DESCRIPTION
These variable-area flow meters
have a spring-loaded swinging
vane. Mounting is in-line and in
any position. Straight pipe runs
before or after the meter are not
required. The all-mechanical sensing system directly drives
the pointer and remote signaling
devices.
CALIBRATION
All flow meters are individually calibrated for fluids with the viscosity
you specify (up to 3000 SSU (650
Centistokes). We compensate
for your fluid's specific gravity. For
NIST Traceability please consult
factory.
OUTPUTS
The flowmeter has outputs both
visual and electronic. Visual
displays are either pointer (with
inscribed scale) or numeric. Signal
outputs can be mechanical switch
closure, 4-20 mA analog or both

style control box.

(for signal redundancy). The
switches can be general purpose
or rated for hazardous locations
(all classes, groups and divisions). The 4-20 mA transmitters
are Intrinsically Safe if used with
approved barriers.
CONSTRUCTION MATERIALS
These flowmeters have plastic
bodies, a wide variety of metal
internals, and fittings. They are
ideally suited to monitor flows
of such fluids as corrosive liquids, seawater, deionized water,
acids,caustics, and plating solutions. See selections in the “How
to Order” section.
LINE CONNECTION
Threaded units have a 7/8-14 inch
SAE ports. Adapters are used to
offer NPT port connections both
male and female and in plastic
or 316 SS (see “How to order”
section). One inch diameter Van
Stone flanges are offered in PVC.

E

Fluid enters at A, passes
around the semi-circular
vane B, exits at outlet C.
The vane resists the flow
because of the spring D.
The further the vane is
pushed the larger the
passageway E becomes.
This minimizes the
increase in pressure drop.
The vane shaft turns to
operate the pointer F and
remote signal devices
such as the switch G.
