2.3.4 Basic Mounting Procedure, Standard Coupling

Select the procedure, below, applicable for the size meter supplied.

2.3.4.1 25 - 40 mm (1 - 1-1/2 inch) Meter Sizes

Refer to Figures 2-1 and 2-7 to supplement the following procedure.
1. Install flange adapter on meter as shown in Figure 2-7. Align the flange adapter device (supplied
with meter) so that the mounting stud clearance holes in the meter body are not obstructed.
2. Place one of the gaskets inside the housing end ring next to the inlet end of the ceramic spool; so
that the gasket will be between the pipe flange and the meter body.
3. Insert meter in pipeline in accordance with the flow direction arrow. Next while supporting the
meter, insert one, or more, of the mounting studs through the clearance holes in the upstream pipe
flange, so that these studs enter the holes in the meter body. This will help support the meter.
4. Insert the other (downstream) gasket between the meter outlet and the downstream pipe flange,
with the gasket inside the meter's downstream end ring. The mounting studs can then be guided
through the clearance holes in the downstream pipe flange. Similarly, insert the remaining mounting
studs through the clearance holes provided.
5. Thread nuts on both ends of the four mounting studs, finger-tight.
6. To center the magnetic flowmeter with the longitudinal axis of the pipeline, press down firmly on
the centering device. This will force-spread the mounting studs, thereby centering the meter body.
Maintain pressure on centering device and tighten nuts of the mounting studs until nuts are suffi-
ciently tight to prevent movement of meter relative to the flanges.
7. Tighten the stud nuts in even increments to prescribed torque as shown in Figure 2-6,using
prescribed tightening sequence to maintain even pressure distribution around the respective flanges.
Bolt torque should be limited to that which is sufficient to produce a positive seal for the application
as given in Table 2-1.

2.3.4.2 50 - 100 mm (2 - 4 inch) Meter Sizes

Refer to Figures 2-2 and 2-7 to supplement the following procedure.
1. Insert both of the two lower mounting studs (see Figure 2-7, Detail "I" 4-Bolt Flange, or Detail "II"
8-Bolt Flange, as applicable) through the clearance holes in the pipe flange, so that approximately
half the stud length extends past the flange face. (Start with either the upstream or downstream
flange, as convenient.)
2. Slip an adapter sleeve* on both of the mounting studs. The two mounting studs can now be guided
through the clearance holes in the downstream (typical) flange.
3. Place a gasket inside the meter end ring at both the inlet and outlet ends of the meter, so that the
gasket will be between the ceramic spool and the adjacent pipe flange.
4. Place the CK-MAG magnetic flowmeter between the two pipe flanges, with the meter body foot
piece (opposite the neck) being seated between the two adapter sleeves. The meter must be oriented
in accordance with the flow direction arrow.
