WJ-Series turbine meters are dry-register mechanical totalizers that offer accurate, economical reading of high flows with low pressure loss. The horizontal-axis turbine drives a vertical shaft, which is magnetically coupled to the sealed register.
In addition to mechanical totalizing, registers can be equipped with magnetic pulse reed sensors well suited for remote totalizing, pacing of electronic metering pumps, and water treatment applications.
Bodies are manufactured of tough cast iron and epoxy-coated for protection. Tungsten steel shafts and jewel bearings further enhance the durability of these meters. Simple removal of the top flange brings out all parts for inspection, repair, or replacement. The meter has a tamper-evident seal to call attention to unauthorized access.
Compatible Seametrics controls include the PT35 pulse timer, the PD10 pulse divider, and the PS40 pulse splitter for running multiple pulse-responsive devices (e.g. pumps, counter timers and remote totalizers) with a single WJ meter.

Dimension
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.
