Abstract: The information of Jingda remote centralized reading control system is provided by excellent flowmeter and flowmeter production and quotation manufacturers. 1. System description Hangzhou Jingda remote meter reading system is independently developed by the company. It integrates intelligent meter, computer and network communication technology. It has the functions of real-time and fixed-point information copying, storage, query, statistics and meter control. of. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. 1. System description Hangzhou Jingda remote meter reading system is independently developed by the company. It integrates intelligent meter, computer and network communication technology. It has the functions of real-time and fixed-point information copying, storage, query, statistics and meter control. collection management system. The biggest feature of the system is easy implementation and reliable operation. According to the statistics of the operation of 130,000 remote meters installed by PetroChina in the past three years, the success rate and accuracy of meter reading are both over 99%. It is a set that can be widely used. Meter reading system. Through analysis of the collected data, a digital energy management system can be established to analyze the energy consumption of a certain region or the entire city, and provide a basis for decision-making for energy conservation and emission reduction. 2. System composition The bus-type remote centralized reading control system consists of the following parts: data centralized reading management center (including centralized reading management software, server equipment hardware); data concentrator; electronic direct reading meter. 3. The data transmission mode is adopted in the centralized copy system“Centralized data center - data concentrator - meter”Three-level architecture, two-level transmission mode. The first-level transmission is a fixed communication method between the meter and the concentrator. The meter supports the M-BUS interface and follows the DL/T645 or CJ/T188 protocol; the second-level network is the communication between the concentrator and the centralized data center. According to the actual situation of the user, the existing resources can be fully utilized, and the Ethernet or GPRS access network can be flexibly adopted. [Note]: M-BUS technical description M-Bus is a bus structure specially used for public utility meters, called Meter-Bus, or M-Bus for short. Its working principle is to use modulation and demodulation technology for data transmission on DC low-voltage power lines. The M-BUS special chip is embedded in the instrument and the concentrator, and the data transmission is carried out by using a specially designed two-core wire. It has the following technical characteristics: high-speed and stable communication rate, reliable communication over long distances; wiring methods of arbitrary wiring branches such as string, star, and cross are allowed; ordinary parallel or twisted pair wires are used, and non-polar two-wire installation wiring; isolation Communication equipment, constant current current loop communication mode, strong anti-interference; with functions such as automatic device registration, can accommodate a variety of devices, reserve a variety of communication protocols, easy to expand; can supply power to slave meters through the bus, very low of static power consumption. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Jingda Remote Collective Copying Control System'

have manifold mass flow meter effects, ranging from endress hauser ultrasonic flow meter to rosemount coriolis mass flow meter.

Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as mass flow meter of our business mission.

Overall, mass flow meter may be a great way for manufacturers to expand their use of technology, but the price could present a significant hurdle for some businesses.

Beijing Sincerity Automatic Equipment Co., Ltd's core technology of mass flow meter enables us to understand and utilize in a right way.

Obviously, financial return is important in manufacturing mass flow meter, but I think that's not enough. I think many customers want to support something they really believe in.
