Flotect® V6 Flow Switch is engineered to specifically

monitor liquid, gas, or airflows.  Operation is simple

and dependable with no mechanical linkage as the

flow switch is  magnetically actuated.

The lower body holds the flow vane and one magnet,

which  controls the switch actuating magnet

 in the separate upper housing. In most applications

 the switch is normally off with the pipeline flow forcing

the vane against the vane spring.

As the flow decreases the vane spring pushes

back the vane, actuating the switch to signal

an alarm or shutdown.  Tees are available

for installation in pipelines from 1/2" to 2", with bushings

added the unit is easily adapted to 1/4" and 3/8" piping.

Possible Applications:

 

  • Protects pumps, motors and other equipment against low or no flow
  • Controls sequential operation of pumps
  • Automatically starts auxiliary pumps and engines
  • Stops liquid cooled engines, machines  when coolant flow is interrupted
  • Shuts down burner when air flow through heating coil fails
  • Controls dampers according to flow
  • Signals alarm when emergency shower in use
