Abstract
Disclosed is a sensor for detecting flow quantity of fuel supplied to a fuel injection system based on an idea that the flow quantity of fuel supplied to a fuel injection system is detected by means of detection of a displacement of a spill-ring. This sensor is provided with a detection member connected with a spill-ring of a fuel injection system, a coil assembly consisting of a coil for detecting the displacement of the spill-ring which is fitted to one end of a bobbin which is arranged to face with the detection member but not to contact the detection member, the one end of the bobbin being arranged to face with the detection member, and a coil for temperature compensation, the two coils being arranged side by side along the bobbin with a predetermined space therebetween, and a member for holding the coil assembly and for fitting the coil assembly to the fuel injection system.
