QM-FMR-120 purge-and-clean Radar Material Level Gauge

Details

I.  Introduction

Developed on FMCW radar technology, the QM-FMR-120 purge-and-clean radar material level gauge is mainly used for measuring the level of silo, displaying status and uploading data.

The radar level gauge has very good adaptability and anti-interference ability especially for high dust and high water vapor environment. The level gauge uses an aluminum alloy casing, with a novel design and light equipment. It has a purge function and an automatic purge-and-clean control function: you can set the temperature over-limit purge to reduce the temperature, and you can set the timer and quantitative purge control to remove the antenna dust, and can start and stop the purge remotely and wirelessly.

With abundant interfaces, the gauge is equipped with 4 ~ 20mA current output, RS485 digital interface, purge-and-clean control and switching value. Integrated GPRS wireless transmission module can realize wireless transmission and multi-terminal data viewing.
