2.3.5 Basic Mounting Procedure

Refer to Figure 2-6 to supplement the following procedure.
1. Insert both of the two lower mounting studs 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.)
3. Install a gasket next to the flange face.
4. Slip an adaptor sleeve* on both of the mounting studs, and then install the other gasket
required. The two mounting studs can now be guided through the clearance holes in the
downstream (typical) gasket and its associated flange.
*Exception: Adaptor sleeves are not required for size 1/10 to 1-1/2 in. meters placed
between ANSI Class 150 pipeline flanges.
5. Place the MINI-MAG Magnetic Flowmeter between the two flange gaskets, with the meter
resting on the two adaptor sleeves. The meter must be oriented in accordance with the
flow direction arrow.
6. Install the two upper mounting studs and adaptor sleeves as shown in Figure 2-6. Note
that when the sleeves are properly located, only four adaptor sleeves are needed for
positioning the meter. In systems with an 8-bolt flange pattern, insert the four remaining
mounting studs through the clearance holes in the upstream and downstream flanges.
7. Thread nuts on both ends of the 4 (or 8) mounting studs, finger-tight.
8. As the meter body is positioned properly by the adaptor sleeves, it is only necessary to
tighten the stud nuts to complete the mounting procedure. Tighten the nuts in a "star" pattern
as shown in Figure 2-5 and in even increments; to produce an even pressure distribution
around the flange faces. Bolt torque should be limited to that sufficient to produce a positive
seal for the application.
