What happen if the flow have bubbles ?

[@CeramTecCeramicExperts]

Sound will travel differently through air than through water and since the transducers are designed to work with water, when bubbles will appear in water between transducers or on the surface of the reflectors or on the face of the transducers the signal amplitude will drop. For flow measurement, while using 2 or more transducers ‘talking to each other’, Time of Flight might change while sound wave will meet bubbles in the flow. The change will depend on size and amount of bubbles.

will there be 2 pulse output wire this kind of flow sensor? one is for transmit and one for receive?

[@CeramTecCeramicExperts]

Each transducer will have two wires: one connected to negative and one to positive electrode of the PZT element. Each transducer can work as transmitter and receiver.
