Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water consumption, transmit water consumption data, and settle transactions. Compared with traditional water meters, which generally only have the functions of flow collection and mechanical pointer display of water consumption, it is a great progress. In addition to recording and displaying water usage electronically, smart water meters can also control water usage according to agreements.
With the development of modern science and technology, the power grid has also moved towards intelligence. Smart meters are the terminal of smart grids. Compared with traditional mechanical meters, they have significant differences. They integrate multiple technologies, have a higher degree of scientificity, and have multiple characteristics of automation, informatization, and intelligence. Moreover, they have powerful and diverse functions, greatly simplifying related work, improving the efficiency and stability of power grid operation, and optimizing power grid services.
A heat meter is an instrument for calculating heat. The working principle of a heat meter is as follows: a pair of temperature sensors are installed on the upstream and downstream pipes passing through the heat transfer fluid, and a flow meter is installed on the fluid inlet or return pipe (the measurement results vary depending on the installation position of the flow meter). The flow meter emits a pulse signal proportional to the flow rate, and a pair of temperature sensors provide analog signals indicating the temperature. The calculator collects signals from the flow and temperature sensors and uses calculation formulas to calculate the heat obtained by the heat exchange system.
At present, there are several types of smart gas meters in China, including IC card smart gas meters, CPU card smart gas meters, RF card smart gas meters, direct reading remote transmission gas meters (wired remote transmission meters), and wireless remote transmission gas meters (integrated). With the improvement of people’s living standards and quality of life, the demand for intelligent products in modern households will promote the development of smart gas meters towards safety, reliability, and intelligent convenience.
The company independently develops lithium batteries with the characteristics of long-term microcurrent operation, stable working voltage, high safety, and wide temperature range (-40 ℃~+85 ℃). Ensuring the safety, stability, and accuracy of intelligent instruments and meters during use.
