radar level gauge

It can be used, and there is no big problem. We used it on a vacuum crystallizer before, and the effect was not very good. I suggest you use a differential pressure type! Just pay attention to the selection

Radar level gauge can be used on vacuum tanks

There is no problem in using radar in vacuum tanks. The key depends on the material you use.

The measurement principle of radar level gauge is as follows: It can be learned from this that the radar level gauge that can be used on the vacuum tank adopts the working mode of transmitting-reflecting-receiving. The antenna of the radar level gauge emits electromagnetic waves. These waves are reflected by the surface of the measured object and then received by the antenna. The time from emission to reception of the electromagnetic wave is proportional to the distance to the liquid surface. The relationship is as follows: D=CT/2 where D - the distance from the radar level gauge to the liquid surface C - the speed of light T - the electromagnetic wave running time The radar level gauge records the time the pulse wave has experienced, and the transmission speed of the electromagnetic wave is constant, the distance from the liquid level to the radar antenna can be calculated, thereby knowing the liquid level of the liquid surface. In practical applications, there are two types of radar level gauges, namely frequency modulated continuous wave type and pulse wave type. The liquid level meter using frequency modulated continuous wave technology consumes a lot of power, must use a four-wire system, and has complex electronic circuits. The liquid level gauge using radar pulse wave technology has low power consumption and can be powered by two-wire 24V DC. It is easy to achieve intrinsic safety, has high accuracy and has a wider application range.

We wanted to switch to a radar level gauge because it was difficult to use a double-flange level gauge.

The vacuum version uses double flanges, which are defective. You can use radar, but there must be no interference with radar waves during extraction!

From the perspective of vacuum alone, radar level gauges can be used on vacuum tanks.

There is no problem with using a radar level gauge, just ensure the vacuum in the tank when installing.
