The Northbrook, Ill.-based capital goods manufacturer produces pumps, metering devices and other industrial equipment.
The common communication service interface can be used to provide unified service for different devices, i.e., metering devices, measuring device, and the controlling devices, etc. Open image in new window Fig. 3 Common communication service interface design for further electric service access.
Smart grid applications such as automatic meter reading, remote system monitoring, and equipment fault diagnostics require reliable two-way WSN communications between electric utilities and the customerŠs metering devices [1].
The main pieces of equipment are a suction unit, some flow metering devices, an electrocardiograph, a pulsioximeter, two defibrillators (a portable one and a fixed one), two infusion pumps (volumetric and syringe type), three respirators and a mobile incubator.
However, variations in measurements between metering devices complicate the process of compiling the necessary appliance profiles.
This explains the high power consumption of the metering devices and makes it less suitable for metering low-energy consumers.
Another system is designed to make integration and interconnections of new metering devices and visualizations simple and constitutes a good basis for further research on awareness of energy usage in our (future) living environments [9].
Advanced metering infrastructure (AMI) is the technology of automatically collecting data from energy metering devices and transferring that data to a central database by communication technology for remote control and analyzing.
It has also been selected by a large number of utilities as the communications platform of choice for their smart metering devices as it provides a standardized platform for exchanging data between utilities and smart metering devices and appliances located on customer premises [10].
The receiver-drier is used when a thermostatic expansion valve metering device is used and is positioned between the condenser and the thermostatic expansion valve.
