The proposed system allows the measurement of three parameters: the amount of flooded oil Q, the amount of clean oil Q ( ) H is the quantity Q0Q QW / (; Io (.t), whereUU is the humidity of the oil in relative units, t is the oil temperature in C, and ob is the modulus of the temperature coefficient of the dielectric constant of oil. The device operates as follows. yes 5 (e.g., turbine type) through the shaper 6 and the friction compensator 7, the frequency-pulse signal q proportional to the volume flow of the water-in-oil flow is fed to the input of the scaling binary counter 8, with the scaling factor Cdc, and then into the accumulator 9.

To determine the amount of pure oil Q c, a signal is formed in the device (a digital code) proportional to the humidity temperature corrected eft; W W / (1-оС t) The process of forming the signal W proceeds as follows. The humidity converter 10 generates a frequency signal supplied to one of the outputs of the matching circuit 11, to the second input of the matching circuit of the multivibrator 12, triggered by the overflow pulses of the counter 16 of the binary multiplier 13, is fed to the pulse to the duration. As a result, a unitary code y is formed at one of the inputs of the functional converter, proportional to the oil's moisture content W, and at the second input, an NQ code proportional to the value of ot t g from the multiplication unit 14. The functional converter generates a code. proportional to the humidity of the oil corrected for temperature (i-oCt), which is written to the register 2 of the binary multiplier 13.

The binary multiplier analyzes the operation of multiplying the position code for humidity N yy by the frequency-pulse signal i Q of the volume flow of oil and subtracting the resulting product from f o. Binary output
