DESCRIPTION
CONSTRUCTION MATERIALS
These are variable area meters
with a spring biased semi-circular
vane that opens wider with more
ow. They are installed in-line in
any position. Straight pipe runs
before or after the meter are not
required. The simple mechanical
connection directly drives
pointers, dials and cams. They
are very hardy. Readout is visual
with a pointer and scale combined
with either switches or a 4-20 mA
transmitter.
The materials of construction are
wetted parts of brass and Nylon
with 316 SS internal moving
parts and Buna-N seals.

Ports are threaded and can be
NPT (1/4 to 3/4 inch) or SAE
straight thread (1/4 to 5/8 inch).
Metric threads such as BSPP or
BSPT are also available.

CALIBRATION
All ow meters are individually
calibrated for water. For NIST
Traceability please consult factory.
NOTE: This is a simplied model code and does not include standard
options like other materials of construction, internal moving parts, seals,
anges, pressure ratings, multiple switches etc. which can be found in
other catalog sheets.

Fluid enters at A, passes
around the semi-circular
vane B. exits at outlet C.
The vane resists the ow
because of the spring D.
The further the vane is
pushed the larger the
passageway E becomes.
The vane shaft turns to
operate the pointer F and
remote signal devices
such as the switch G or
transmitter (not shown).
