Mounting A P Style Pressure Transmitter - ABB 266 HART Series Operating Instruction

5.6 Mounting a P style pressure transmitter

(266Gxx, 266Axx, 266Hxx, 266Nxx)
The pressure transmitter can be mounted directly on the
manifold.
A mounting bracket for wall or pipe mounting (2" pipe) is also
available as an accessory.
Ideally, the pressure transmitter should be mounted in a
vertical position to prevent subsequent zero shifts.

vertical, the filling liquid exerts hydrostatic pressure on the
measuring diaphragm, resulting in a zero shift. In such an event, the
zero point can be corrected via the zero push-button or via the "set
PV to zero" command. Please refer to the [configuration section] for
further details. For transmitters without diaphragm seals the Vent /
Drain considerations below should be taken into consideration.
