Continuous level measurement for grease separator |
摘要 |
An automatic draw-off grease interceptor 10 includes a separation tank 12 defining a chamber 40. An inlet 24 delivers an effluent stream of grease and water into the chamber which separates into a thicken layer of grease atop a water layer. A pump 70 is included for pumping grease from the chamber when the grease has reached a predetermined level 120. A conductive probe 90 extends vertically in the separation tank 12 from a location above the upper surface of the effluent to a location below the predetermined level 120. An R/C oscillator circuit 112 continuously measures the amount of water in the chamber by measuring the capacitance between the probe and a wall of the tank. A controller 116 actuates the pump in response to the R/C oscillator circuit measuring a capacitance corresponding to an amount of water in the tank when the grease layer reaches the predetermined level.
