Product Overview

GML801-B radar level gauge series sensor is a 26GHz high-frequency radar-type level measuring instrument with a maximum measurement distance of 80 meters. the antenna is further optimized and processed, and a new type of fast microprocessor can perform higher-speed signal analysis and processing, so that the instrument can be used for some complex measurement conditions such as reactors and solid silos.

 

Working Principle

Radar level antennas emit narrower microwave pulses that are transmitted downward through the antenna. after the microwave contacts the surface of the measured medium, it is reflected back and received again by the antenna system. the signal is transmitted to the electronic circuit and automatically converted to the level signal. the time taken is almost instantaneous.

Product Features 

1.the antenna size is small for easy installation; non-contact radar, no wear and no pollution.
2.Hardly affected by corrosion and foam; hardly affected by atmospheric water vapor, temperature and pressure changes.
3.the severe dust environment has little effect on the operation of the high-frequency level gauge.
4.Shorter wavelengths give better reflection on inclined solid surfaces.
5.the beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.
6.the measurement blind area is smaller, and it can also achieve good results for small tank measurement.
7.High signal-to-noise ratio for better performance even in fluctuations.
8.High frequency is the best choice for measuring solid and low dielectric constant media.
