The measuring system adopts the scattering principle of the infrared light source which is commonly used in the world. When the infrared light emitted by the emitter passes through the flowing oil sewage, the oil particles in the sewage scatter the infrared light. Two infrared receiving tubes are installed at the same axis of the light source to test the transmission and scattering components of the infrared light after passing through the oil and water, and then the oil particles are transported. The output signal is sent to CPU after filtering, amplification and A/D transform.
