Endpoint Installation Guidelines
ORI-UM-00025-EN-09
In-line Connectors
An in-line connector is an optional feature that allows connectivity to AMR/AMI devices without the need for a field splice kit.
When the endpoint and encoder have connectors, join the connector ends as shown in Figure 2. With the proper orientation,
the connector ends go together easily.
• With 308 in-line connectors, align the notch on one connector (endpoint side) with the corresponding projection on
the other (encoder side) and push the ends together for the correct fit. See 308 In-line connector, Figure 2.
• With Nicor in-line connectors, hold the connector ends with the arrow side up, point the arrows toward each other
and push the ends together for the correct fit. See Nicor In-line connector, Figure 2.
You will hear a“click“ when the ends are firmly seated and the connection is secure.

SCOPE OF THIS MANUAL
This manual contains installation, operation and maintenance procedures for the BadgerMeter® Recordall® Compound Series
meters with magnetic drives. To ensure efficient operation of the meters, read, understand and follow the instructions in this
manual. Retain the manual in a location where it is readily available.
PRODUCT INFORMATION
Product Description
The Compound Series meters combine two metering technologies in one innovative package. A positive displacement
chamber measures low flow, while a turbine chamber records high flow. The compound meters are available in 2", 3", 4" and
6" sizes.
A spring-loaded valve assembly controls the flow through each of the two measuring elements to provide maximum accuracy
and performance.
The basic components of the compound meter are a housing, Turbo Series head assembly and cover assembly with disc
chamber assembly. The Turbo head assembly includes a Recordall register or encoder for high flow totalization and complete
turbo head components (cage and rotor). The cover assembly includes a Recordall register or encoder for low flow totalization
and a complete chamber assembly.
The output of both measuring elements, the disc and turbo, is transmitted to each Recordall register or encoder by means
of ceramic magnets. The register or encoder is permanently sealed in a controlled environment relative to humidity and
cleanliness, thus assuring longevity of performance.

Preinstallation Considerations
Before proceeding any further with the installation, rst read the instructions in the paragraphs immediately following to
become familiar with the requirements and procedures involved.
OTE:N The Recordall Compound Series meters are designed for operation in HORIZONTAL piping arrangements.
• Be sure that the meter flow range and size of the meter coincide with the intended service and demand for water.
THE LIFE OF THE COMPOUND METER WILL BE CURTAILED IF OPERATED AT FLOW RATES HIGHER THAN SPECIFIED.
• The meters are designed for use in cold water service (up to 120° F or 27° C) within the applicable flow requirements
for compound meters. For use with water at higher temperatures, consult your Badger Meter representative or nearest
Badger Meter regional sales office.
• If solid material is present in the water to be metered, a strainer must be installed in the service piping upstream of the
meter. The strainer, in addition to protecting the meter from debris in the line, minimizes the effect of velocity profile
distortions or turbulence caused by changes in pipe direction or valving resulting in more accurate registration. Contact
your Badger Meter representative for information on Recordall Plate Strainers.
• Avoid locating the meter in close quarters. Allow sufficient space to permit access for meter reading, testing,
and maintenance.
• Because of the need to test large meters periodically to verify their performance, it is recommended that a bypass system
be incorporated into the piping arrangement. This will also provide a means of performing periodic cleanout and routine
maintenance without interrupting service to the customer. A test port is incorporated in the meter housing and can be
used for field accuracy testing.
• The Recordall Compound Series meter is accuracy and pressure tested prior to shipment, therefore no field adjustments
are required. As turbine performance is directly related to the flow conditions of the water stream entering the meter,
upstream fittings and piping changes can adversely affect flow registration. For valid registration and proper performance,
consider the following installation considerations:
◊ When installing the meter with a Badger Meter Plate Strainer, a minimum of 5 pipe diameters of straight, unobstructed
pipe is required upstream of the meter. (A minimum of 10 pipe diameters of straight unobstructed pipe is required
upstream of a meter installed without a plate strainer. The deletion of a strainer, however, is not recommended.) This
allows for dampening of velocity profile distortions caused by items such as elbows, pumps and dirt traps upstream
of the meter. Where spiral flows are created by three dimensional elbows or rotary pumps, use additional distance
to dampen the effect. If a basket or Y-type strainer is used, place it 5 to 10 pipe diameters upstream of the meter to
dampen velocity profile distortions created by this design.
Installation
June 2016RCS-UM-00076-EN-04Page 6
◊ Do not install check valves or pressure reducing devices upstream of the meter.
◊ Valves immediately upstream of the meter should only be fully-open gate valves. Butterfly valves are acceptable if they
are 5 pipe diameters or more upstream from the meter. Downstream, fully open gate or butterfly valves can be used.
◊ Unweighted check valves should not be located closer than 3 pipe diameters downstream of the meter.
◊ Externally weighted check valves and pressure reducing devices should not be located closer than 5 pipe diameters of
the meter.
◊ When installing a compound meter and plate strainer of a size smaller than the pipe installation, to reduce the effect
of jetting caused by the increase in flow velocity, a minimum of 5 pipe diameters of pipe equal in size to the meter, is
required upstream of the meter. Additional length is required if a sharp contraction or an eccentric reducer, rather than
a concentric, tapered reducer is used.
Installing the Meter
Overall dimensions and laying lengths of each meter size are listed in the Recordall Compound Series Meter Product Data Sheet.
Review the dimensional requirements, choose an installation point in the piping, and proceed as follows:
1. Measure precisely the overall length of the meter with gaskets attached to the inlet and outlet ange connections.
2. Provide proper gap length in service piping.
3. Install meter in the pipeline so that the ow arrow on the meter housing points in the same direction as water ow.
4. With meter and gaskets in place, tighten ange connection bolts.
5. To relieve possible strain on the piping, position a meter support under the meter housing where appropriate.
Installation

