Unique Design
The FW1000 Series are minimally invasive,
low-cost segmented wedge flow sensors. The
segmented wedge element provides a simple
and reliable restriction for sensing flow as related
to pressure differential. The FW1000 design allows
users to install the meter in any full pipe orientation
(horizontal, vertical or inverted). It is compact and
rugged measuring less than 254 mm (10") long and
89 mm (3
1
⁄2") wide, with a flanged mounting base for
simple installation. This series is offered with several
ranges of calibration to accommodate the
requirements typical to process water applications.
Three standard NPT port sizes are available to
accommodate installations. The standard unit can
also be converted to a 1 to 10 Vdc output in the field.

Comes complete with operator’s manual.
For units with 4 to 20 mA output, in place of the 0 to 5 V output, add “-I” to the model number,
no additional charge.
Ordering Examples: FW1210, PVC wedge flowmeter,
rate meter and TX4-100, multi conductor wire, $519 + 289 + 35 = $843.
FW1315, PVC wedge flowmeter,
$555 + 40 = $595.
