The BinMaster GWR-1000 level sensor measures powders, bulk solids and liquids in vessels up to 78’ tall. It provides highly accurate, continuous level measurement utilizing time domain reflectometry (TDR) to measure the distance, level and volume of material contained in bins, tanks and silos. It performs reliably and is immune to dust, humidity, temperature, pressure and bulk density changes as well as noise that might be present when filling or emptying the vessel.
Using proven technology, the GWR-1000 features advanced two-wire TDR measurement technology with a low dead band (hysteresis) and accuracy of ± 0.2 inches (5 mm). The measurement data is converted to a 4-20 mA output with HART communication and can be viewed via a graphical display on the device or an optional local display using the SAP-300 plug-in display unit. BinMaster offers standard models for process temperatures from -22°F to 195°F (-30°C to 90°C) and high temperature models for temperature extremes from -22°F to 392°F (-30°C to 200°C). An 8 mm cable with a 1.5” NPT is offered for use in liquids and heavier bulk solid materials and a 4 mm cable with a 1” NPT can be used in lighter powders and bulk solids.
