Guided Wave Radar Continuous Level Sensor

Sept. 11, 2012

BinMaster Level Controls  announces the introduction of the BinMaster Guided Wave Radar (GWR-100) level sensor for measuring powders, bulk solids and liquids in vessels up to 78’ tall. The GWR-100 provides highly accurate level measurement utilizing time domain reflectometry (TDR) to continuously 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. 

The BinMaster 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. “Guided Wave Radar is a natural addition to the wide variety of level measurement technologies offered in the BinMaster product line,” stated Todd Peterson, vice president of sales for BinMaster. “The GWR-1000 is suitable for all types of powders, granules, solids and liquids and can be used in vessels of most any shape or diameter, including narrow tanks in a variety of industries including food, grain, seed, feed, cement, asphalt, minerals, quarries, steel, chemicals, and power generation.”
