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.
