob TS-1 sensors installed on the top of a single bin, tank, silo or flat storage warehouse containing powders, granulars or bulk solid materials. The SmartBob sensors are strategically located in the vessel to monitor critical measuring points and using eBob software, are programmed to measure materials at scheduled time intervals or on demand. The advanced eBob software compiles the measurement data to calculate an average level or headroom and estimated percentage full.
