Yes we can measure pressure with the help of Differential pressure transmitter,we have to connect the HP side of the transmitter to the process line where we are going to measure the pressure,But only thing is we can measure only up to the range of minimum since Differential pressure transmitter will be in range om mmwc.

Answer / manishahir

we measure pressure using differential pressure transmitter by connect the HP side of the transmitter to the process line and LP side of transmitter should be open in atmospheric.

Answer / dhiru patel

Yes,we can use DP tx for pressure measurement for vacuume pressure(absolute PT) and low gauge pressure measurement.It depends on service,pressure range and diaphragm material.

Answer / ayaz

we know that dp transmitter working principle on pressure difference and in dp type transmitter two ranges URV and LRV
1 LRV is low side value and 2 URV is high side value 
SO only reed high side pressure this is vessel pressure
or connect the hart comminucator and then display the vessel pressure 

Answer / johnan

actually we can use the differential pressure transmitter to measure the flow and level, not the pressure, how, if level, it calculate the difference of high side and low side of the transmitter, then it convert to the level using formula,it is a very long explanation,this is only a laymans term...
