Badger Meter M-Series M4000 - Manual (Page 9)

To ensure proper unit operation, the mag meter impact
ground (zero voltage reference) must be connected
to the liquid media and to a good, solid earth ground.
Perform grounding procedures after the meter is
connected to the pipeline.
Conductive Pipe Grounding
A grounding bolt is located on each mag meter fl ange. Drill
and tap the pipeline fl anges on each side of the meter and
install a grounding bolt to each.
To ground the unit, attach a ground strap (provided) of
copper wire, at least 12AWG size, between the grounding
bolts on the meter fl anges and the bolts on the pipeline
fl anges. Do this on the inlet and outlet sides of the meter.
Non-Conductive Pipe Grounding
If the process pipeline material is not electrically conductive
and your meter was not ordered with an optional grounding
electrode, place a grounding ring (available from Badger
Meter) between two gaskets on both ends of the meter.
SUPPLIED HARDWARE INCLUDES:
2 GROUNDING RINGS
4 BOLTS
4 LOCK WASHERS
2 NUTS
2 GROUND STRAPS
GASKETS RECOMMENDED
GROUNDING RING INSTALLATION KIT
After the grounding rings, gaskets and meter are assembled
to the pipeline, attach ground straps (provided) of copper
wire, at least 12AWG size, to grounding bolts on meter
fl anges and to the grounding rings.
If your meter was ordered with an optional grounding
electrode, the use of grounding rings is not necessary.
METER INSTALLATION PLANS and EXECUTION
Plan meter layout, location and installation. During
installation, remember these important points:
1. Heed all safety notifi cations.
2. Select a detector location with room for installation and
maintenance procedures.
3. Use proper lifting, rigging and moving procedures for
large units.
4. Consider the meter environment; particularly ambient and
process fl ow temperatures.
5. Consider the process pipeline (vibrations) and its fl ow
characteristics (valve and pump locations).
6. Meter orientation to the pipeline (vertical or horizontal).
7. Straight pipe requirements.
8. Pipe reducer requirements.
9. Special applications and/or situations.
For Remote Mount Units consider:
1. Amplifi
er location.
2. Remote amplifi er mounting bracket.
3. Proper conduit and conduit fi ttings.
4. Wiring and conduit locations.
REMOTE MOUNT AMPLIFIER
NOTE: Screws are supplied to attach the remote mount
bracket to the amplifi er. Screws are not supplied to attach
bracket at mounting location.
Remote Mount Amplifi er Location Requirements:
1. A sturdy and safe mounting surface capable of holding
the amplifi er weight (20 pounds, 9 Kg).
2. Within the allowable temperature range: -4°F to 122°F,
(-20°C to 50°C).
3. Access to amplifi er covers, ports, terminals, screen and
adjustments.
4. As close to the detector as possible.
5. Determine length and route of cable/conduit runs.
Mount Bracket to Amplifi er
1. Align bracket-mounting holes with amplifi er mounting
holes.
2. Attach bracket to amplifi er with supplied screws. Torque
screws to 80 in. lb.
