Which kind of on-site liquid level gauge is best for ammonia cooler?
Thread Content
Our on-site liquid level gauges for ammonia coolers are all glass liquid level gauges. It is difficult to confirm the liquid level on site. What kind of liquid level gauge do you use?
We also use a glass plate liquid level meter, and the remote transmitter is a float level transmitter. The use of both instruments is not ideal.
It should be possible to use a stainless steel magnetic flap remote transmission liquid level gauge. :handshake
Either one should be fine, but it is recommended that the glass level gauge be frost-proof. That's it.
There is oil deposit in the lower part of the ammonia cooler, which blocks the root of the liquid level gauge. Do you have any good methods to deal with it?
Use a diaphragm differential pressure transmitter to solve the problem
There are liquefied gas type magnetic flap level gauges that can also be used in liquid ammonia situations.
We use a capacitive liquid level gauge, which feels relatively stable and easy to debug. There are no problems such as pressure pipe blockage. If the poster is interested, I will send the model number tomorrow.
We use a flip-plate level gauge. With remote transmission. The effect is passable.
It is also good to use a float level gauge, which is very convenient for maintenance and debugging.
