Description

The Signet 2517 Paddlewheel Flow
Sensors offer added strength and
durability of brass construction for a
variety of applications. The wide flow
range of 0.5 to 6 m/s (1.6 to 20 ft/s)
allows the sensor to measure liquid
flow rates in full pipes and can be
used in low pressure systems. Fluo-

sensor signal allows for remote to­talization when coupled with the 8150
battery operated Flow Totalizer. Sen­sors can be installed in DN 40 to DN
600 (1.5 to 24 in.) pipes using the 1.5
inch (or ISO 7/1-R 1.5) threaded pro­cess connection. The sensors are also
offered in a hot-tap configuration with
a bleed valve for installation in pipes
up to DN 900 (36 in.) and allows for
servicing without process shutdown.

Application Tips:

• For systems with com­ponents of more than
one material, the maxi­mum temperature/pres­sure specification must
always be referenced to
the component with the
lowest rating.

• Use the Conduit Adapter
Kit when used in outdoor
environments.

• The 2517 can be used in
intrinsically safe areas
using an approved bar­rier between the sensor
and instrument.