Adapter Spacers
The 2" and 4" Compound Series meters are supplied in 15-1/4" and 20" lay lengths respectively. If you have an existing
compound meter with a lay length of 17" for the 2" size or 24" for the 4" size, a Flange Adapter Kit is available for each to
accommodate the difference. Mount the Flange Adapter to the outlet side of the meter.

COMPOUND METERS MUST OPERATE IN A COMPLETELY FILLED LINE AT ALL TIMES. THE DOWNSTREAM PIPING MUST
ALWAYS BE ARRANGED TO PROVIDE SUFFICIENT BACK PRESSURE TO MAINTAIN A FULL LINE AT THE METER. BY
ELIMINATING AIR IN THE LINE, AS WELL AS SUDDEN FLOW SURGES, INACCURATE REGISTRATION AND DAMAGE TO THE
TURBINE MECHANISM CAN BE AVOIDED.
Installation
June 2016RCS-UM-00076-EN-04Page 8
Performance Checks
Any valves or devices controlling the flow of water through a compound meter must always be opened and closed SLOWLY to
prevent shock loads that may damage the meter’s rotor assembly.
Complete the following checks to ensure that a compound meter is properly installed and operational:
• Slowly open the upstream valve to apply water pressure to the meter and check to see if there are any leaks. Tighten the
flange bolts as required.
• Perform a functional test of the meter. Slowly open valve on downstream side of the meter to evacuate any air that may
have been trapped in the service line. When air has been eliminated, increase demand flow rate by further opening the
downstream valve or valves. Observe the register for correct direction of flow. Continue to open the demand side valves
to a flow rate sufficient to open the valve assembly in the meter—a procedure which will start water flowing through the
turbo high-side rotor. The high flow pointer will now move in the proper direction. Now open all applicable service valves.
• Check the flow rate to verify that the flow does not exceed the maximum continuous duty specification. The rate of flow
can be quickly checked by timing the quantity registered through the meter in one minute.
Reading the Recordall Registers (and Encoder)
To determine the total reading for meter, the totals for both low and high flow must be added together.
1. Determine the low ow total by reading the register/encoder identied as low ow. Read only the moveable
number wheels.
2. From the high ow register, read both the number wheels and the sweep hand. Read the number wheels rst. Read
only the moveable number wheels. Note the position of the sweep hand, round the number down to the nearest
increment. Add the reading from the number wheel and the sweep hand together.
3. To determine the complete total ow, add the low ow and high ow totals together.

