Abstract:
1. An ozone-based disinfecting device comprising a mixer having a generally hollow body with a water inlet for water under pressure; a spray nozzle for generating a generally conical spray of water introduced by way of the water inlet; a contact chamber communicating with a gas inlet for ozone rich gases; an outlet aperture from the contact chamber with the outlet aperture being coaxial with the spray nozzle and spaced apart therefrom, and a flow sensing device for sensing the extent of flow of water through the spray nozzle, wherein the flow sensing device is an electronic flow sensing device for sensing vibration caused by a flow of water through the mixer and comprises a piezoelectric sensor and an appropriate associated circuit for generating a signal indicative of the rate of flow of water through the mixer, wherein the piezoelectric sensor is embedded in a settable material and has the general shape of a disc that has a thin smaller diameter compressible disc adhered concentrically to both surfaces of the sensor disc with the outer diameter of the piezoelectric sensor firmly embedded in the settable material and wherein a small hole in the center of one disc provides for the settable material to contact the piezoelectric sensor in the central region on the one side thereof.
