How Wireless Remote Monitoring Enables Low-Cost Data Logging and Control
Economically meeting requirements for monitoring of mobile assets and remote processes always presents project engineers a considerable challenge. While the initial requirements are reasonable, complexityinvariably emerges when the needs of all interested parties are assessed.
This is particularly the case when the asset or process consists of a small number of monitoring points. The requirements can be regulatory or economically-driven. For example, monitoring of combined sewage overflow (CSO) by water utilities meets a regulatory requirement. Compliance with mandates from agencies such as the EPA calls for monitoring of remote locations in which only a single measurement, flow or level, is taken per site.
Monitoring of vendor-managed inventory, such as a chemical level in a tank, is an economically-driven example. Again, only a single measurement, tank level or pressure, is required. Economic goals include customer satisfaction and operation of the delivery/service fleet in the most efficient manner.
Leased generators and pumps exemplify mobile assets in which, at minimum, one or two measurements are recorded. In those cases, however, requirements could grow to dozens of measurements. Customer satisfaction and optimal management and maintenance of the asset inventory are the goals.
