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 ASME PCC-1 for proper bolt tightening. Make
sure the flowmeter is centered between flanges of the same nominal size as the flowmeter.
Insert integral temperature sensor (MTA option only)
The MTA option equips the vortex meter with a Type N Thermocouple. The transmitter uses
the process temperature measurement to compensate for changes in fluid density.
Saturated steam mass flow rate, liquid mass flow, and corrected volumetric flow can all take
advantage of the dynamic density corrections for increased accuracy.
The temperature sensor is coiled and attached to the electronics bracket. Remove the
styrofoam around sensor and insert temperature sensor into the hole at the bottom of the
meter body. There is no need to remove the opposite end from the electronics. Tighten
