Ice fraction sensor

An optical ice fraction sensor comprises a flow path 1 defined by pipe walls 4 in which an ice-containing medium can flow, an optical emitter 2 at a first end of the flow path 1 and an optical receiver 3 at a second end of the flow path 1. In use, a light path 1 extends between the emitter 2 and rec...

More Information
Summary:An optical ice fraction sensor comprises a flow path 1 defined by pipe walls 4 in which an ice-containing medium can flow, an optical emitter 2 at a first end of the flow path 1 and an optical receiver 3 at a second end of the flow path 1. In use, a light path 1 extends between the emitter 2 and receiver 3 and at least a portion of the light path is parallel to the flow path 1. Ice-containing medium flows from inlet pipe 7, along the flow path 1 and leaves via outlet pipe 8. The ice fraction sensor can be used for measuring or monitoring the ice fraction of the ice-containing medium present in the flow path. The ice-containing medium may be ice slush or an ice-containing beverage medium. A reflector (11, Fig 5) may be provided at a second end of the flow path and the emitter 2 and receiver 3 may be provided in a single unit at the first end of the flow path.
