A pressurized tank contains a líquid, SG = 1.0, and the level measuring pressure taps are 100 inches apart. A pneumatic differential pressure transmitter is used to measure level. The leg that connects the top of the tank to the transmitter is filled with tank líquid. The top tap should be connected to:
A. The low-pressure tap on the transmitter.
B. The high-pressure tap on the transmitter.
C. Either the high- or the low-pressure tap.
D. The high-pressure tap but through a seal chamber
