Measuring range
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 down the cable, which serves as
a conductor. When the signal reaches the material surface, it is
reflected back to the transmitter. The electronics then process
the signal and calculate the distance to the material
20 mA
surface based upon the time of flight. The
Emitted pulse
measurement data is converted to a 4-20
mA output with HART communication.

4 mA
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
(-30°C to 200°C).
