Danfoss’ Flow Sensor Series is designed to protect
personnel and property in case of hose failure in
compliance with Federal Safety Regulations. Flow Sensors
are intended for use with compressed air.

• Automatically shuts off air flow to
ruptured hose
• Automatically resets after failure
correction
• Compact design, economical, tamperresistant
• Reduces risk of injury or damage from
hose whip
• Operates in any orientation

HOSE
Flow Data: The graph above indicates the minimum inlet pressure for various hose
lengths. Each Flow Sensor has a shut-o昀昀 昀氀ow rating dependent upon inlet pressure.
The length of hose and 昀椀tting size are critical in the proper operation of the valve. For
example, with the B8FS50F8 Flow Sensor, the hose I.D. must be 1/2” using only 1/2” pipe
thread end 昀椀ttings. Thirty feet of hose requires at least 20 psig inlet pressure; 昀椀fty feet of
hose requires at least 28 psig inlet pressure; and seventy-昀椀ve feet of hose requires at
least 36 psig inlet pressure. Inlet pressures lower than those indicated on the curves
above will not guarantee protection in case of hose failure. Valve shut-o昀昀 occurs only
when flow exceeds the flow rating for the inlet pressure.
If hose lengths greater than 75 feet are required, a 1/2” size or larger Flow Sensor must be
installed on the inlet end of each 75-foot section, and a correspondingly higher inlet
pressure must be supplied for proper operation of the Flow Sensor to assure safety.
