Abstract: Embodiments of systems and methods are provided to monitor operation of a compound water meter comprising a low flow meter and a high flow meter. In the disclosed embodiments, a first sensor package is coupled to the low flow meter to generate a first set of sensor data for monitoring operation of the low flow meter, and a second sensor package is coupled to the high flow meter to generate a second set of sensor data for monitoring operation of the high flow meter. The first and second sensor packages may each include, e.g., an optical sensor, a magnetic sensor and a vibration sensor. In the disclosed embodiments, the first and second sets of sensor data are analyzed to detect various potential problems within the compound water meter, such as a register failure, a crossover failure, a measurement failure, a bypass open condition and/or an incorrect flow meter size.

Abstract: An infrastructure and methods for the analysis of flow in pipe systems. In a preferred form, the infrastructure and methods account for energy status of a sensor device and wear cost functions. The infrastructure comprises a controller and a plurality of sensor devices coupled to the pipe system to collect measurements related to one or more of the following: vibration, magnetic field, fluid pressure, temperature, humidity, chemical composition of the fluid, fluid flow or fluid throughput. The controller has access to a database containing one or both of—(i) current energy status of a sensor device and/or (ii) a cost allocation relating to use of a sensor device and assigns workloads using energy status and/or cost.

Abstract: A retrofit device and method of installing such a device for supplementing a legacy flow meter in a fluid pipe system. The retrofit device enhances the function of the legacy flow meter by providing a digital interface and means for error diagnostics and tamper detection. The retrofit device adapts to the mechanical and casing form factor design of the legacy flow meter, particularly a flow meter already installed, such as buried in the ground.
