SYSTEM DESCRIPTION
The BadgerMeter model M2000 electromagnetic flow meter is intended for fluid metering in most industries including water,
wastewater, food and beverage, pharmaceutical and chemical. The meter is intended for the metering of all fluids with electric
conductivity of at least 5 µS/cm (20 µS/cm for demineralized water). The meter has a high degree of accuracy, and measuring
results are independent of density, temperature and pressure.
The basic components of an electromagnetic flow meter are:
• The sensor, which includes the flow tube, isolating liner and measuring electrodes.
• The transmitter, which is the electronic device responsible for the signal processing, flow calculation, display and
outputsignals.

Figure 1: Transmitter and sensor
The construction materials of the wetted parts (liner and electrodes) should be appropriate for the intended type of service.
Review all the compatibilities consistent with the specifications.
Each meter is factory tested and calibrated. A calibration certificate is included with each meter.
Measuring Principle
In accordance with Faraday’s induction principle, electric voltage is induced in a conductor moving through a magnetic
field. In the case of electromagnetic flow measurement, the moving conductor is the flowing fluid. Two opposite measuring
electrodes conduct the induced voltage, which is proportional to flow velocity, to the transmitter. Flow volume is calculated
based on pipe diameter.

UNPACKING AND INSPECTION
Follow these guidelines when unpacking the 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 if 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 sensors 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.
• Do not remove the liner protectors until you are ready to install.
OTE:N 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…71° 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 transmitter, junction box, sensor neck or cables.
• Use a crane rigged with soft straps to lift and move meters with flow tubes that are 2…8 inches (50…200 mm). Place the
straps around the sensor body, between the flanges, on each side of the sensor.
• 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
Page 7March 2022 MAG-UM-01272-EN-21

• Use the sling-rigged method to lift large sensors into a vertical position while they are still crated. Use this method to
position large sensors vertically into pipelines.
Figure 3: Sling-Rigged lifting methods
• Do not lift a sensor with a forklift by positioning the sensor 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 sensor's flow
tube to hoist the unit. This could damage the isolating liner.
Do not lift sensor with forklift Do not lift or rig lifting devices through sensor

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 15. There are two transmitter mounting options: a meter mount option and a
remote mount option.
Meter mount Remote mount
Figure 5: Transmitter mounting options
Transmitter Mounting Conguration Options
There are two configuration options for mounting the transmitter and many options to accommodate a variety of
meter-placement and environmental conditions.
Meter Mount Configuration
The meter mount configuration has the transmitter mounted directly on the sensor. This compact, self-contained
configuration minimizes installation wiring.
Remote Mount Configuration
The remote mount configuration places the transmitter at a location away from the fluid flow and sensor. This is necessary in
situations where process fluid temperature or the environment exceeds transmitter ratings.
The sensor and transmitter are connected by wires, run through conduit, between junction boxes on the sensor and the
transmitter. The distance between the sensor junction box and transmitter junction box can be up to 500 feet (150 meters). A
remote mounting bracket is supplied.
Use the remote version in the following cases:
• Sensor protection class IP 68
• Fluid temperature > 212° F (100° C)
• Strong vibrations
Remote Transmitter Outdoor Location
The transmitter 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 (150 meters) of the sensor, consider increasing the cable length and mounting the
transmitter indoors.
• At minimum, fabricate a roof or shield over and/or around the transmitter to protect the LCD screen from direct sunlight.
• Do not install the signal cable close to power cables, electric machines or similar.
• Fasten signal cables. Due to capacity changes, cable movements may result in incorrect measurements.
Submersible Option
If you are installing the meter in a vault, order the remote transmitter option. Do not install the transmitter inside a vault.
We also recommend ordering the remote meter package with the submersible option (NEMA 6P / IP68). This eliminates any
potential problems resulting from humidity or temporary flooding in the vault.
Meter Location, Orientation and Applications
Page 9March 2022 MAG-UM-01272-EN-21

