output signals.
Amplier
®
Figure 1: Amplifier and detector
The construction materials of the wetted parts (liner and electrodes) should be appropriate for the specifications on the
intended type of service. We recommend that you review all of the compatibilities consistent with the specifications.
Each meter is factory tested and calibrated. A calibration certificate is included with each meter.
Page 5 February 2019 MAG-UM-01272-EN-09
Unpacking and Inspection
UNPACKING AND INSPECTION
Follow these guidelines when unpacking the M-Series equipment.
• If a shipping container shows any sign of damage, have the shipper present when you unpack the meter.
• Follow all unpacking, lifting and moving instructions associated with the shipping container.
• Open the container and remove all packing materials. Store the shipping container and packing
materials in the event the unit needs to be shipped for service.
• Verify that the shipment matches the packing list and your order form.
• Inspect the meter for any signs of shipping damage, scratches, or loose or broken parts.
OTE:N If the unit was damaged in transit, it is your responsibility to request an inspection report from the carrier within
48 hours. You must then file a claim with the carrier and contact Badger Meter for appropriate repairs or replacement.
• All detectors with polytetrafluoroethylene (PTFE) liners are shipped with a liner protector on each end to maintain proper
form of the PTFE material during shipping and storage.
OTE:N Do not remove the liner protectors until you are ready to install.
• Storage: If the meter is to be stored, place it in its original container in a dry, sheltered location. Storage temperature ranges
are: –40…160° F (–40…70° C).
Rigging, Lifting and Moving Large Units
WHEN RIGGING, LIFTING OR MOVING LARGE UNITS, FOLLOW THESE GUIDELINES:
• DO NOT lift or move a meter by its amplifier, junction box or cables.
• Use a crane rigged with soft straps to lift and move meters with flow tubes that are between two inches and eight inches
(50 mm and 200 mm). Place the straps around the detector body, between the flanges, on each side of the detector.
• Use the lifting lugs when lifting meter flow tubes that are 10 inches (250 mm) in diameter or larger.
®
®
Place straps between flanges. Use lifting lugs with 10-inch or larger meters.

Unpacking and Inspection
• Use the sling-rigged method to lift large detectors into a vertical position while they are still crated. Use this method to
position while they are still crated. Use this method to position large detectors vertically into pipelines.
Figure 3: Sling-Rigged lifting methods
• Do not lift a detector with a forklift by positioning the detector body on the forks, with the flanges extending beyond the
lift. This could dent the housing or damage the internal coil assemblies.
• Never place forklift forks, rigging chains, straps, slings, hooks or other lifting devices inside or through the detector's flow
tube to hoist the unit. This could damage the isolating liner.
Do not lift detector with forklift. Do not lift or rig lifting devices through detector.

Meter Location, Orientation and Applications
METER LOCATION, ORIENTATION AND APPLICATIONS
Gasket and grounding requirements must be considered when determining the meter location, orientation and application.
See "Meter Gaskets and Grounding" on page 12. The M2000 meter provides two amplifier mounting options: a meter mount
option and a remote mount option.
Meter mount Remote mount
Figure 5: Amplifier mounting options
Temperature Ranges
TO PREVENT DAMAGE TO THE METER, STRICTLY OBSERVE THE AMPLIFIER’S AND DETECTOR’S MAXIMUM
TEMPERATURE RANGES.
• In regions with extremely high ambient temperatures, protect the detector.
• In cases where fluid temperature exceeds 212° F (100° C), use the remote version.
Amplifier Ambient temperature – 4…140° F (–20…60° C)
Detector Fluid temperature
PTFE / PFA – 40…302° F (– 40…150° C)
Hard rubber 32…176° F (0…80° C)
Remote Amplier Outdoor Location
The amplifier can be installed and operated outdoors. However, it must be protected from the elements, as follows:
• The ambient environment/temperature rating for the unit is –4…140° F (–20…60° C).
• If an indoor location is within 500 feet (152 meters) of the detector, consider increasing the cable length and mounting the
amplifier indoors.
• At minimum, fabricate a roof or shield over and/or around the amplifier to protect the LCD screen from direct sunlight.
Pipelines and Fluid Flow
Take the following precautions during installation:
• Do not install the meter on pipes with extreme vibrations. If pipes are vibrating, secure the piping with appropriate pipe
supports in front of and behind the meter. If vibrations cannot be restrained, mount the amplifier in a remote location.
• Do not install the detector close to pipeline valves, fittings or impediments that can cause flow disturbances.
• For detectors with PTFE liners, do not install the detector on suction sides of pumps.
• Do not install the detector on outlet sides of piston or diaphragm pumps. Pulsating flow can affect meter performance.
• Avoid installing the detector near equipment that produces electrical interference such as electric motors, transformers,
variable frequency, and power cables.
• Verify that both ends of the signal cables are securely fastened.
• Place power cables and signal cables in separate conduits.
• Place the meter where there is enough access for installation and maintenance tasks.

