METER OF FLUID MEDIUM QUANTITY AND METHOD TO DETERMINE QUANTITY OF FLUID MEDIUM Russian patent published in 2015 - IPC G01F1/00 

FIELD: measurement equipment.

SUBSTANCE: meter comprises a controller, a tachometric converter connected to a controller, which records and counts pulses of the tachometric converter and also determines quantity of fluid medium that leaked through the meter. At the same time it also comprises a clock pulse oscillator connected to the controller, at the same time the controller is made as capable of determining the number of pulses of the clock pulse generator N_t between serial pulses of the tachometric converter, determination of the weight coefficient W(N_t), corresponding to current value of quantity of pulses of the clock pulse oscillator N_t, and correction of the number of pulses of the tachometric converter by a weight coefficient W(N_t). The proposed method to determine quantity of the fluid medium is carried out by means of the meter.

EFFECT: increased accuracy of measurement of leaked quantity of fluid medium, reduced number of counting operations from the moment of readings taking to the moment of measurement results display, which reduced the rated error at each stage and decreases rated errors in general.