The National Electronics Manufacturer's Association (NEMA) 6P enclosures are constructed for indoor or outdoor use. The 6P
enclosures provide protection against access to hazardous parts. They also 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)
which provide an additional level of protection against corrosion and that are not damaged by the external formation of ice
on the enclosure.
Temperature Ranges
TO PREVENT DAMAGE TO THE METER, STRICTLY OBSERVE THE TRANSMITTER’S AND SENSOR’S MAXIMUM
TEMPERATURE RANGES.
• To prevent damage to the meter, strictly observe the transmitter and sensor temperature ranges.
• In regions with extremely high ambient temperatures, protect the sensor from extreme temperatures.
• In cases where fluid temperature exceeds 212° F (100° C), use the remote mount version.
Transmitter Ambient temperature –4…140° F (–20…60° C)
Sensor Fluid temperature
PTFE/PFA –40…302° F (–40…150° C)
Hard rubber 32…176° F (0…80° C)
Soft rubber 32…176° F (0…80° C)
Protection Class
To fulfill requirements of the protection class, follow these guidelines:
• Make sure body seals are undamaged and in proper condition.
• Firmly screw in all the body screws.
• Outer diameters of the wiring cables must correspond to cable inlets (for M20 Ø 5....10 mm). In cases where cable inlet is
not used, put in a dummy plug.
• Tighten cable inlets.
• If possible, lead cable away downwards to prevent humidity from entering cable inlet.
The standard option is protection class IP 67. If you require a higher protection class, use the remote mount version. NEMA
6P/IP 68 is an option for the sensor with the remote mount version.
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, use the remote mount option.
• Do not install the sensor close to pipeline valves, fittings or impediments that can cause flow disturbances.
• For sensors with PTFE liners, do not install the sensor on suction sides of pumps.
• Do not install the sensor on outlet sides of piston or diaphragm pumps. Pulsating flow can affect meter performance.
• Avoid installing the sensor near equipment that produces electrical interference such as electric motors, transformers,
variable frequency or power cables.
• Make sure 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.
• Install the meter with the forward flow label on the meter body matching the pipeline flow.
Meter Location, Orientation and Applications
Page 10 March 2022MAG-UM-01272-EN-21

• For sensors with PTFE liner, only remove the protective cap on the flange or on the threaded pipes of milk pipe screws per
DIN 11851 shortly before installation.
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 sensor 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 transmitter so that the cable glands are facing down.
Horizontal Placement
When installing the meter on a horizontal pipe, mount the sensor 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.

Empty Pipe Detection
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 displays an empty pipe detection condition. The meter sends out an error message
and stops measuring flow. When the electrode is again covered with fluid, the error message disappears and the meter
resumes measuring.
Straight Pipe Requirements
Run sufficient straight-pipe at the sensor 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 (2) diameters are
required on the outlet (downstream) side.
In applications with limited space, the M2000 can be installed with zero straight pipe requirements and fulfils the accuracy
according OIML R49 and MID Annex MI-001.

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 a maximum slope angle of 8 degrees on each side 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.

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 50…100 feet (15…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 likely results in inaccurate measurements. The injection method—spaced bursts,
continuous stream of drips or liquid or gas—can also affect downstream readings by the meter.

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 allows the sensor to remain full of liquid at all times.

METER GASKETS AND GROUNDING
Gaskets and grounding are required for proper meter installation.
IMPORTANT
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
IMPORTANT
It is essential that the transmitter’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 sensor'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.
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 sensor/pipeline connection,
place the ring between two gaskets. See “Recommended Installation
with Grounding Rings” on page 16 for more instructions.
GASKETS RECOMMENDED
GROUNDING RING

