Transmitter Orientation and Power Supply
2.1 Overview
This chapter describes:
• Rotating the transmitter on the sensor (optional)
• Rotating the user interface module on the transmitter (optional)
• Power supply requirements and wiring
2.2 Moisture protection
When rotating or wiring the transmitter, guard against condensation or excessive moisture inside the
transmitter housing. Be sure that the conduit openings are completely sealed after all installation and
wiring procedures have been performed.
Improperly sealed housings can expose electronics to moisture, which can cause measurement error
or flowmeter failure. Install the meter so that the conduit openings do not point upward, and install drip
legs in conduit or cable. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing
covers and conduit openings.
2.3 Rotating the transmitter on the sensor (optional)
For easier access to the user interface or the wiring terminals, the transmitter can be rotated on the
sensor in 45° increments, for eight different orientations.
To rotate the transmitter on the sensor:
1. Referring to Figure 2-1, unscrew the clamp that holds the transmitter to the feedthrough.
2. Gently lift the transmitter on the feedthrough until it disengages from the notches on the
feedthrough. You will not be able to remove the transmitter completely.
3. Rotate the transmitter to the desired position.
4. Lower the transmitter, sliding it onto the notches on the feedthrough.
5. Replace the clamp and tighten the screw.
