Can a float level switch be used in a vacuum environment?

2009-08-04View Original

Thread Content

In a vacuum environment, the float level switch does not respond to rising liquid levels. As a result, overflow due to high liquid levels often occurs. Could experts help analyze the reasons for this?

Due to the inappropriate selection, it is recommended to replace the measuring instrument with a radar or ultrasonic level gauge. Reason: In a vacuum environment, the floating ball gets flattened (that is, the sphere deforms), which leads to inaccurate level measurement as you mentioned. The indication is usually on the low side, resulting in material overflow.

I’m telling you clearly, it’s not possible. What medium are you testing? Let’s talk and help you choose another watch.

Ultrasonic waves cannot be used in a vacuum either (sound waves cannot travel there, and temperature has a significant impact). To make use of the existing installation location, a tuning fork vibration-based switch can be used, or guided wave radar can be considered for measuring continuous values, as neither is affected by pressure.

Thank you all for your comments. I understand. It seems that the only option is to make a change.:victory:

The level switch can be used in a vacuum. Unless the float you purchase is of poor quality.

It works in vacuum conditions, offers stable and reliable performance, allows for adjustment of upper and lower limits, is very easy to install, and is not expensive. Please refer to the animations on the website of water level controllers: www.shuiweikaiguan.com

The float level switch operates on a mechanical principle and is not affected by vacuum; in your case, it might be due to a mechanical failure – perhaps the moving parts are stuck~~~~
