3.5.6 Flowmeter grounding
Grounding is not required in typical vortex applications; however, a proper ground will
eliminate possible noise pickup by the electronics. Grounding straps may be used to ensure
that the meter is grounded to the process piping. If you are using the transient protection
option (T1), grounding straps are required to provide a proper low impedance ground.
Note
Properly ground flow meter body and transmitter per the local code.
To use grounding straps, secure one end of the grounding strap to the bolt extending from
the side of the meter body and attach the other end of each grounding strap to a suitable
ground.
3.6 Electronics considerations
Both integral and remote mounted electronics require input power at the electronics. For
remote mount installations, mount the electronics
against a flat surface or on a pipe that is up to two inches (50 mm) in diameter.
Remote mounting hardware includes an L bracket that is stainless steel and one stainless
steel u-bolt. See Appendix A: Specifications and Reference Data, “Dimensional drawings”
on page 97 for dimensional information.
3.6.1 High-Temperature installations
Install the meter body so the electronics are positioned to the side of or below the pipe as
shown in Figure 3-2 on page 24. Insulation may be required around the pipe to maintain an
ambient transmitter temperature below 185 °F (85 °C) or the more restrictive temperature
ratings marked on hazardous locations tags.
