Abstract: Systems and methods for performing external ultrasonic flow metering are illustrated. One embodiment includes an ultrasonic flow meter with a clamp-on carrier assembly, wherein the clamp-on carrier assembly includes a ratcheting clamp configured to externally mount the clamp-on carrier assembly to an assessed pipe. A medium has a direction of flow through the assessed pipe. The ultrasonic flow meter further includes at least three ultrasonic transducers, mounted to the clamp-on carrier assembly. Each of the at least three ultrasonic transducers is configured to transmit and/or sense ultrasonic acoustic waves propagating through the medium in the assessed pipe. The ultrasonic flow meter further includes a processor, mounted to the clamp-on carrier assembly and configured to calculate a flow rate for the medium based on time of flight measurements determined between two or more of the at least three ultrasonic transducers.

Abstract: Embodiments include a novel, easy to install, non-intrusive, ultrasonic water flow meter with a self-calibrating three-piezoelectric transducer configuration attached externally to a water pipe, that allows for accurate measurement of water flow, and can provide the flow data to a remote system for billing and further analysis. The water flow data can further be analyzed for water consumption by individual fixtures, in support of conservation and usage management efforts.
