A computer implemented method implemented on a computer system includes non-transient memory storing instructions for configuring a plurality of district metering areas within a utility supply network. The method includes identifying a plurality of flow measurement devices, wherein each flow measurement device is connected by a directional connection to at least one other flow measurement device, generating a utility supply network representation based on the directional connections between the flow measurement devices, and generating a plurality of district metering areas for the utility supply network representation, each district metering area being a directed acyclic graph based on the directional connections and including a subset of the plurality of flow measuring devices and including at least one flow measurement device designated as a supply meter and at least one flow measurement device designated as a demand meter.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. Internet-of-Things (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes (pool logic) which can be embodied as software code installed in any of the various embodiments of the present disclosure.

An arrangement for installation in a fluid line network contains a fluid meter having a housing with a fluid inlet and a fluid outlet, and a volume measuring part. At least one connector, which is intended for connection to the housing of the fluid meter, is either equipped with an additional function or configured for the adaptation of an additional function on the connector. The connector has a connector inflow and a connector outflow. The fluid meter and the connector form a modular unit that can be installed in the fluid line network.

Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor.

A flow meter ultrasonically measures fluid velocity in a pipe and ultrasonically transmits fluid flow data along the pipe. An ultrasonic transducer used for fluid velocity measurement may optionally also be used for communication of flow data, and optionally, the ultrasonic frequency for fluid velocity measurement may be the same as the ultrasonic frequency for communication of flow data.

A liquid product distribution network includes a liquid product distribution monitoring and reporting apparatus for operation in association with a tap handle flow monitoring and reporting apparatus. The liquid product distribution monitoring and reporting apparatus includes a radio transmitter device and sensing circuitry for sensing and communicating physical properties associating with the keg. A tap handle flow monitoring and reporting apparatus senses flow of a liquid through a tap includes a tap handle radio transmitter device for fitting within and protected by a tap handle and a low-energy consumption tap handle radio/processing module. A mobile communications device with geographic position sensing device and/or said tap handle flow monitoring and reporting apparatus passively and without user interaction within the liquid product distribution network, without using network uplink/gateway circuit devices for sensing and reporting fluid storage, flow, and financial operations relating to the distribution of said liquid product throughout the liquid product distribution network.
