Abstract
The present invention is directed to a flowmeter comprising a piezoelectric sensor. The flowmeter is configured so that fluid flow through a channel, typically either a fluid conduit or a housing in which the sensor is oriented, produces oscillating stresses in a piezoelectric material. The oscillating stresses produce an electric signal. Characteristics of the electric signal, such as the magnitude of the signal at particular frequencies, can be measured and used to determine the rate of fluid flow through the channel.
