Smart meters are Internet of Things (IoT) devices that measure and transmit data about electricity, water, and gas consumption. Using connected sensors, they share information directly from utility meters, so providers don''t need to manually check installations to charge customers and manage infrastructure. Through smart …

8.1 Introduction. Metering and sub-metering of energy and resource use is a critical component of a comprehensive O&M program. Metering for O&M and energy/resource eficiency refers to the measurement of quantities of energy delivered, for example, kilowatt-hours of electricity, cubic feet of natural gas, pounds of steam, and gallons of water.

In smart metering, there are two groups of communication technologies: Wired and Wireless . The wired communication uses data transmission over a wire-based technology. The main idea is to use transmission lines (e.g., telephone lines, fiber optic, coaxial cable, etc.) and power lines as the communication medium.

The metering device, located between the condenser and evaporator, converts the high-pressure, high-temperature refrigerant from the condenser into a low-pressure, low-temperature mixture of liquid and vapor refrigerant. In direct expansion (DX) evaporators, the refrigerant mixture entering the evaporator is about 75% to 80% liquid refrigerant ...

The metering device is a restriction to refrigerant flow. This maintains a pressure difference between the relatively lower pressure evaporator and the relatively higher pressure liquid line. As the refrigerant is exposed to the lower pressure in the evaporator, it expands and becomes a vapor at the low side saturation temperature, also …

6 min read. Net metering is an electric billing tool that uses the electric grid to "store" excess energy produced by your solar panel system. Under net metering, the energy produced by your solar panels that you don''t use is credited back to you. On a cloudy or rainy day when your panels aren''t producing enough energy, the utility grid will ...
