Hello everyone, I am installing

Hello everyone,

I am installing a temporary Altitude valve to cut off flow to a reservoir once this reaches a water level.
My question is if the altitude valve is not at the same elevation as the sensing line, would there be any issue?
My sensing point is below the elevation of the altitude valve just as shown in the attachment

Thanks in advance

Issue no, design consideration yes

Altitude valves work on sensing pressure. You need to determine what the required sensing pressure is for the valve to shut off. The lower the valve is relative to the free surface of your water level, the greater the pressure setpoint for the cutoff. The Higher your valve is closer to the free surface of water level, the less your pressure setpoint for the cut off.

From OEM website

http://www.flomatic.com/valves/automatic-control-valves/altitude-control-valves/:

This type of Altitude Control Valve should be used when the supply pressure is appreciably higher (15 psi+) than the head developed by a full ground storage tank or reservoir.
