Mounting a P style pressure transmitter

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.
IMPORTANT
If the transmitter is installed inclined with respect to the 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 paragraph 5.5for further details. For transmitters without diaphragm seals the Vent / Drain
considerations below should be taken into account.
