Hi,
there is a vortex flowmeter. There are two valves at the front and behind side of these flowmeters. Flowmeter is mounted vertical and flow direction is from down to up. When the valves are closed, some fluid stays in it. But no flow occurs when the valves are close. But not everytime, sometimes flowmeter give full output (20 ma). How can I solve this problem?
