The FTB-630 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.
