The Series V6 Flotect® Mini-Size Flow Switches are surprisingly compact, and
specically engineered to monitor liquid, gas, or air ows. Time tested in thousands
of pipeline installations and processing plants around the world, this Series is
Weatherproof, designed to meet NEMA 4 and Explosion-proof (listing included in
specications). Tees are available for installation in pipelines from 1/2˝ to 2˝ (12.70 to
50.80 mm). With bushings added the unit is easily adapted to 1/4˝ and 3/8˝ (6.35 and
9.53 mm) piping.
FEATURES/BENEFITS
• Unique magnetically actuated switching design gives superior performance
• Features a free-swinging vane which attracts a magnet within the solid metal switch
body, actuating a snap switch by means of a simple lever arm with no bellows,
springs, or seals to fail
• Leak proof body machined from bar stock
• Electrical assembly can be easily replaced without removing the unit from installation
Paddle
so that the process does not have to be shut down
• Choice of models in a tee with calibrated vane or eld adjustable trimmable vane
Flow Switches,
• Easy installation with simple pipe insert via tee and simple electrical switch
connections
• High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138
bar) with the 316 SS body
• Low ow model offers eld adjustable set point
APPLICATIONS
• Protects pumps, motors and other equipment against low or no ow
• Controls sequential operation of pumps
• Automatically starts auxiliary pumps and engines
• Stops liquid cooled engines, machines and processing when coolant ow is
interrupted
• Shuts down burner when air ow through heating coil fails
• Controls dampers according to ow
• Signals alarm when emergency shower or eyewash station in use
