DESCRIPTION
These variable-area meters position an orice over a tapered shaft
to establish ow rate. Mounting is
in-line and in any position. Straight
pipe runs before or after this
monitor are not required. The
all-mechanical sensing system
directly drives the pointer and
remote signaling devices. Readout
is visual with a pointer and scale
combined with switches and a
4-20 mA transmitter.
CALIBRATION
CONSTRUCTION MATERIALS
This meter is congured for water.
Brass/polysulfone body with brass
and 316 SS internal moving parts
and Buna-N seals.
LINE CONNECTION
The ports are threaded, can be
NPT or SAE straight-threads from
1/8 to 3/4 inch. Metric threads such
as BSPP or BSPT are also available. The upper port (inline) has a
maximum capacity of 2 GPM and
the lower port (offset) is standard for
the remaining ow rates.
All ow meters are individually
calibrated for water. For NIST
Traceability please consult factory.
NOTE: This is a simplied model code and does not include standard
options like other materials of construction, internal moving parts, seals,
anges, pressure ratings, multiple switches etc. which can be found in
other catalog sheets.

Fluid ow causes a
spring-loaded piston
A having a circular
opening at its center B
to move along the axis
of a precision-tapered
shaft C. This creates a
variable orice in direct
proportion to the ow
rate. The piston is mechanically linked to the
readout pointer D and
actuates switch E or a
pot driven trans-mitter
(not shown).
