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

According to at least one aspect, a monolithic sensor mount can include a first cylindrical portion and a second cylindrical portion. The first cylindrical portion can have a first diameter and the second cylindrical portion can have a second diameter larger than the first diameter. The second cylindrical portion defining a recess region to host an ultrasonic transducer. The second cylindrical portion can have an outer surface that defines a male thread to mechanically engage a female thread of a cavity within a fluid flow tube configured to host the sensor mount.

Sensor mount

Fluid flow tube

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

An ultrasonic fluid flow meter can include a casing structure including a hook portion configured to engage a conduit to secure the casing structure to the conduit. The ultrasonic fluid flow meter can include a transducer block disposed within the casing structure and seating ultrasonic transducers. A distance between the hook portion and the transducer block along a direction transverse to the transducer block can be adjustable. The ultrasonic transducers can face the conduit when the casing structure is secured to the conduit via the hook portion.

Ultrasonic sensor assembly for fluid flow meters

Fluid flow meter

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.
