In closed systems, the transmitter location is
restricted by the maximum allowable distance
above the lower tap. In pressurized systems, this is
the same as the 1 atmosphere equivalent seen
previously. In sub-atmospheric systems (vacuum
systems), the transmitter should be mounted at or
below the lower tap. This ensures the transmitter
always sees a positive pressure on both the
measurement and the reference sides.
In two seal systems, the distance between the taps
becomes the reference offset from zero. The
calculations are the same regardless of where the
transmitter is mounted.

Answer / raja

differential pressure transmitter can be used to measure the tank level. High pressure tubing to be taken from the bottom of the tank and low pressure tubing to be taken from the top of the tank. This differential pressure is directily proportional to the tank level.
