Figure 2-10. Top Mounting for Steam

Note
For wet steam, do not mount the flowmeter at the direct vertical position. Mounting at an angle
will avoid measurement inaccuracy due to water running along the bottom of the pipe.
2.5.7 Remote mounted transmitter
Instrument head connections differ between horizontal and vertical pipes. For horizontal lines,
the instrument connections are parallel to the pipe and for vertical lines, the instrument
connection are perpendicular.
Valves and fittings
Throughout the remote mounting process:
Use only valves, fittings, and pipe thread sealant compounds that are rated for the
service pipeline design pressure and temperature as specified in Appendix A:
Specifications and Reference Data.
Verify that all connections are tight and that all instrument valves are fully closed.
Verify that the Annubar sensor is properly oriented for the intended type of service:
liquid, gas, or steam (see “Flowmeter orientation” on page 14).
Impulse piping
Impulse piping connects a remote mounted transmitter to the Annubar sensor. Temperatures in
excess of 250 °F (121 °C) at the transmitter will damage electronic components; impulse piping
allows service flow temperatures to decrease to a point where the transmitter is no longer
vulnerable.
