摘要： 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.

摘要： 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.

摘要： 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.
