wet differential pressure switch
If you were installing one of these on a horizontal pipe, would you :
A) tap off the side or bottom of the pipe
B) tap off the top of the pipe
C) not worry about it
reason being to avoid air from getting into the switch. Would this affect the operation of the switch??
obviously air compresses and water doesn't but the veris has a slow response option that should negate any "bounce" in pressure.
I've always wondered about this but I've never seen anything in the installation instruction about it.
