Description of Digital microwave radar level meter low price guided wave radar level transmitter
The wave radar level gauge can emit high-frequency microwaves and propagate along the probe rod. When encountering the measured medium, the dielectric constant changes abruptly, causing reflections. The time interval between the transmitted pulse and the reflected pulse of the guided wave radar level gauge is proportional to the distance of the measured medium. At the same time, the guided wave radar level gauge can also measure the interface of two different media, making full use of the difference in the dielectric constant of the media. However, the measurement condition is that the upper layer medium is non-conductive, or its dielectric constant is more than 10 times smaller than that of the lower layer medium. The working mode of pulse can measure medium with small dielectric constant, and it is safe for use in various metal and non-metal containers, without harm to human body and environment. Can measure solid material level, liquid level, liquid interface
