I am working on a project in which we require to fill a vessel with compressed air to a specified pressure and then test whether or not the vessel leaks.
To this point; I have developed the HMI and PLC code to basically open a fill valve, close the fill valve and then test the pressure after 1.5 seconds.
I am using Asco bubble tight valves, ML1100 w/1762-IF4 and 836E pressure transmitter from AB.
I can make the system work on small vessels but the stabilization of the air pressure is what is undermining the project.
Anyone have any thoughts on what I can do differently???
