2.2.2 Installing Wafer-Style Flowmeters (cont.)
To install the meter, complete the following steps:
1. Turn off the flow of process gas, liquid or steam. Verify that the line is not pressurized. Confirm that the
installation site meets the required minimum upstream and downstream pipe diameters.
2. Insert the studs for the bottom side of the meter body between the pipe flanges. Place the wafer-style meter
body between the flanges with the end stamped with a flow arrow on the upstream side, with the arrow head
pointing in the direction of flow. Center the meter body inside the diameter with respect to the inside diameter
of the adjoining piping.
3. Position the gasket material between the mating surfaces. Make sure both gaskets are smooth and even with no
gasket material extending into the flow profile. Obstructions in the pipeline will disturb the flow and cause
inaccurate measurements.
4. Place the remaining studs between the pipe flanges. Tighten the nuts in the sequence shown in Figure 5 on
page 11. Check for leaks after tightening the flange bolts.
