Flow Switch Heavy Duty Model Q-5


The Strongest Flow Switch Brass

Designed for extreme, long-term reliability.

Detects and signals flow change.

Continuously adjustable while in operation.

For use in particle contaminated fluids.

Multiple quick change paddles (and continuous spring adjustment) provide an incredibly wide operating range of flow rates and viscosities.

Use with an intrinsically safe relay allows Model Q-5 to be used in hazardous areas.

Maintains calibration limits when subjected to reasonable line hydraulic hammer or surge pulses.

Calibrated independent of line pressure and temperature.

DPDT model available per request.
