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, switches and transmitters.
The body is aluminum with nylon.
Internal moving parts are stainless steel. Seals are Buna-N.
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.

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

Maximum ambient temp: 150°F
(65°C)
Series SN max. operating pressure:
300 PSI (20.69 BAR)

INSTALLATION
Flow monitors mount in-line and are
typically supported by rigid pipe.
1
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.
