Flanged-style flowmeter mounting

Physical mounting of a flanged-style flowmeter is similar to installing a typical section of
pipe. Conventional tools, equipment, and accessories (such as bolts and gaskets) are
required. Tighten the nuts following the sequence shown in
Note
The required bolt load for sealing the gasket joint is affected by several factors, including
operating pressure and gasket material, width, and condition. A number of factors also affect
the actual bolt load resulting from a measured torque, including condition of bolt threads,
friction between the nut head and the flange, and parallelism of the flanges. Due to these
application-dependent factors, the required torque for each application may be different.
Follow the guidelines outlined in the ASME Pressure Vessel Code (Section VIII, Division 2) for
proper bolt tightening. Make sure the flowmeter is centered between flanges of the same
nominal size as the flowmeter.
