Swing Check Position?
Swing Check Position?
(OP)
I have a 1500# steam swing check valve with no external indication of the open or close position of the check. Does anybody know if there is an external/clamp on device that can determine the position of the check without modifying the valve (ASME Boiler valve)?

I'd expect a small signal, and you'll probably need to also measure the temperature so you can compensate the LOHED.
