Title
(EN) Ultrasonic transducer, flow meter and method
(ZH) 超声传感器、流量计和方法
Abstract
(EN) An ultrasonic transducer for a pipe includes an ultrasonic source which produces plane waves. The transducer includes a housing having a face at least a portion of which is curved through which the plane waves produced from the source disposed in the housing are emitted and directed outward towards the pipes interior wall so a full cross-section of the pipes interior can be measured. A flow meter for detecting fluid flow rates in a pipe. A method for detecting fluid flow rates in a pipe.
