Abstract

PURPOSE: To obtain the apparatus of the simple entire constitution by using ultrasonic beams in detecting the fluctuation components included in the fluid to be measured and using the piezoelectric elements provided with plural electrodes as receivers of the beams.
CONSTITUTION: An ultrasonic wave transmitter 2 and a receiver 3 are opposedly disposed in a pipeline 1 in which the fluid to be measured flows, in such a manner that beams cross the flow. The receiver 2 comprises mounting a sheet of electrode 21 to a sheet of flat plate form piezoelectric element 20, from which band form ultrasonic beams are radiated. The receiver 3 comprises mounting electrodes 31, 32, 33... of a width d at an equal spacing L to a flat plate form piezoelectric element 20 and respectively alternately connecting the electrodes one after another. Output of an oscillating circuit 5 is connected to the transmitter 2. The signals from the odd number receivers and the signals from the even number receivers are inputted respectively to a phase difference demodulating circuit 6, by which the phase differences of both signals are demodulated. This enables the spacing L and width d of each electrode to be provided accurately and enables the constitution as the entire part to be simplified.
