PROCEDURE DETERMINING CONTROL VOLUME OF GAUGING TANK IN TESTING INSTALLATIONS FOR WATER AND FLOWMETERS Russian patent published in 2000 - IPC

FIELD: measurement technology. SUBSTANCE: volume of water continuously fed into gauging tank with specified flow rate is converted with the aid of water meter fitted with pulser to proportional number of electric pulses. Number n of these pulses is counted during period between moments when level of water in gauging tank runs into lower and upper test marks as well as total number N of pulses during period between start and stop of water feeding into gauging tank. Total volume V of water fed into gauging tank between start of stop of its feeding is measured with the help of water measuring tube. Control volume of gauging tank is found by dependence V_k=n/N V. EFFECT: increased precision of measurement of control volume of gauging tank due to account of volume of jet of water fed into it. 1 dwg
