The rugged, low-cost FPR100
Series sensors feature a one-piece
composite rotor, sturdy unibody
construction, ceramic shafts, and
superior sealing. The FPR110
sensors, with bright orange spinning
rotors, provide visual indication
of flow only. The FPR120 Series
features visual indication and
an adjustable 0.5 A @ 110 Vac
SPDT mechanical flow switch. The
FPR130 Series has visual indication
and a square-wave pulse output
for use with remote ratemeters/

totalizers, such as the DPF700
Series meters.

For panel mounting, all
polypropylene units come with
mounting ears that accept #8
self-tapping screws; all brass units
come with mounting holes that
accept #8-32 UNC-2B screws.
For all FPR100 sensors, incoming
flow can be directed to either port;
a minimum of 8 inches of straight
inlet pipe is required. Filtration of
150 microns is recommended.
