DESCRIPTION
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,
switches and transmitters.
CALIBRATION
All ow meters are individually
calibrated for uids with the
viscosity you specify (up to 3000
SSU/660 Centistokes). We also
compensate for your uid’s specic
gravity. For NIST Traceability
please consult factory.

Readout accuracy, full scale: ±2%
Switch repeatability 1% of actual
ow.
E
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. This minimizes the
pressure drop. The vane shaft turns
to operate the pointer F and remote
signal devices such as the switch G.
FLOW & PRESSURE DROP
Units impose a pressure drop that increases with ow from 1.9 to 3.8 PSI.
