Hall Effect Flow Switch Model Q-15
Hall Effect Flow Switch
Model Q-15 is the most sensitive paddle type flow switch available. It utilizes Hall Effect technology and is programmed for the highest sensitivity.
Model Q-15 comes standard with 8 conductor modular cable and Cat 3 modular connector. Other cable/connector combinations available upon special order.
Max. flow may be five times normal flow.
Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element.
Very low pressure drop - typically less than 1.0 psig at normal flow rate.
Small size and low profile provides easy mounting in crowded installations.
Switch employs magnetic coupling.
