Definitions

  • the capacitive sensors 30 of the sensor arrays 20,22 are sufficiently sensitive to permit the measurement of FOG concentration so that the sensors 30 can determine if the FOG retained in the tank and above a particular depth is at an appropriate concentration to warrant extraction from the tank for further processing
  • Each sensor array 20,22 continuously reports its measurements by means of an inbuilt wireless transmitter, such as a Bluetooth radio beacon, that may be received by any correctly configured receiver 40.