Figure 15: Meter/pipeline connection gaskets and grounding rings
Meter Grounding and Potential Equalization
In order to obtain an accurate measurement, sensor and fluid need to be on the same electric potential.
Process pipeline material can be either electrically conductive (metal) or not electrically conductive (made of or lined with
PVC, fiberglass or concrete).
If flange or intermediate flange versions with additional grounding electrode are used, grounding is provided by the
connected pipeline.
IN CASE OF A TYPE WITH FLANGE, USE A CONNECTION CABLE (MINIMUM 4 MM²) BETWEEN GROUNDING SCREW
ON THE METER FLANGE TO THE COUNTERFLANGE IN ADDITION TO THE FIXING SCREWS. VERIFY THAT A PERFECT
ELECTRIC CONNECTION IS PROVIDED.
COLOR OR CORROSION ON THE COUNTERFLANGE MAY HAVE A NEGATIVE EFFECT ON THE ELECTRIC CONNECTION.
IN CASE OF TYPES WITH INTERMEDIATE FLANGES, THE ELECTRIC CONNECTION TO THE SENSOR IS DONE VIA TWO 1/4
AMP PLUGS INSTALLED ON SENSOR’S NECK.

Recommended Installation with Grounding Rings
IMPORTANT
BadgerMeter recommends the installation of a pair of grounding rings between the mating flanges at both ends of the meter. See
Figure 15 on page 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.
Meter Gaskets and Grounding
Page 16 March 2022MAG-UM-01272-EN-21

Plastic or Lined Pipelines
If non-conductive pipelines or pipelines lined with non-conductive material are used, install an additional grounding
electrode or grounding rings between the flanges. Grounding rings are installed like gaskets between the flanges and are
connected with a grounding cable to the meter (See Figure 15 on page 15).
WHEN GROUNDING RINGS ARE USED, MAKE SURE THE MATERIAL IS RESISTANT TO CORROSION. IF AGGRESSIVE FLUIDS
ARE MEASURED, USE GROUNDING ELECTRODES.
Pipelines with Cathodic Protection
For pipelines with cathodic protection, install the meter potential-free. No electric connection from the meter to the pipeline
system may exist and power supply is to be provided via isolating transformer.
USE GROUNDING ELECTRODES (GROUNDING RINGS ALSO NEED TO BE INSTALLED ISOLATED FROM THE
PIPELINESYSTEM).
Observe national rules regarding potential-free installation

Electrically Disturbed Environment
If the pipe material is in an electrically disturbed environment or if metallic pipelines that are not grounded are used, ground
the meter as shown in Figure 18 to make sure that measurement is not influenced.

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.
• Use only the type of power source suitable for electronic equipment. If in doubt, contact your distributor. Make sure
that any power cables are of a sufficiently high current rating.
• All units must be grounded to eliminate risk of electric shock.
• Failure to properly ground a unit may cause damage to that unit or data stored within it.
Opening the M2000 Meter Cover
The M2000 transmitter's design lets you open the cover without completely removing it.
COVER IS ATTACHED WITH DISPLAY RIBBON CABLE.
TO OPEN THE COVER YOU 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 transmitter.
3. Loosen each of the remaining screws so that the round head of the screw clears the top edge of the cover.
4. Lift and pivot the cover into the open position.
Figure 19: Open cover
Power Connections
• For the 3 × M20 cable inlets only use flexible electric cables.
• Use separate cable inlets for auxiliary power, signal and input/output cables.
Wiring
Page 18 March 2022MAG-UM-01272-EN-21

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 a three-wire sheathed connection cable suitable for the rating of this device. For signal
output use 18…22 gauge (0.25…0.75 mm2) shielded wire. Overall cable diameter between 0.20…0.39inch(5…10mm).
TO PREVENT ACCIDENTS, CONNECT MAIN POWER ONLY AFTER ALL OTHER WIRING HAS BEEN COMPLETED.
The transmitter 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 transmitters.
Auxiliary Power
DO NOT CONNECT METER UNDER IMPRESSED MAINS VOLTAGE.
TAKE NATIONAL APPLICABLE RULES INTO ACCOUNT.
OBSERVE TYPE PLATE (MAINS VOLTAGE AND FREQUENCY).
1. Slightly loosen both of the left cover screws and loosen the two right cover screws completely. Open cover to the left side.
2. Push auxiliary power cable through the upper cable inlet.
