Georg Fischer 2100 Specifications

Signet 2100 Turbine Flow Sensor

Features

• Operating range of 0.38 to 38 lpm (0.10 to
10 U.S. gpm)

• Non-magnetic turbine

• Union ends for various connector types

• End connector kits for rigid or fl exible tubing
or DN15 (½ in.) pipe

• PVDF & ceramic wetted parts provide superior
chemical compatibility

• For use with both clear and opaque fl uids

• Small and compact design

Engineered specifi cally for small pipe diameter
applications, the Signet 2100 Turbine Flow Sensor
provides accurate readings in two fl ow ranges:

0.3 to 3.8 lpm and 3 to 38 lpm (0.1 to 1 gpm and

0.8 to 10 gpm).

The injection-molded PVDF body and ceramic bearings
provide excellent chemical compatibility and long
service in dosing and batching applications. Union
piping and tubing connections along with removable
NEMA 4X electronics allow for easy assembly and fi eld
replaceability. The 2100 can be used with DN8 (¼ in.),
DN10 (3/8 in.), DN15 (½ in.) tubing, or DN15 (½ in.) piping
for simple installation. End connections are available in
PVDF for hose barbs, fusion socket or IR/butt fusion, and
in PVC for socket or NPT thread.

• 4.6 m (15 ft) cable

• Features removable electronics that installs
from either side of the sensor

Applications

• Chemical Addition

• Textile Dyeing
