Abstract: 1479752 Measuring liquid level electrically SIMMONDS PRECISION PRODUCTS Inc. 20 June 1974 [25 June 1973] 27309/74 Heading G1N [Also in Division H3] A capacitance fuel tank gauge includes a pair of diodes positioned within the probe to rectify the capacitance signal before transmission to the measuring circuit. The probe 25 comprises an inner electrode 10, on which is insulating layers 11 and 13 and an earthed conducting layer 12 patterned to provide a linear output, and an outer electrode 16. Two diodes 17, 18 positioned within the electrode 10 form part of the probe 25 which is supplied with A.C. from a frequency and amplified stabilized source 24, the probe output being connected to the inverting input of integrating amplifier 26 whose output is connected to meter 23. In order to balance out from the probe output the empty tank output diodes 17, 18 are connected with diodes 47, 48 in a bridge circuit 55, diodes 47, 48 and capacitor 45 being connected via potentiometer 43 to tap 44 on the excitation transformer 32. Thus with 43 suitably adjusted capacitor 45 and diodes 47, 48 apply a D.C. signal to the inverting input of amplifier 26 of opposite polarity to that of the empty tank current from the probe to balance the latter. Since the same voltage is used for capacitor 45 and probe 25 the effects of frequency and amplitude changes on the initial adjustment are negated. The circuit is such that the system is insensitive to stray capacitance and allows the use of single wires instead of coaxial cables.
