Abstract

A sensor apparatus for a grease trap (2) comprising a sensor body (20) arranged to be submerged in effluent within a grease trap, said sensor body incorporating a plurality of first sensors (30) adapted to distinguish between air, water and fat/oil/grease, at predetermined vertical positions within the grease trap, in use, and a transmitter for wirelessly transmitting data from said plurality of first sensors (30), the apparatus further comprising a receiver (40) receiving data from said plurality of first sensors and a processing means (50) for monitoring operation of the grease trap in response to said date received from said plurality of sensors.

Claims (12)

  1. Claims

  8. 8. A sensor apparatus as claimed in claim 7, wherein said sensor body incorporates a plurality of said second sensors adapted to determine the temperature of the effluent at different vertical positions within the grease trap, in use.
  9. 9. A sensor apparatus as claimed in any preceding claim, comprising a first sensor body incorporating a plurality of said first sensors and a transmitter for transmitting data therefrom to said receiver and a second sensor body incorporating a plurality of said first sensors and a transmitter for transmitting data therefrom to said receiver, said first and second sensor bodies being mounted on a support frame adapted to be located within a grease trap such that the first sensor body is located in an upper region of said grease trap, in use, and said second sensor body is located in a lower region of said grease trap, in use.
  10. 10. A sensor apparatus as claimed in claim 9, wherein said support frame is adapted to adjust the distance between said first and second sensor bodies to adjust the height of the first sensor body.
  11. 1 1 . A sensor apparatus as claimed in any preceding claim, wherein said processing means is adapted to control a skimming device for removing FOG from the grease trap as a function of the data received from said plurality of first sensors.
  12. 12. A grease trap for removing FOG from waste water comprising a tank having at least one waste water inlet for passing waste water into an inlet region of the tank, at least one waste water outlet for draining waste water from an outlet region of the tank, and a sensor apparatus as claimed in any preceding claim, wherein said sensor body of said sensor apparatus is located within the tank such that said plurality of first sensors can detect the presence of air, water and FOG are predetermined heights within the tank to determine the thickness of the layer of FOG in the tank and the transition between water and FOG within the tank.
