    摘要: A phase angle difference between two alternating electrical signals is determined as a function of a ratio of a differential combination of two different numbers of pulse counts to an additive combination of the two different numbers of pulse counts, wherein the first of the two different numbers of pulse counts is obtained by counting a series of electric pulses generated by an electrical pulse generator in a time interval between an occurrence of zero value of the leading signal of the two alternating electrical signal and (i-1)th occurrence of zero value of the trailing signal of the two alternating electrical signals occurring after the occurrence of zero value of the leading signal, and the second of the two different numbers of pulse counts is obtained by counting the pulses in an time interval between an occurrence of zero value of the trailing signal and the (j)th occurrence of zero value of the leading signal occurring after the occurrence of zero value of the trailing signal, wherein (i) and (j) are integers; and the phase angle so determined is used to determine the mass flow rate of media by using a convective inertia force flowmeter.
