Safety Precautions and Instructions
MAG-UM-00158-EN-07Page 8 June 2018

SYSTEM DESCRIPTION
The Badger Meter M-Series® model M3000 electromagnetic flow meters are FM approved for Class I, Div 2 hazardous
locations. To achieve hazardous location ratings, electrodes in the flow tube are Intrinsically Safe, designed according to
Factory Mutual (FM) standards. Those standards limit the amount of energy that can be sent to electrodes to prevent a spark
from occurring.
Empty Pipe Detection
Badger Model M3000 meters are equipped with an Empty Pipe Detection feature. Empty Pipe Detection is accomplished by
positioning a third electrode close to the 12 o’clock position. Any time this electrode is not covered by fluid, for a minimum
of five seconds, the meter displays an Empty Pipe Detection condition, sends out an error message if desired, and stops
measuring to maintain accuracy. When the electrode is again covered with fluid, the error message disappears and the meter
continues measuring.
Amplier Mounting Conguration Options
Two amplifier-mounting configuration options are available to meet a variety of meter placement and
environmental conditions.
Meter Mount Configuration
The Meter Mount configuration has the amplifier mounted directly on the detector. This compact, self-contained
configuration minimizes installation wiring.
Figure 8: Meter mount
Remote Mount Configuration
• Remote Mount configuration places the amplifier and its functions at a location separate from the fluid flow and detector.
This configuration is necessary in situations where process fluid temperature or environment exceeds amplifier ratings. A
remote mounting bracket is supplied.
• The detector and amplifier are connected by wires, run through conduit, between junction boxes on the detector and
remote mounted amplifier. The distance between the detector junction box and amplifier junction box can be up to 100
feet (30 m).
• This configuration can also provide a more convenient amplifier programming and display placement for monitoring
meter readings.

System Description
MAG-UM-00158-EN-07 Page 9June 2018

METER/AMPLIFIER LOCATION, ORIENTATION AND APPLICATIONS
Remote Amplier 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…122° F (–20…50° C).
• If an indoor location is within 100 feet (30 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 display screen from
direct sunlight.
Temperatures
To prevent meter damage in any environment, minimum and maximum temperature ranges must be observed.
• The ambient temperature range surrounding the amplifier is – 4…122° F (–20…50° C).
• The ambient temperature range surrounding a remote junction box mounted to the detector is – 4…248° F
(–20…120° C).
Application Fluid Temperature Range Max. Ambient Temperature Liner Materials

Meter mounted amplifier 32…178° F (0…80° C) 122° F (50° C) Hard rubber
Pipelines and Fluid Flow Conditions
Pipeline and fluid flow conditions that should be avoided:
• Do not install the meter where extreme pipe vibrations exist. If vibrations are present, secure piping before and
after the meter with appropriate pipe supports. If vibrations cannot be restrained, consider mounting the amplifier
remotely.
• Avoid installing the detector close to pipeline valves, fittings or impediments that can cause flow disturbances.
• For detectors with PTFE liners, avoid installing the detector on suction sides of pumps.
• Avoid installing the detector on outlet sides of piston or diaphragm pumps. Pulsating flow can affect meter
performance.
• Avoid locations near equipment producing electrical interference such as electric motors, transformers, variable
frequency, and power cables.
• Verify both ends of the signal cables are securely fastened.
• Place power and signal cables in separate conduit.
• Place the meter where there is enough access for installation/maintenance purposes.
Meter/Amplier Location, Orientation and Applications
MAG-UM-00158-EN-07Page 10 June 2018

Meter Orientation
Mag meters can operate accurately in any pipeline orientation and can measure volumetric flow in forward and
reverse directions.
OTE:N A Forward Flow direction arrow is printed on the detector label.
Vertical Placement
Mag meters attain optimal performance when placed vertically, with liquid flowing upward and meter electrodes in a closed,
full pipe.
Figure 10: Vertical placement
Vertical placement allows the pipe to remain completely full, even in low flow, low pressure applications and it prevents any
solids build-up or sediment deposit or accumulation on the liner and/or electrodes.
OTE:N Carefully observe the “Forward Flow” label on the meter body and install the meter accordingly.
Horizontal Placement
In a horizontal piping orientation, mount the detector to piping with the flow measuring electrode axis in a horizontal plane
(3 and 9 o’clock).
This arrangement prevents solids build-up or sediment deposit or accumulation on the electrodes.

