Selection of level gauges with particulate matter handling capability
Thread Content
There is a tank with stirring and micro-pressure that requires level measurement; the medium is a mixture of metal powder and water. I would like to ask the experts: what other types of level gauges are good alternatives to differential pressure level gauges? Thank you :hug:
Are there any requirements regarding the opening position? A differential pressure type is relatively ideal. Since it is a mixture, top-mounted instruments such as magnetostrictive or radio frequency admittance types can be considered.
The top-mounted type can be used to avoid the feed inlet
1. The selection of the filling material for differential pressure transmitters is quite critical; it’s not suitable to use differential pressure measurement methods for such media. 2. For ferromagnetic media, magnetic-based technologies or similar measurement methods are not appropriate. 3. If the level of mixing is low, radio frequency admittance or weight-based methods can be used; for purposes of preventing overflow or generating output alarms as switches, similar switch types will suffice.
Anything with magnetism won’t work; I think radar and ultrasound methods also won’t suffice. The mixing requirement at the site is at least 60 revolutions per minute. The liquid surface has significant fluctuations
The switch has been installed... The owner mainly wants to monitor the liquid level. The stirring speed should be no less than 60 revolutions per minute. So I spent a long time thinking but couldn’t figure out what to use. The differential pressure is merely passable. :sleepy:

A zero-leakage gas collection and pressure sensing sensor with a diaphragm that does not come into contact with liquid – a level gauge of our company, Shuaike, which is the first of its kind in the world. With 20 years of operational experience, it is used for measuring substances such as desulfurization lime slurry, drilling fracturing slurries, concrete cement mortar, tunnel backfill mortar, and electroplating wastewater that is severely scaled.

It was possible to do so for many years back, right? What’s going on? !
An ultrasonic level gauge could be considered.
I’m going to turn on the computer and try again.
Wow,,, the computer supports GIF images. . . If it works with a computer motherboard, then why doesn’t it work with a mobile phone one?
