LPF: LOW PRESSURE FLOWMETER ... the flow meter designed to measure the instantaneous flow of low pressure fuel or urea injectors.

The system LPF (Low Pressure Flowmeter) is designed to measure the instantaneous flow injectors in low-pressure gasoline indirect injection systems. It has also been successfully adapted for use in the urea injection applications.

  • The LPF generates the inlet pressure of the injector which ensures a high degree of stability of the injection.
  • Each injection is measured in mass to 0.1 mg allowing a measure of the standard deviation of the injector.
  • It is designed to give you precise values for the measurement of dynamic flow, opening and closing delays, static flow measurement for a long injection at the operating frequencies of the injector.
