Guided Wave Radar Level Gauge
HART Field Device
The AH-GWR series is a simple bracket-mounting four-wire loop-powered Guided wave radar level gauge, with a 4-to-20mA output. The guided wave radar level gauge uses an antenna as the sensor and samples and analyzes the signal through the time-domain reflection principle. When the instrument is working, when the electromagnetic wave encounters a change in the dielectric constant, it will be reflected, and the antenna will receive the reflected signal and calculate the time interval between the transmission and reflection.
The AH-GWR series replaces the earlier models AH-G and AH-N, providing improved accuracy while maintaining 100% compatibility.
The output signal of the AH-GWR series guided wave radar level gauge supports 4-20 mA current signal and HART communication protocol.
FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
