Abstract

PURPOSE: To reduce the fault occurrence, by giving control to the amplifier via the integrator so that the sum may be zero between the half-wave rectified current of the calculating capacitor and the dielectric constant detecting capacitor receiving the supply of the output of the voltage control amplifier connected at the middle point of the secondary winding and that of the comparing capacitor and volume measuring capacitor connected to the secondary winding of the power source transformer.
CONSTITUTION: The output currents of the fuel volume measuring and comparing capacitor 3 and 4 connected to the secondary winding of the power source trnasformer 1 are supplied to the integrator 13 after the rectification through the half-wave rectifying elements 9 and 10. At the same time, the output currents of the calculating capacitor 5 and the dielectric constant detecting capacitor 6 which receives the application of the output of the voltage control amplifier 11 connected to the middle of the secondary winding are supplied to the integral amplifier 13 after the rectification through the half-wave rectifying element 12. The voltage control amplifier 11 is controlled with the output Vc so that the sum may be zero among the currents supplied to the amplifier 13. Thus the weight of fuel can be obtained from the output Vc. The mechanical driving part is excluded compared with the conventional device using a servo mechanism, thus reducing the fault occurrence and enhancing the economical properties.
