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 in-
stalled with at least ten diameters of straight pipe upstream
and five 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 stan-
dard 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.
Position. WJ-Series are all-position meters, and can be in-
stalled horizontally or vertically. Horizontal with register facing
up is recommended when possible.
