Transmitter Orientation and Power Supply

2.1Overview

This chapter describes:

•Rotating the transmitter on the sensor (optional)

•Rotating the user interface module on the transmitter (optional)

•Power supply requirements and wiring

2.2Moisture 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.

CAUTION

Condensation or excessive moisture entering the transmitter could damage the transmitter and result in measurement error or flowmeter failure.

To reduce the risk of measurement error or flowmeter failure:

•Do not mount the sensor so that the conduit openings on the transmitter point upward.

•Ensure the integrity of gaskets and O-rings.

•Grease the O-rings every time the transmitter housing is opened and closed.

•Install drip legs on conduit or cable.

•Seal the conduit openings.

•Fully tighten all covers.

2.3Rotating 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.