Straight Pipe Requirements
Sucient straight pipe runs are required at the detector inlet and outlet for optimum meter accuracy and performance. An equivalent of three

Pipe Reducer Requirements
With pipe reducers a smaller size 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 angle is not possible, install the custom pipe reducers as if they were fittings and install the
amount of straight pipe stated previously.
Figure 13: 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 14: Meter installed upstream of chemical injection point
If a meter must be installed downstream of a chemical injection connection, the recommended distance between the meter
and the injection point must be significant; 50…100 feet (15…30 meters). When the water/chemical solution reaches the
meter it must be a complete, homogeneous mixture. If the injection point is too close, the meter senses two (2) different
liquids (conductivity is different for each) and correct data output cannot be assured. The injection method: spaced bursts,
continuous stream of drips, a liquid or gas can also affect downstream readings by the meter.
Figure 15: Meter installed downstream of chemical injection point
Sometimes it’s difficult to specify the exact downstream placement distances because of the number of variables. Contact
Badger Meter Technical Support, 877-243-1010, to review your application if necessary.
Partially Filled Pipe Situations
In some locations, the process pipe may be momentarily only partially filled. Examples include: lack of backpressure,
insufficient line pressure and gravity flow applications.
To eliminate these situations, do not install the meter at the highest point of the pipeline.

Meter Gaskets and Grounding
Two other considerations to meter location, orientation and application are gasket and grounding requirements
and placement.
Two other considerations to meter location, orientation and application are gasket and grounding requirements
and placement.
Meter/Pipeline Connection Gaskets
Gaskets (not provided) must be installed between the detector isolating liner and the pipeline flange to ensure a proper and
secure hydraulic seal. Use gaskets compatible with the fluid flow. Center each gasket on the flange to avoid flow restrictions
or turbulence in the line.
Do not use graphite or any electrically conductive sealing compound to hold gaskets during installation. Measuring signal
accuracy could be affected.
If a grounding ring is used in the detector/pipeline connection, place the ring between two gaskets. (See
“Non-Conductive Pipe Grounding” on 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).
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 flange. Drill and tap the pipeline flanges 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 12 AWG size, between the grounding bolts on the
meter flanges and the bolts on the pipeline flanges. Do this on the inlet and outlet sides of the meter.
Figure 19: Conductive pipe grounding

MAG-UM-00158-EN-07 Page 13June 2018

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

Figure 20: Non-conductive pipe grounding
After the grounding rings, gaskets and meter are assembled to the pipeline, attach ground straps (provided) of copper wire, at
least 12 AWG size, to grounding bolts on meter flanges and to the grounding rings.
If your meter was ordered with an optional grounding electrode, the use of grounding rings is not necessary.

Output Wiring
The M-Series M3000 meter converts liquid flow into electrical signals. With proper output wiring and amplifier programming,
the signals are sent to, and used by, processing equipment used in operations or other procedures.
OTE:N Output wires and terminals are the same for meter mount or remote mount meters
Output wiring requires 18 to 22 AWG maximum, shielded wire (not supplied). Signal wire insulation temperature class should
exceed the maximum temperature where installed (typically, 185° F (85° C)).
Use conduit and conduit fittings (not supplied) rated for Class I, Div 2 hazardous locations.
NEMA 6P (IP67) Protection
THE FLOW METER WILL FULFILL ALL THE REQUIREMENTS REGARDING NEMA 6P IP67 PROTECTION IF THE
FOLLOWING POINTS ARE OBSERVED.
For applications with detector mounted amplifier (amplifier is located in submersed location):
• Both screw-on cover gaskets must be clean and undamaged prior to screwing the covers onto the amplifier housing.
• Both screw-on covers of the amplifier housing must be screwed on tightly (note: hand tightening is sufficient, over
tightening of the cover may result in damage to the covers or the housing.
• The four screws that attach the amplifier assembly to the detector neck must be firmly tightened.
• Cable glands that are screwed into the NPT connections located on the amplifier housing must be firmly tightened.
• Cable glands that are screwed into the NPT connections located on the amplifier housing must be approved for NEMA
6P (IP67) service. Additionally, the cable gland must be the correct size for the outside diameter of the cable being used.
NOTE: If the cable gland is not the correct size for the outside diameter of the cable, the gland will not properly seal
resulting in water infiltration.
• All cables must have a“drip loop”to prevent water from migrating down the cable into the cable gland.
