Flow Switch
1 inch Model Q-10

One Inch Flow Switch

FLEXIBLE DESIGN:

Model Q-10 can be provided with three factory adjustable parameters which provide performance flexibility to meet a multitude of applications:

  • Paddle Area
  • Paddle Length
  • Paddle Stiffness

Responds to fluid flow only, independent of line pressure and temperature.

Max. flow may be five times normal flow.

Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element.

Small size and low profile provides easy mounting in crowded installations.

Very low pressure drop – typically less than 1.0 psig at normal flow rate.

Quick response.

Available with NO, NC or SPDT Reed Switch

Switches 5VDC to 240VAC.

Switches resistive and light inductive loads.

Switch employs magnetic coupling.

INDUCTIVE LOADS

Switch contacts have been tested with small relays and 30A J-C relay inductive driving coils at 120/240VAC to 500,000 operations without failure.

Model Q-10N can also be fitted with a SPDT Gold Cross Bar Switch for computer/PLC interface.

NOTE: Model Q-10N employs magnetic coupling between bending blade and switch body. Magnetic particles can accumulate on and around magnetic housing which may affect proper operation. Please conduct appropriate fluid magnetic particle evaluation and operational tests prior to and during installation and use.
