<p>The present invention relates to a volume perceiving liquid flow meter program and a liquid flow rate measuring method. More specifically, the present invention provides the liquid flow rate measuring method comprising the steps of inputting a type, temperature (T), pressure (P), and a pressure difference (dP) of liquid to be measured, an inlet diameter (D) of a fastener flow measuring device, and a diameter (d) of a throat; selecting an input constant depending on the type, the temperature, and the pressure of the liquid from a database of the input constant (viscosity of the liquidμ, the densityρvalue of the liquid) depending on the predetermined liquid; correcting an outflow coefficient (C); and substituting a computed expansion coefficient, the corrected outflow coefficient and a pressure difference, a throat diameter, a diameter ratio, and the density of the liquid for a liquid flow rate measuring formula.</p> |
