DESCRIPTION
These are variable area meters
with a spring biased semi-circular
vane that opens wider with more
flow. 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, switches and
transmitters.
Readouts
The flowmeter has outputs both
visual and electronic. Visual
displays are either pointer (with
inscribed scale) or numeric
(digital LCD). Electronic outputs
can be mechanical switch
closure, 4-20 mA analog or
both (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.

CALIBRATION
All flow meters are individually
calibrated for fluids with the
viscosity you specify (up to
3000 SSU/650 Centistokes).
We also compensate for your
fluid's specific gravity. For NIST
Traceability please consult
factory.
CONSTRUCTION MATERIALS
The meter body, internal moving
parts, and seals are offered in a
variety of materials to suit a wide
range of applications, such as:
water, synthetic and petroleum
based oils, paint, corrosives and
solvents. See selections in the
“How to Order” section.
LINE CONNECTION

C
D

A

F
G

B

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 pressure
drop. The vane shaft turns
to operate the pointer F and
remote signal devices such
as the switch G.

Ports can be threaded or flanged.
See selections in the “How to
Order” section.
