Flow Sensor Sizing
FS050P, FS075P, & FS100P flow sensors have an operating range 2 to 20 ft/sec (water velocity in
pipe).
FS150P, FS200P, FS300P, FS400P, FS100B, FS150B, FS200B, FS350B & FS350SS flow sensors have
an operating range 1/2 to 30 ft/sec (water velocity in pipe).
Select a flow sensor size based on the smallest station flow rate and the largest system flow rate.
If a single flow sensor is outside the operating range of a single sensor a dual bypass flow sensor
system is recommended.
