Distributed measurement system for heat metering and control

Measuring and charging heat consumption are not often worked out in the prevalent warm-water heating systems. The developed modern heat-meter device, which includes a microcontroller, is self-calibrating and self-testing; it uses several correctional algorithms in order to increase accuracy after authentication. Consumption data and information about the work-state events are logged and stored by the measuring unit. The discrete devices are connected to a local concentrator via M-bus. The concentrator is connected to the central supervisory system through a mobile communication channel. In this system, the meter devices respond to arising failures. The center collects information about measuring and usage. This solution highly increases the efficiency and the reliability of the system.