Flow Meter
Meter Location, Orientation and Applications
Meter Orientation
Mag meters can operate accurately in any pipeline orientation and can measure volumetric flow in forward and
reverse directions as long as the pipe is completely full.
OTE:N A "Forward Flow" direction arrow is printed on the detector label.
Vertical Placement
Mag meters perform best when placed vertically, with liquid flowing upward and meter electrodes in a closed, full pipe.
Figure 6: Vertical placement
Vertical placement allows the pipe to remain completely full, even in low flow, low pressure applications, and it prevents
solids build-up, sediment deposit and accumulation on the liner and electrodes.
OTE:N Carefully observe the “Forward Flow” label on the meter body and install the meter accordingly. When
installed vertically, rotate amplifier so that cable glands are facing down.
Horizontal Placement
M2000 meters are equipped with an Empty Pipe Detection feature. If an electrode mounted in the pipe is not covered by fluid
for five seconds, the meter will display an Empty Pipe Detection condition. The meter will send out an error message and
stop measuring flow. When the electrode is again covered with fluid, the error message disappears and the meter will begin
measuring.
When installing the meter on a horizontal pipe, mount the detector to the pipe with the flow-measuring electrode axis in a
horizontal plane (three and nine o’clock). This placement helps prevent solids build-up, sediment deposit and accumulation
on the electrodes.

Straight Pipe Requirements
Sufficient straight-pipe runs are required at the detector inlet and outlet for optimum meter accuracy and performance. An
equivalent of 3…7 diameters of straight pipe is required on the inlet (upstream) side to provide a stable flow profile. Two
diameters are required on the outlet (downstream) side.

Meter Location, Orientation and Applications
Pipe Reducer Requirements
With pipe reducers, a smaller meter can be mounted in larger pipelines. This arrangement may increase low-flow accuracy.
There are no special requirements for standard, concentric, pipe reducers.
Custom fabricated pipe reducers must have an approximate slope angle of 15 degrees to minimize flow disturbances and
excessive loss of head. If this is not possible, install the custom pipe reducers as if they were fittings and install the required
amount of straight pipe.
Figure 9: Pipe reducer requirements
Chemical Injection Applications
For water line applications with a chemical injection point, install the meter upstream of the injection point. This eliminates
any meter performance issues.
Figure 10: Chemical injection point downstream of meter
If a meter must be installed downstream of a chemical injection connection, the distance between the flange and the
injection point should be between 50 and 100 feet (15 and 30 meters). The distance must be long enough to allow the
water/chemical solution to reach the meter in a complete, homogeneous mixture. If the injection point is too close, the meter
senses the two conductivities for each liquid. This will likely result in inaccurate measurements. The injection method—
spaced bursts, continuous stream of drips or liquid or gas—can also affect downstream readings by the meter.
Figure 11: Chemical injection point upstream of meter
Sometimes, due to circumstances, it is difficult to specify the exact downstream placement distances. Contact Badger Meter
Technical Support to review your application if necessary.

Meter Location, Orientation and Applications
Partially-Filled Pipe Situations
In some locations, the process pipe may be momentarily only partially filled. Examples include: lack of back pressure,
insufficient line pressure and gravity flow applications.
To eliminate these situations:
• Do not install the meter at the highest point of the pipeline.
• Do not install the meter in a vertical, downward flow section of pipe.
• Always position the ON/OFF valves on the downstream side of the meter.

To minimize the possibility of partially-full pipe flows in horizontal, gravity or low pressure applications, create a pipe
arrangement that ensures the detector remains full of liquid at all times.

Grounding Ring
Gaskets Recommended
Meter Gaskets and Grounding
METER GASKETS AND GROUNDING
Gaskets and grounding are required for proper mag meter installation.
MPORTANTI
If you received grounding rings with your meter, install them. Electromagnetic meters require a good ground for proper operation.
Grounding rings also help protect the edge of the liner from debris that may flow from the pipe.
Meter/Pipeline Connection Gaskets
MPORTANTI
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.
You must install gaskets (not provided) between the detector's isolating liner, grounding rings and the pipeline flange to
provide 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.
Grounding Ring
Figure 15: Meter/pipeline connection gaskets and grounding rings
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
"Recommended Installation with Grounding Rings".)
Meter Grounding
Process pipeline material can be either electrically conductive (metal) or not electrically conductive (made of or lined with
PVC, fiberglass or concrete).
Recommended Installation with Grounding Rings
MPORTANTI
Badger Meter recommends the installation of a pair of grounding rings between the mating flanges at both ends of the meter. See
Figure 15.
Connect the grounding straps to both of the grounding rings and to a good, solid earth ground. Grounding rings are available
in stainless steel. If your fluid is too aggressive for stainless steel, order a meter with the optional grounding electrode in a
material compatible with the fluid.

