User Manual SCOPE OF THIS MANUAL This manual contains installation, operation and maintenance procedures for the Badger Meter® Recordall® Compound Series meters with magnetic drives. To ensure efficient operation of the meters, read and understand 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.
Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" INSTALLATION Procedures for installing Recordall Compound Series meters are essentially the same for all meter sizes. Any special instructions required for the installation or connection of accessory devices such as AMR/AMI technologies or strainers is provided in the literature for those devices. Figure 1 shows a recommended meter installation.
User Manual ◊ 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.
Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" 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.
User Manual 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.
Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" MAINTENANCE This section is limited to information pertaining to the general maintenance of Badger Meter 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.
User Manual 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.
Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" SERVICING PARTS AND ASSEMBLIES When the performance of a compound meter indicates a need for servicing, refer to the following instructions pertaining to removal, inspection and installation of service parts and assemblies. Also see the Recordall Compound Series Meter Parts List for part numbers of replaceable components and correct ordering information. If satisfactory repair cannot be made, contact Badger Meter.

Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" 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.
User Manual 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.
Recordall® Compound Series Meter, Sizes 2", 3", 4" and 6" 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).
User Manual 6. Press the nose cone assembly fully into the cage insert and turn it counter-clockwise, catching the calibration linkage in the slot. 7. Check to see that the rotor spins freely. If it does not, remove the nose cone assembly and repeat the procedure. 8. Install and tighten the nose cone assembly setscrew. 9. Holding the cover plate in one hand, align the thermoplastic cage bayonet-like tabs with the slots in the cover plate (2", 3" and 4" only). 10.

Remove the screws holding the bottom plate on the cover assembly. 2. Remove the bottom plate. 3.
User Manual Valve Assembly Removing the Valve Assembly With the cover assembly removed, the valve assembly is exposed for service. 1. Remove the lock pawl (see Figure 14). 2. Turn the valve assembly counter-clockwise to unscrew it from the housing. 3. Lift the valve assembly out of the housing. Replacing the Valve Assembly If any portion of the valve assembly requires replacement, we recommend replacing the entire valve assembly. 1. Drop in the new assembly. 2.
Reinstalling the Cover Assembly Badger Meter recommends that a new O-ring be used after each teardown and reassembly of the cover assembly. To assure a tight seal, make sure O-ring is positioned correctly on the housing and that the O-ring and cover assembly are clean and free of dirt or residual traces of old O-ring material. If necessary, use silicone grease to help retain the O-ring and to serve as a lubricant in reassembling it to the housing.
