When the primary flow element (orifice plate, venturi,
averaging pitot tube) is sized to design conditions, the
result is a DP value corresponding to 100% flow rate. That
value is used to configure the DP transmitter.

For level, measurements are made from the transmitter datum
or installed position to the maximum level, with
compensation for the medium's specific gravity. When remote
seals are used, the specific gravity of the fill fluid is
accounted for in a compensating calculation.

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