Amplier Mounting Conguration Options
AMPLIFIER MOUNTING CONFIGURATION OPTIONS
There are two configuration options for mounting the amplifier. There are many options to accommodate a variety of
meter-placement and environmental conditions.
Meter Mount Conguration
The meter mount configuration has the amplifier mounted directly on the detector. This compact, self-contained
configuration minimizes installation wiring.
Remote Mount Conguration
The remote mount configuration places the amplifier at a location away from the fluid flow and detector. This is necessary in
situations where process fluid temperature or the environment exceeds amplifier ratings.
The detector and amplifier are connected by wires, run through conduit, between junction boxes on the detector and the
amplifier. The distance between the detector junction box and amplifier junction box can be up to 500 feet (152 meters). A
remote mounting bracket is supplied.
Submersible Option
If you are installing the meter in a vault, you should order the remote amplifier option. You must not install the amplifier inside
a vault. We also recommend ordering the remote meter package with the submersible option (NEMA 6P). This will eliminate
any potential problems resulting from humidity or temporary flooding in the vault.
OTE:N The National Electronics Manufacturer's Association (NEMA) 6P enclosures are constructed for indoor or outdoor use
to provide protection against access to hazardous parts; to provide a degree of protection against ingress of solid
foreign objects and water (hose directed water and the entry of water during prolonged submersion at a limited
depth); that provide an additional level of protection against corrosion and that will be undamaged by the external
formation of ice on the enclosure.
WIRING
Wiring Safety
AT INSTALLATION, BE SURE TO COMPLY WITH THE FOLLOWING REQUIREMENTS:
• Disconnect power to the unit before attempting any connection or service to the unit.
• Do not bundle or route signal lines with power lines.
• Keep all lines as short as possible.
• Use twisted pair shielded wire for all output wiring.
• Observe all applicable, local electrical codes.
Opening the M2000 Meter Cover
The M2000 amplifier's design lets you open the cover without completely removing it.
COVER IS ATTACHED WITH DISPLAY RIBBON CABLE.
To open the cover you will need a blade screwdriver.
Follow these steps:
1. Disconnect power to the unit.
2. Completely remove the two screws from either the left or the right side of the amplier.

Power Connections
External Disconnect
• Install an external disconnect switch or circuit breaker that meets local standards.
• Position the M2000 meter in an accessible location.
• Position and identify the disconnect device so as to provide safe and easy operation.
• Label the disconnect device as being for the mag meter.
AC Power Wiring
For the AC power connections, use three wire-sheathed cable with an overall cable diameter of 0.2…0.45 inch (5…12 mm).
For signal output, use 18…22 gauge (0.25…0.75 mm2) shielded wire. Overall cable diameter between 0.12…0.35 inch
(3…9 mm).
TO PREVENT ACCIDENTS, CONNECT MAIN POWER ONLY AFTER ALL OTHER WIRING HAS BEEN COMPLETED.
The amplifier is a microprocessor device. It is important that the power supply be as “clean” as possible. Avoid using power
lines that feed heavy loads: pumps, motors, etc. If dedicated lines are not available, a filtering or isolation system may
be required.
Power wiring is the same for meter mount and remote mount amplifiers.
Remote Mount Installation
If you are installing the M2000 amplifier in a remote location, review the procedures in this section.
Mount Bracket to Amplifier
1. Align bracket-mounting holes with amplier mounting holes.
2. Attach bracket to amplier with supplied screws. Torque screws to 80 inch pounds.
Wiring Configuration
Wiring between the detector and the M2000 amplifier comes complete from the factory. If your installation requires the use
of conduit, we recommend that you follow these steps when wiring the detector to the amplifier.
1. Remove the junction box lid. Carefully remove the wires connected to the terminal blocks that run to the M2000 amplier.
See the chart below for a reference of wire color to terminal connection.
2. Run cable through the conduit from the amplier location while retaining the wiring of the cable to the amplier,
as supplied.
Page 14 February 2019MAG-UM-01272-EN-09
3. Complete conduit assembly on both ends and rewire the cable into the junction box as it was previously wired.

Conguring Input/Output (I/O)
CONFIGURING INPUT/OUTPUT I/O
This section describes wiring the following M2000 meter inputs/outputs:
• Analog output
• Digital input
• Digital outputs
• Communication
Once the sensor and the amplifier have been wired, wire any inputs and outputs to the M2000 amplifier.
Do not connect the main power connection until you have made all other wiring connections. Follow all of the safety
precautions and local code to prevent electrical shock and damage to the electronic components.
