Signallers are designed for remote signalling of increase or decrease of air velocity in the duct relative to one fixed value (setpoint) by issuing a corresponding relay signal. The operating principle of the device is based on the effect of formation of a chain of regular vortices (Karman's track) in the viscous gas flow in the wake of a stationary streamline body.
