Abstract: Methods and systems for configuring a fluid flow meter include a processor obtaining a measurement signal recorded by the fluid flow meter. The processor can determine a whitening frequency band. The processor can then construct a whitening filter based on the measurement signal and the whitening frequency band. The processor can then generate a reference signal based on the whitening filter and the measurement signal. The processor can provide the whitening filter and the reference signal for use by the fluid flow meter to measure a time shift between the reference signal and another measurement signal.

Abstract: A fluid flow meter can include a sensor capable of transmitting a transmit signal to propagate, at least partially, through a fluid in a pipe and receiving a respective receive signal. The fluid flow meter can include a memory storing computer code instructions and a plurality of pipe type signatures associated with a plurality of pipe types. Each pipe type signature of a respective pipe type of the plurality of pipe types can include one or more characteristics of receive signals associated with that pipe type. The fluid flow meter can also include a processor communicatively coupled to the sensor and to the memory. When executing the computer code instructions, the processor can determine one or more signal features of the receive signal, and identify a pipe type of the pipe based on the one or more signal features of the receive signal and the plurality of pipe type signatures.

Abstract: According to at least one aspect, a fluid flow monitoring system includes an ultrasonic sensor for generating measurement signals associated with respective ultrasonic signals propagating through the fluid in the lumen, a shut-off valve for blocking fluid flow in the lumen, and a controller. The controller can be communicatively coupled to the ultrasonic sensor and to the shut-off valve. The controller can be configured to compute a plurality of fluid flow parameter estimates based on a plurality of measurement signals generated by the ultrasonic sensor over a time window while the shut-off valve is open. The controller can obtain an offset value associated with fluid flow parameter measurements during a zero flow state of the shut-off valve. The controller can then check for presence of a fluid leak event based on the fluid flow parameter estimates over the time window and the offset value.

Abstract: A sensor assembly is configured to mount transducers on a conduit, such as a pipe, for measuring properties of a fluid flowing in the conduit. The sensor assembly can include a sensor cradle capable of seating and maintaining a pair of transducers. The sensor assembly can include a mounting device arranged to couple the sensor cradle to the conduit such that the transducers maintained at the sensor cradle are oriented to allow transmission of ultrasonic waves traversing the conduit. The sensor assembly allows for mechanically stable coupling of the transducers to the conduit. The transducers can be fixed to the sensor cradle though an adhesive. In some implementations, the transducers can be oriented substantially orthogonal to each other.
