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 are not required on the
4-inch meter. The meters
require 2 pipe diameters
straight run before and after
the meter. The all-mechanical
sensing system directly drives
the pointer and remote signaling devices. They handle
shocks or flow surges beyond
their rated capacities.
The swinging vane can be
manually operated with a factory supplied wrench to verify
or adjust switch points, or to
free the vane should it become
lodged by debris in the fluid.

CALIBRATION
All flow meters are individually calibrated on fluids suitable to maintain
the stated accuracy for viscosities
up to 3000 SSU (650 Centipoise).
We also compensate for specific
gravity. For NIST Traceability please
consult factory.
CONSTRUCTION MATERIALS
The meter body, moving parts,
and seals are offered in a variety
of materials to suit a wide range of
applications: water, synthetic and
petroleum based oils, paint, some
corrosives, solvents, and air and
gases. The flowmeter body is made
up of the “center section” which is
where the moving parts are. Sometimes it is cost effective to match this
to other materials for the in and outflow sections of the meter body and
flanges. See selectiohns in the “How
to Order” section. Please consult the
factory for compatibility of materials
with your application.

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