Dwyer Series GWL guided wave radar transmitter for liquids

Click2Contact

The Series GWL guided wave radar transmitter for liquids is a level transmitter providing an analog and switching output (4-20 mA as well as a NC SPST switch output) to provide continuous level indication of liquids.

The sensor can output level indication as a continuous measurement reading through its analog output or it can alter that information into freely adjustable switching output signals. Time domain reflectometry technology provides accuracy, stability and the suppression of disturbance signals, allowing the GWL to measure precisely even when operating close to interfering structures.

The transmitter is available with either a rigid or flexible probe depending on the application installation required as well as the custom probe length. One of the GWL characteristics is virtually no installation restrictions making it suitable for small tanks, tall and narrow nozzles, and various other types of processing and storage applications. The guided wave radar transmitter for liquids also features factory setting configuration via the HART communication protocol.
