WFS
Mechanical wind vane switch RHEASREG
monitoring of gaseous, non-aggressive media. The flow sensor is used as a flow controller or air flow monitor in air conditioning ducts, in air intake
or exhaust devices of ventilators or electric heating registers (also for contaminated, oily air).

Contact 1 - 3 breaks when flow rate drops to the preset value.
Simultaneously, contact 1 - 2 closes and
can be used as signal contact.
Device is factory-set to the minimum switch-off value,
which can be increased by turning the range adjusting screw clockwise.

Min. smoothing distance = 5 x duct diameter upstream and downstream of vane.
For airspeeds > 5 m ⁄ s, vane is to be trimmed at the marked spots.
Thereby the minimum switch-off value increases
to approx. 2.5 m ⁄ s and the minimum switch-on value
to approx. 4 m ⁄ s.
