DEVICE MEASURING PARAMETERS OF LIQUID FUEL Russian patent published in 2001 - IPC

FIELD: measurement technology. SUBSTANCE: device measuring parameters of liquid fuel has controlled generator, information processing unit, unit controlling frequency of controlled generator, indicator, unit measuring actual part ε′ of complex dielectric constant which incorporates reference frequency generator, mixer and frequency meter, measurement and standard resonators connected to output of frequency-controlled generator and coupled with outputs to proper inputs of detector of unit measuring imaginary part ε″ of complex dielectric component and output of detector is connected through analog-to-digital converter of same unit to input ε″ of information processing unit. Output of reference frequency generator is connected to one of inputs of mixer whose second input is linked to output of frequency-controlled generator and whose output is connected to input of frequency meter connected with output to input ε′ of information processing unit. One of outputs of the latter is connected through control unit to controlling input of frequency-controlled generator, second output of information processing unit is linked to indicator and its third output is used for connection to outside computer. EFFECT: provision for timely measurement of octane and cetane numbers of liquid fuel with high accuracy and authenticity of results, for automation of test and control over modes of technological cycle. 1 dwg