MAINTENANCE
This section is limited to information pertaining to the general maintenance of BadgerMeter Recordall Compound Series
meters. An exploded view of the meter, along with part numbers and descriptions, are provided in the Recordall Compound
Series Meters Parts List.
Accuracy Testing
The Compound Series meter can be tested for accuracy with a test meter or a test tank of known volume. A test plug is
provided on the meter. The low flow register is for recording the amount of water passing through the disc, or low flow side
of the meter. The high flow register is for recording the amount of water passing through the turbo, or high flow side of
the meter.
When testing at flow rates below the meter’s cross-over point, only the low flow test hand will move. Record the initial reading
(low flow odometer and low flow test circle). To determine the amount of water that has passed through the meter during
test, take the new reading from the low flow test circle. If more than one revolution of the test circle, take a new reading from
both the low flow odometer and the low flow test circle. The difference between the initial and final reading is then compared
to that recorded by the test meter or test tank.
When testing flow rates at or above the meter’s crossover point, the high flow and low flow register test hands will move.
This is because both sides of the meter, disc and turbo, operate simultaneously at these flow rates. The disc side of the meter
operates at all flow rates to keep the chamber free of debris that might enter the meter. Record the initial readings (high flow
odometer and high flow test circle, low flow odometer and low flow test circle). If less than one revolution of the high flow
test circle, record both the new high flow and low flow test circle readings. The amount of flow recorded by the high flow and
low flow test circles during test must be added together to determine the total flow through the meter. Compare this to that
recorded by the test meter or test tank.
If more than one revolution of the high flow test circle occurs, take new readings from the low flow odometer, high flow and
low flow test circles and add all complete high flow test circle revolutions to this. Once again, the amount of flow recorded by
the high flow and low flow test circles must be added together and combined to determine the total flow through the meter. This
is then compared to that recorded by the test meter or test tank.
A simplified alternative to recording the initial and final odometer readings on the high flow and low flow odometers, is to
record the number of complete revolutions of the test hand on the high flow and/or low flow test circles during test. This is
then added to the difference between the initial and final position of the test handson the test circles to determine the total flow
through the meter.
For correct testing procedures, and test volumes based upon meter flow rates, please refer to AWWA M-6 Manual. Starting the
test when the register test circle hands are on zero and operating the meters through complete revolution of the test circles
are desirable operating procedures to follow.
THE TEST HANDS OPERATE INDEPENDENTLY OF ONE ANOTHER. FOR EXAMPLE, DURING METER OPERATION AT FLOWS
BELOW CROSSOVER, THE LOW FLOW TEST HAND WILL REVOLVE WHILE THE HIGH FLOW TEST HAND IS STATIONARY,
ALLOWING HIGHER READINGS ON THE LOW FLOW ODOMETER ONLY.
Maintenance Equipment
The tools and equipment recommended for use in servicing and maintaining of Recordall Compound Series meters consist of
the usual complement of hand tools used by plumbers and mechanics.
Preventive Maintenance
The purpose of preventive maintenance is to ensure efficient operation and long life of the meter by detecting and correcting
any defect that might damage the meter or cause it to fail. Preventive maintenance consists of periodic inspection, accuracy
testing, and cleaning procedures.
Maintenance
June 2016RCS-UM-00076-EN-04Page 10
Periodic Inspection
• Visually inspect the meter for missing hardware, loose screws, broken or scratched register lenses or any other signs of
wear or deterioration.
• Verify that the meter is operating at the proper flow rate and pressure. A loss in pressure, coupled with a decrease in flow
rate, may indicate that the screen in the upstream pipeline—or the meter itself—is clogged with foreign material and
needs cleaning.
Cleaning
• Clean all dirt, grease, moisture or other foreign material from the exterior of the meter. After cleaning, rinse thoroughly
with water.
• In the event that system pressure has been reduced and the upstream filter or meter is clogged, the foreign material
must be flushed out. To flush the screen, open the cleanout plug and purge the foreign material with fresh water from
the service line. If cleaning the screen does not restore system pressure, the compound meter also should be flushed by
purging with fresh service water through the cleanout plugs located on the housing.

