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.
