FIELD: instrumentation.

SUBSTANCE: proposed method consists in breaking down power output in operation at load and idling into intervals defined experimentally. Then, fuel output at each interval of power output is calculated by appropriate formula. Obtained fuel consumption is compared to actual magnitude. This allows comparing actual consumption with design consumption without breakdown into power output and idling. Design total fuel consumption results from adding design fuel consumption and that in idling at preset time interval.

SUBSTANCE: proposed method comprises filling the tank with fluid and semi-fluid mixes, setting volumetric portion of mixes and draining said tank in dispensing said mixes. Mix level capacitive transducer is arranged inside tank along its height to be filled with mixes at a time with said tank. Structural characteristics of transducer and electrical performances depending thereon are invariable over its height in empty state of both transducer and tank. Maximum and minimum tank mix levels are set by appropriate transducers. Tank filling is terminated when mix level reaches that of mix top level transducer and started when it reaches that of mix bottom level transducer. Electric oscillation signal is generated at capacitive transducer. Electric oscillation signal amplitude is measured at capacitive transducer. Mix level signal is generated subject to measured electric oscillation signal amplitude at capacitive transducer. With top level transducer level reached by mix level, product of height from tolerable top to bottom mix levels and said electric oscillation amplitude is determined for said time interval. Mix level signal is corrected in relation to measured electric oscillation signal amplitude at capacitative transducer. With tank drained at beginning of another proportioning cycle, initial mix level generated signal is determined. Final proportioning mix level signal is defined as difference between mix level initial signal and quotient of mix volumetric portion and tank horizontal section inner area. Definite final level signal is compared with corrected mix level signal to terminate volumetric proportioning of mixes if said signals are equal. Proposed device comprises tank, mix level capacitative transducer, mix top and bottom level transducers, electric oscillation generator, signal transducer, pump and shutter control unit, pump and shutter assemblies and mix measured level indicator. Output of said generator is connected with capacitative transducer and signal transducer input.
