METER DESCRIPTION

Badger

Model M-3000 electromagnetic meters are FM approved for Class I, Div 2 hazardous locations. To achieve hazardous location ratings electrodes in the ﬂ ow 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 M-3000 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 ﬂ uid, for a minimum of ﬁ ve 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 ﬂ uid, the error message disappears and the meter continues measuring.

Meter Mount

Remote Mount Conﬁ guration Remote Mount conﬁ guration places the ampliﬁ er and its

functions at a location separate from the ﬂ uid ﬂ ow and detector. This conﬁ guration is necessary in situations where process ﬂ uid temperature or environment exceeds ampliﬁ er ratings. A remote mounting bracket is supplied.

Detector and ampliﬁ er are connected by wires, run through conduit, between junction boxes on the detector and remote mounted ampliﬁ er. The distance between the detector junction box and ampliﬁ er junction box can be up to 100 feet (30m).

This conﬁ guration can also provide a more convenient ampliﬁ er programming and display placement for monitoring meter readings.

Ampliﬁ er Mounting Conﬁ guration Options

Two ampliﬁ er-mounting conﬁ guration options are available to meet a variety of meter placement and environmental conditions.

APPLICATIONS Remote Ampliﬁ er Outdoor Location

The ampliﬁ er can be installed and operated outdoors. However, protection from the elements must be considered:

6. Verify both ends of the signal cables are securely fastened.

7. Place power and signal cables in separate conduit.

8. Place the meter where there is enough access for installation/maintenance purposes.

1. Be aware of the ambient environment and temperature ratings for the unit -4°F to 122°F (-20°C to 50°C).

2. If an indoor location is within 100 feet (30m) of the detector installation, consider increasing the cable length and mounting the ampliﬁ er indoors.

3. At a minimum, fabricate a roof or shield over and/or around the ampliﬁ er to protect the LCD display screen from sunlight.

Temperature

To prevent meter damage in any environment, minimum and maximum temperature ranges must be observed.

1. For remote ampliﬁ er applications, the ﬂ uid temperature range is -4°F to 248°F (-20°C to 120°C) at a maximum ambient temperature of 122°F (50°C) for the following liner materials: PFA, PTFE and Halar

2. For remote ampliﬁ er applications, the ﬂ uid temperature range is 32°F to 178°F (0°C to 80°C) at a maximum ambient temperature of 122°F (50°C) for the following liner materials: Hard rubber and soft rubber.

3. For meter mounted ampliﬁ er applications, the ﬂ uid temperature range is -4°F to 212° (-20°C to 100°C) at a maximum ambient temperature of 122°F (50°C) for the following liner materials: PFA, PTFE and Halar.

4. For meter mounted ampliﬁ er applications, the ﬂ uid temperature range is 32°F to 178°F (0°C to 80°C) at a maximum ambient temperature of 122°F (50°C) for the following liner materials: Hard rubber and soft rubber.

Meter Orientation

Mag meters can operate accurately in any pipeline orientation and can measure volumetric ﬂ ow in forward and reverse directions.

NOTE: A Forward Flow direction arrow is printed on the detector label.

Vertical Placement

Mag meters attain optimal performance when placed vertically, with liquid ﬂ owing upward and meter electrodes in a closed, full pipe.

Vertical placement allows the pipe to remain completely full, even in low ﬂ ow, low pressure applications and it prevents any solids build-up or sediment deposit or accumulation on the liner and/or electrodes.

NOTE: Carefully observe the “Forward Flow” label on the meter body and install the meter accordingly.

5. The ambient temperature range surrounding the ampliﬁ er is -4°F to 122°F (-20°C to 50°C.)

6. The ambient temperature range surrounding a remote junction box mounted to the detector is -4°F to 248°F (-20°C to 120°C.)

Pipelines and Fluid Flow

Pipeline and ﬂ uid ﬂ ow conditions that should be avoided:

1. 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 can’t be restrained, consider mounting the ampliﬁ er remotely.

2. Avoid installing the detector close to pipeline valves, ﬁ ttings or impediments that can cause ﬂ ow disturbances.

3. For detectors with PTFE liners, avoid installing the detector on suction sides of pumps.

4. Avoid installing the detector on outlet sides of piston or diaphragm pumps. Pulsating ﬂ ow can affect meter performance.

5. Avoid locations near equipment producing electrical interference such as electric motors, transformers, variable frequency, power cables, etc.

Horizontal Placement

In a horizontal piping orientation, mount the detector to piping with the ﬂ ow 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

Pipe Reducer Requirements

With pipe reducers a smaller size meter can be mounted in larger pipelines. This arrangement may increase low ﬂ ow 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 ﬂ ow disturbances and excessive loss of head. If this is not possible, install the custom pipe reducers as if they were ﬁ ttings and install the amount of straight pipe stated previously.

spaced bursts, continuous stream of drips, a liquid or gas can also affect downstream readings by the meter.

Sometimes it’s difﬁ cult 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

It is possible to encounter situations where the process pipe is momentarily only partially ﬁ lled. Examples include; lack of backpressure, insufﬁ cient line pressure, gravity ﬂ ow applications, etc.

To eliminate these situations:

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.

If a meter must be installed downstream of a chemical injection connection, the recommended distance between the meter and the injection point must be signiﬁ cant; 50 to 100 feet (15 to 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:

Do not install the meter in

the highest point of the pipeline

Do not install the meter in a vertical,

downward ﬂ ow section of pipe.

FLOW

FLOWFLOW

RIGHT

ALWAYS locate ON/OFF valves on the

downstream side of the meter

To minimize the possibility of partially full pipe ﬂ ows in horizontal, gravity or low pressure applications, create a pipe arrangement that insures the detector remains full of liquid at all times

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.

GROUNDING RING INSTALLATION KIT

SUPPLIED HARDWARE INCLUDES: 2 GROUNDING RINGS 4 BOLTS 4 LOCK WASHERS 2 NUTS 2 GROUND STRAPS

Meter Gaskets and Grounding

Two other considerations to meter location, orientation and application are gasket and grounding requirements and placement.

Meter/Pipeline Connection Gaskets

GASKETS RECOMMENDED

Gasket(s) (not provided) must be installed between the detector isolating liner and the pipeline ﬂ ange to ensure a proper and secure hydraulic seal. Use gaskets compatible with the ﬂ uid ﬂ ow. Center each gasket on the ﬂ ange to avoid ﬂ ow 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 section.)

After the grounding rings, gaskets and meter are assembled to the pipeline, attach ground straps (provided) of copper

Meter Grounding

Process pipeline material can be either electrically

wire, at least 12AWG size, to grounding bolts on meter ﬂ anges and to the grounding rings.

conductive (metal) or not electrically conductive (made of or lined with PVC, ﬁ berglass or concrete).

If your meter was ordered with an optional grounding electrode, the use of grounding rings is not necessary.
