5.13.6 Pressure or absolute pressure measurement of a 
tank

  — Place the taps in the upper part of the tank.

  — Mount the transmitter above the elevation of the process    
    tap (both pressure and differential pressure transmitter can  
    be used).

 — 

Connect the transmitter to the tank.

5.13.7 Pressure or absolute pressure measurement of a 
liquid in a pipe

  — Place the tap at the side of the line.

  — Mount the transmitter (both pressure and differential  

 

    pressure transmitters) beside or below the tap for clean    
    fluids, above the tap for dirty fluids.

  — Connect the + (H) side of the transmitter to the pipe.
