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 ASME PCC-1 for proper bolt tightening. Make
sure the flowmeter is centered between flanges of the same nominal size as the flowmeter.
Spacers
Spacers are available with the flowmeter to maintain the Rosemount 8800A flowmeter
dimensions. If a spacer is used, it should be downstream of the meter body. The spacer kit
comes with an alignment ring for ease of installation. Gaskets should be placed on each side
of the spacer.
