METER GASKETS AND GROUNDING

Gasket and grounding requirements must be considered when determining the meter location, orientation and application

Meter/Pipeline Connection Gaskets

You must install gaskets (not provided) between the detector's isolating liner and the pipeline flange to ensure a proper and

secure hydraulic seal Use gaskets that are compatible with the fluid Center each gasket on the flange to avoid flow

restrictions or turbulence in the line

GASKETS RECOMMENDED

Figure 15: Meter/Pipeline Connection Gaskets

During installation, do not use graphite or any electrically conductive sealing compound to hold the gaskets This could

compromise the accuracy of the measuring signal
If you are using a grounding ring in the detector/pipeline connection, place the ring between two gaskets (See

Non-Conductive Pipe Grounding section, page 14 )

Meter Grounding

Process pipeline material can be either electrically conductive (metal) or not electrically conductive (made of or lined with

PVC, fiberglass or concrete)

IMPORTANT

It is essential that the mag meter amplifier’s input ground (zero voltage reference)

be electrically connected to the liquid media and to a good, solid earth ground reference

Conductive Pipe Grounding

To achieve an adequate ground, the meter body MUST be electrically connected to the liquid media The mag meter flanges

are provided with grounding bolts for this purpose
If the pipe material is electrically conductive, simply install grounding straps between these grounding bolts and the mating

flanges
To ensure a good electrical connection at the mating flanges, we recommend that you drill and tap the flanges and install a

grounding screw (not provided)
These grounding straps must be copper wire, at least 12 AWG size They must be connected on both sides (inlet and outlet) of

the detector and to a local, earth ground
