Abstract
An ultrasonic flowmeter includes a meter body including a flow passage having wetted surfaces through which fluid flow is to be measured. The flowmeter includes a non-stick coating adhered to the wetted surfaces of the meter body. The flowmeter includes a first transducer and at least a second transducer arranged around the flow passage to transmit and receive ultrasonic energy. The flowmeter includes an electronic unit designed to generate and receive electronic signals from the transducers and to process the signals in order to compute information related to the fluid flow rate through the passage. A method for measuring fluid flow with an ultrasonic flowmeter. A method of making an ultrasonic flowmeter.
