INSTALLATION
The following installation recommendations are adapted from the American Water Works Manual M6, and will result in the best meter life and accuracy.
Piping Conditions
It is recommended that the meter be installed with at least ten (10) diameters
of straight pipe upstream and five (5) diameters downstream from elbows, tees,
crosses, valves, and other fittings. If less straight pipe is available, or if
debris are likely to go through the meter, installation of a standard plate-
type strainer directly upstream is recommended. If a basket-type strainer is
used, it should be located at least five diameters upstream. Avoid conditions
of trapped air or partially-filled pipe. This can occur when there is low flow
and open discharge near to the meter.
Flanges
The WJ meter is compatible with any standard 150 lb. ANSI drilling, flat or
raised face. Take care that gaskets (included) do not protrude into the meter
due to misalignment. Adhering the gasket to the meter flange with gasket
adhesive is a good practice that will aid installation.
Orientation
WJ-Series are all-position meters, and can be installed horizontally or
vertically. Horizontal with register facing up is recommended when possible.
MAINTENANCE AND REPAIR
|
CAUTION: Before breaking the tamperevident seal on your meter, be sure
that you are in compliance with any regulatory requirements (if applicable).

Adding Reed Switch
For the contacting head option, WJ meters use a metermounted reed switch to provide a two-wire dry contact. To add a reed switch in the field, remove one of the rubber plugs from the side of the register housing and slide the reed switch assembly into the housing in the direction of the dial with the desired pulse rate. Lock in place with the rivet and pin (see page 3).
Note: If changing the pulse rate, you need to first remove the reed switch from the position it is in. In doing so, the small plastic rivet & pin will be damaged and should not be reused. Have a replacement plastic pin & rivet before beginning. If you do not have a spare, contact factory for a replacement (see page 3 for part reference).
Changing the Pulse Rate
When changing the pulse rate, you must first remove the existing reed switch (see note above).
-
Choose desired pulse rate and switch position.

10,000| x1,000 - Remove the rubber plug from the other hole and move it to the position the reed switch was removed from.
- Insert the reed switch assembly into the side of the register housing in the direction of the dial with desired pulse rate.
- Lock in place with rivet and pin.4
Register Removal
Clip and remove the copper security wire from the security pin. Remove the security pin that holds the lid in place, twist the lid and lift it off. Lift the register free from the meter, noting orientation.
Recalibration
For meters used for revenue-billing purposes, some states require periodic
calibration checking. This type of turbine meter is most commonly checked
every four years. Testing may be done by a local mobile meter service or in a
private or municipal meter shop. Changes in calibration should be made at an
authorized meter shop.
Turbine Insert Replacement
The entire turbine insert comes out as a unit without removing the meter from the pipe. Carefully note position and retain parts for reassembly.
- Remove the lid and register as described.
- After relieving pressure inside the meter, remove the four flange hex-screws and washers.
- Lift the flange and insert out in one piece, rocking gently to break the seal.
- Remove the four retaining ring screws, and lift the retaining ring and flange off the turbine insert.
- Remove and replace the large O-ring around the top opening of the meter body.
- Reassemble the retaining ring and flange on top of the new insert. Be sure the alignment notch in the retaining ring is directly above the screw in the insert’s top plate.
- Replace the entire mechanism in the meter body with the drilled screw head in the same corner as the security pin.
- Replace the lid with a twist of the wrist, insert the security pin in the tiny hole in the retaining ring, and thread the security wire through the screw head and the security pin. Affix lead seal and crimp.
