GENERAL INFORMATION
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 total-
izing, pacing of electronic metering pumps, and water treat-
ment 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 replace-
ment. 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.