A typical installation would be equipped with drain and piping valves. To inspect or replace components of the High Flow
Turbo Head Assembly, close the upstream and downstream valves. However, if the installation does not have a drain valve,
proceed as follows to relieve pressure. See Figure 8 on page 12.
UPSTREAM AND DOWNSTREAM VALVES MUST BE CLOSED BEFORE ATTEMPTING TO REMOVE METER HEAD FROM
HOUSING. FAILURE TO DO SO CAN LEAD TO THE HEAD BEING "EJECTED" FROM HOUSING, CAUSING PERSONAL INJURY
AND/OR PROPERTY DAMAGE!
1. Loosen each of the High Flow Turbo Head Assembly bolts about 1-1/2 turns. Do not completely remove the bolts.
2. If the O-ring between the High Flow Turbo Head Assembly and the housing is secure and not leaking, pry the
Measuring Element Assembly loose by inserting a screwdriver blade where the head and housing join together.
BE SURE THAT ANY WATER COMING OUT OF THE METER HEAD DOES NOT SPRAY ONTO ELECTRICAL EQUIPMENT AND
CREATE A SHOCK HAZARD.
3. Allow the meter to drain and relieve internal pressure.
4. When pressure is relieved, remove the head bolts. Lift the Turbo measuring element assembly from the housing.
5. Follow the instructions for “Servicing the Chamber and Disc” on page 19.

Removing the Turbo Measuring Element Assembly from the Cover Plate
1. Remove the O-ring and cage seal.
2. Check for damage and clean or replace prior to reassembly.
3. To remove the measuring element from the cover, remove the calibration shaft seal plug and the lock screw.
4. Place the cover register-side down on a table or flat surface.
5. Lightly tap or press the calibration shaft from the wet side out of the bore in the cover (2", 3" and 4" only). Do not strike
or bend the calibration linkage.
6. The measuring element insert can be removed from the cover plate for service or replacement by removing the cage
set screws (quantity of one, except for the 6" size.)
7. Holding the cover plate in one hand, rotate the thermoplastic element counter-clockwise until the bayonet-like tabs
are aligned with open areas of the cover plate (2", 3" and 4" only).
8. Remove the element from the cover plate.
Removing the Magnet Carrier/Top Gear Set
1. To remove the magnet carrier from the measuring element insert, lift it o the stainless steel pin.
2. Check the condition of the magnet and gear on the magnet carrier for damage or wear. If signicant wear or damage is
present, replace the magnet carrier.
3. Remove the hold-down strap.
4. Check the condition of the transmission shaft gear for damage or wear. If signicant wear or damage is present, replace
the gear.
5. Lift the gear o the shaft.
Removing the Straightening Vanes/Nose Cone
The straightening vanes are an integral part of the upstream and downstream nose cone assemblies.
To gain access to them, remove the measuring element from the cover.
Removing the upstream nose cone provides access to the rotor, calibration ring and the transmission assembly.
To remove the nose cone:
1. Unscrew the upstream nose cone setscrew. For 2", 3" and 4" meters, slide the calibration linkage into the cage
insert stop.
2. Take hold of the nose cone/straightening vanes and turn them clockwise, thereby disengaging the calibration linkage
from the tab on the calibration ring and unlocking the bayonets of the nose cones from the cage (see Figure 12).
3. If the tab of the calibration ring has not disengaged the linkage, rotate the ring carefully by pushing the struts at the
interior of the element (between the straightening vanes and the rotor). Pull the nose cone assembly out from the
measuring element insert. For 6" meters, remove the transmission gear by lifting it o the shaft, noting the alignment
of the D-shaped bore with the at on the shaft (required to align for assembly).
4. Remove the retaining ring that holds down the calibration drive plate, located under magnet carrier magnet (see
Figure 8). Remove drive plate. Rotate calibration ring until pin clears slot of cage. Take hold of the nose cone/
straightening vanes and turn clockwise. Pull the nose cone assembly out from the measuring element insert. Remove
rotor assembly.
Removing the Calibration Mechanism
To disassemble the calibration ring assembly:
1. Remove the calibration shaft seal plug and unscrew the calibration shaft lock screw from the cover plate.
2. Remove the calibration shaft thrust washer and calibration shaft. Press the calibration shaft out of the cover plate
from below.

