Having a problem with inlet pressure/septa purge not holding pressure or stabilizing flow.
I have a split inlet, 2:1, pressure set at 92, typically holds at 47. But total flow jumps around and never stabilizes.
Leak check Service: Total flow continually wildly fluctuates (200-350) and will not stabilize, column indicates stable flow of 7.6
Diagnostic: Pressure stays at 47, test pressure is 10, Inlet, Septa Purge, and Columns flows all stable, but Total fluctuates constantly fluctuates. Inlet Flow Sensor has alot of noise from 200-500 constantly. Back inlet flow control set at 73, Fluctuates 200-400.
I have replaced and cleaned out Everything in maintenance, septa, split liner, even changed column, purge trap. I even cleaned out the septa purge line from inlet to sensor and outlet, that line is open.
