We got a quote from a vendor of some chlorine equipment but it is pretty expensive. ($525) It appears to be a UE brand vacuum switch with an isolator diaphragm. They don't tell us exactly what materials they're suing for this assembly.
I just wanted to see what others have used or would recommend to monitor the presence of vacuum in the line that pulls chlorine gas through a flow regulator. The customer has had an issue in the past with the ejector pump failing to run or other issues that might cause a loss of vacuum and we would wire a contact from a vacuum switch to a PLC input to generate an alarm if it opens. It would be good to have an adjustable switch. I know from experience that chlorine and copper do not get along well, and the same appears to be true for stainless steel.