3. If a leak exists at this point in the disassembly of the meter, remove the calibration shaft O-ring. Before reinserting the
O-ring, apply a light coat of silicon grease to it.
4. Clean all parts.
To gain access to the calibration ring, the straightening vane/nose cone must be removed. See
“Removing the Magnet Carrier/Top Gear Set” on page 14 for instructions.
To remove the calibration ring from the nose cone assembly:
1. Align the ring slots with the bayonets of the nose cone assembly (located on inner ring of calibration ring).
2. Carefully lift the calibration ring from the nose cone assembly.
To reinstall the calibration mechanism, follow this procedure in reverse.

Reassembling the Calibration Mechanism
1. Align the pin on the perimeter of the calibration ring with the arrow tip located on the nose cone assembly (see
Figure 11 on page 15).
2. For 2", 3" and 4" sizes, install the calibration linkage into the cage with the larger hole to engage the calibration ring
tab, with the side of chamfered edge of the hole towards the nose cone assembly (see Figure 11 on page 15).
3. With the calibration linkage fully inserted to the cage stop, install the nose cone onto the cage and rotate it counter-
clockwise to engage the pin of the ring to the calibration linkage. The hole of the calibration linkage has to be aligned
onto the calibration shaft, engaging it fully so that the calibration ring cannot vibrate during operation.
4. Tighten the calibration shaft lock screw to securely hold the calibration ring in position.
After servicing or replacing the calibration mechanism, check the accuracy and calibration according to the instructions in the
Recordall Turbo Series Meter User Manual.

Inspecting the Rotor and Bearings
To inspect the rotor, remove the nose cone assembly from the measuring element insert as described in
"Removing the Magnet Carrier/Top Gear Set" on page 14.
Check the rotor worm and blades for signs of damage and wear. Also inspect the bearing bushings in the front and rear shaft.
If damage or wear has occurred, replace the part (see Figure 12). If water deposits are found, remove any mineral deposits
from the rotor blade surfaces, cage insert interior diameter, and nose cone vanes and mating surfaces.
Inspect the rotor bearing pins in the straightening vane and nose cone assembly for signs of damage and wear (see Figure 12).
The spherical end of the bearing pin must not show any drag lines and/or wear.

OTE:N Only highly-polished bearing pin ends provide a minimum of friction and optimal meter performance. Bearing
pins are an integral part of the straightening vane and nose cone assembly. Wear or damage would require the
replacement of this component.
Reassembling the Rotor and Bearings
1. Install the rear nose cone to the cage. See "Removing the Magnet Carrier/Top Gear Set" on page 14.
2. Place the rotor assembly with the worm gear side leading through the cage.
3. Place the rotor assembly on the rear rotor bearing pin, while tipping the assembly back so that the opening is up. See
“Removing the Calibration Mechanism” on page 14 for instructions on assembling the calibration rings with the nose
cone assembly.
4. Insert the front nose cone assembly partially onto the cage insert, engaging the bearing pin with the front bearing of
the rotor.
5. Tilt the measuring element insert assembly forth and back to see that the rotor now engages the bearing pins on the
straightening vane/nose cones and is free to rotate and slide.
DO NOT FORCE THE NOSE CONE ASSEMBLY INTO THE CAGE INSERT. BE SURE THAT THE ROTOR ENGAGES BOTH THE
FRONT AND REAR ROTOR BEARING PINS PRIOR TO PRESSING THE NOSE CONE ASSEMBLY FULLY INTO THE CAGE
INSERT.
