Wafer-Style Flowmeter
Alignment and Mounting
Center the wafer-style meter body inside diameter with respect to the inside
diameter of the adjoining upstream and downstream piping. This will ensure
that the flowmeter achieves its specified accuracy.
Alignment rings are provided with each wafer-style meter body for centering
purposes. Follow these steps to align the meter body for installation. Refer to
Figure 2-7 on page 2-11.
