Abstract
A wireless surface wave flow sensor can be utilized for monitoring the flow of fluid. Such a surface wave flow sensor can be configured to include one or more interdigital transducers and a self-heating heater formed upon a piezoelectric substrate. The interdigital transducer(s) can be selected to convert electrical signals to surface waves thereof. An antenna can also be connected to the surface wave device, wherein the antenna can receive one or more signals, which excites the acoustic device to produce a frequency output associated with the flow of the fluid for analysis thereof.
