A fluid flow meter system for monitoring fluid flow through a lumen includes a first ultrasonic transducer configured to transmit one or more versions of a transmit (TX) signal through a fluid flowing within the lumen, and a second ultrasonic transducer configured to receive one or more respective receive (RX) signals. The fluid flow meter system includes an analog-to-digital converter (ADC) configured to sample, at a first frequency, the one or more RX ultrasonic signals and a processor configured to generate a fine resolution signal based on the one or more RX ultrasonic signals. The fine resolution signal is associated with a second sampling rate higher than the first sampling rate. The processor is also configured to compute a cross-correlation signal indicative of cross-correlation between the fine resolution signal and a waveform and determine an estimated fluid flow parameter based on the computed cross-correlation signal.

Method and system for fluid flow rate measurement

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.

Flow meter configuration and calibration

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.

System, apparatus and method for automatic pipe type detection

A fluid manifold is capable of channeling and monitoring fluid flow within a fluid distribution system. The manifold includes one or more input lumens. Each input lumen associated with a respective inlet port. The manifold also includes a plurality of output lumens such that each output lumen is associated with a respective outlet port and at least one input lumen is coupled to two or more output lumens. The manifold also includes one or more flow sensors capable of measuring fluid flow parameters of fluid flowing through at least one of the one or more input lumens and the plurality of output lumens. In some implementations, a flow sensor can be mounted to each output lumen of the manifold.

Devices and system for channeling and automatic monitoring of fluid flow in fluid distribution systems

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.

Methods and apparatus for fluid flow monitoring and leak detection

Systems and methods described herein allow for reliable and computationally efficient detection of fluid leak events or abnormal fluid usage/flow events. A fluid flow meter can measure fluid flow parameter values during a training phase. The fluid flow meter can generate, using the fluid flow parameter data, a training fluid flow duration pattern indicative of, for each value range of a plurality of value ranges of a respective time threshold value. The time threshold value can represent an estimate of a maximum fluid flow duration, within a given fluid flow event, for fluid flow associated with the corresponding value range. During a detection phase, the fluid flow meter can determine, for a value range, a respective fluid flow duration within a current fluid flow event. The fluid flow meter can detect a leak event upon the fluid flow duration exceeds the time threshold value for the same value range.
