Five Features of Smart Meters

Compared with the first smart meters, smart meters not only increase efficiency but also cut costs. At present, it is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. The reason why it is used and favored by the energy industry is that it is inseparable from its own characteristics and advantages. 1. The high-accuracy smart transmitter has high accuracy: The built-in microprocessor can measure static pressure and temperature changes in real time. The influence of the detection element is corrected by the data processing, and the hysteresis and reproducibility are compensated to make the output signal more accurate. In general, the accuracy is ±0.1% of the maximum range, and the digital signal can reach ±0.075%

2. Strong function: The intelligent transmitter has a variety of complex computing functions, relying on the internal microprocessor and memory, can perform square, temperature and pressure compensation and a variety of complex operations.

3, the measurement range is wide: the maximum range ratio of the ordinary transmitter is 10:1, and the intelligent transmitter can reach 40:1 or 100:1, the migration amount can reach 1900% and -200%, reducing the transmitter Specifications, enhanced versatility and interchangeability, bring a lot of convenience to users.

4. Strong communication function: The smart transmitter can realize the operation of the communicator. The communicator can be inserted into the corresponding jack of the transmitter at the site, or the communicator can be connected to the transmitter in the control room. On the signal line of the instrument, zero point and span adjustments and changes are made. Some transmitters have both analog and digital output methods (such as the HART protocol), laying the foundation for fieldbus communication.

5. Perfect self-diagnosis function: Through the communicator, you can find out the failure result information of the transmitter self-diagnosis.

With automatic communication functions such as infrared rays of smart meters, automatic meter reading can be realized. This not only improves efficiency, but also cuts the cost of meter reading. In addition, it can also reduce the mistakes caused by human factors, but also make gains.
