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.
