Installing the Transmitter

2.4.1Integral installations

If you chose an integral installation (see Figure 2-1), there are no special mounting instructions for the transmitter.

You can rotate an integrally mounted transmitter up to 360° in 90° increments, to one of four possible positions on the core processor base. See Figure 2-2.

CAUTION

Damaging the wires that connect the transmitter to the core processor can cause measurement error or flowmeter failure.

To reduce the risk of damaging the wires, do not move the transmitter more than a few inches from the core processor. When reassembling the flowmeter, ensure that the wires will not be bent or pinched in the housing.

To rotate the transmitter on the core processor:

1.Loosen each of the four cap screws (4 mm) that fasten the transmitter to the base.

2.Rotate the transmitter counter-clockwise so that the cap screws are in the unlocked position.

3.Gently lift the transmitter straight up, disengaging it from the cap screws. Do not disconnect or damage the wires that connect the transmitter to the core processor.

4.Rotate the transmitter to the desired orientation, and align the slots with the cap screws. Do not pinch or stress the wires.

5.Gently lower the transmitter onto the base, inserting the cap screws into the slots.

6.Rotate the transmitter clockwise so that the cap screws are in the locked position.

7.Tighten the cap screws, torquing to 20 to 30 in-lbs (2,3 to 3,4 N-m).
