P&ID Selecting between two pumps
P&ID Selecting between two pumps
(OP)
I have an application where I have to holding tanks with LOW and HIGH level float switches in each tank. The outlets of each tank tie together and are the suction to a duplex pump skid. I want to know what the proper symbols are to show on the P&ID that either set of float switches can turn the pumps on or off. For lack of something better, I was planning to show it like the sketch I attached.
