Guided Wave Radar Reliable, Accurate, Continuous Level Measurement BinMaster’s GWR-1000 guided microwave level transmitter utilizes time domain reflectometry (TDR) to continuously measure the distance, level and volume of powders, granules and solids in bins, tanks and silos. It is also suitable for use in a variety of liquids. The transmitter is mounted on the top of the vessel in an unobstructed area through a 1” or 1-1/2” NPT opening. A single, flexible stainless steel cable with a counter weight – custom made to the height of the vessel – is suspended from the transmitter to the bottom of the vessel. The transmitter emits a low power microwave signal guided along the cable. When the pulse reaches the surface of the medium being measured, the pulse energy is reflected up the probe to circuitry that then calculates the level based on the time difference between the pulse being sent and the reflected pulse received. The sensor can output the analyzed level as a continuous measurement reading via an analog output. 2-wire TDR technology 4-20 mA with HART communication Accuracy of ± 0.2 inches (5 mm) Temperature range of -22°F to 195°F HT model maximum temperature 392°F Local graphical display optional Upper Dead Zone 20 mA Measuring range The GWR radar signal has a large detection area – 360° and extending out around the probe. When the electromagnetic pulse comes in to contact with product on the probe, the signal is returned and analyzed Emitted pulse to see whether it reflects the true level. Because the true level always has a larger return signal than the return signal generated from the smaller mass sticking to the probe, the sensor can easily Detection area identify the true surface of the material. around probe Reflected pulse 4 mA Lower Dead Zone Measures Powders, Bulk Solids & Liquids in Vessels up to 78’ The GWR-1000 is suitable for 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. It measures reliably and accurately and is immune to dust, humidity, temperature, pressure and bulk density changes as well as noise that might be present during filling or emptying, even in chunky materials like rock or stone. BinMaster offers standard GWR models for process temperatures from -22°F to 195°F (-30°C to 90°C) and the high temperature GWR-HT models for temperature extremes from -22°F to 392°F (-

BinMaster’s GWR-1000 comes from our factory calibrated, configured, and ready to use. Installation is quick, simple and by plant personnel, which helps minimize costs. The cable comes custom-made to the length needed for the vessel. It installs easily through an existing or new 1 or 1-1/2” NPT opening. BinMaster offers both powder coated carbon steel and stainless steel mounting plates should one be needed. The GWR-1000 can be retrofit in existing vessels or installed in new vessels and does not require special configuration to compensate for structural or environmental conditions that might...
