Prepaid flowmeter for heating network, steam valve control system, intelligent heating design

Description :

　　Qingdao Zhiyuan Instrument Prepaid Calculator complies with the JJG1003-2016 standard and meets the trade settlement requirements of the new metering regulations for integrated calculators.

　　A. Instrument model EF-II/TCP, LCD display screen.

　　B. The instrument has an accuracy of ± 0.2% and is capable of outputting 4-20mA analog signal current (output category can be freely defined).

　　C. The function of intelligent accumulation instrument is to measure pressure, temperature, instantaneous flow rate, cumulative flow rate, frequency, differential pressure, steam balance, power outage frequency, power outage and incoming call time, daily cumulative monthly cumulative query, etc. It is programmable and can set parameters according to actual needs;

　　D. Multiple cumulative methods (lower limit flow, over flow), cumulative coefficient (percentage) can be set. It can be set that when the flow rate is less than a certain percentage of the range (such as 10%), the lower limit flow rate will be accumulated according to this fixed value. It can also be set that when the flow rate is greater than a certain percentage of the range (such as 110%), the excess flow rate will be accumulated according to the set multiplier, thus solving the problem of low flow rate in small flow and excess flow measurement and meeting the actual needs of heat network calculation.

　　Heating metering is still more inclined towards smart heating, which is a direction and a development trend. Now heating metering has stepped on a key point in the development of the heating industry towards smart heating. It has virtually promoted the development of the industry. It has played a role in promoting the development of the heating industry through cloud computing measures such as big data, the Internet of Things, and the Internet.Prepaid flowmeter for heating networkThe continuous acceleration of urbanization has led to a growing user base for projects that benefit people's livelihoods, such as water, electricity, and gas. At the same time, how to charge for these projects has become an urgent problem to be solved. After the emergence of intelligent meter reading systems, the problem of hot water and steam billing has been solved. Currently, there are many technologies used for meter reading in China, such as manual meter reading, RS485 bus, infrared and wireless data remote transmission, among which GPRS wireless data remote transmission and RS485 bus meter reading technologies are relatively mature and widely used. The data transmission of high-level networks adopts fiber optic transmission with good compatibility, high reliability, fast data transmission speed, and long transmission distance

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid flowmeter for heating networkIntelligent report 1. It can automatically generate daily reports, monthly reports, annual reports, and reports, and can print reports in real time. 2. It can query historical data reports for any hot user, any parameter, and any time period, and supports exporting statistical reports and analysis curves. 3. It can print daily, monthly, and detailed reports on gas consumption for each individual user and all users, as well as contemporaneous and annual reports, and can be archived as Excel files (*. xls). 4. The report format can be created according to the requirements of the bidding party, and the system needs to have monthly automatic settlement function to generate electricity meters. 5. IC card prepaid recharge lightning protection function: The box machine is equipped with lightning protection modules, but the control box must be reliably grounded. The wired data acquisition system is based on the RS485 bus. The RS485 wired data remote meter reading system is a system that uses modern communication and computer network technology to automatically read remote data

　　Application of Qingdao STR/WEB/V2.0 Qingdao Zhiyuan Instrument Intelligent Heating System: Prepaid flowmeter for heating networkThe main application is to achieve intelligence and ensure thermal balance of heat source output. Install temperature, pressure, flow and other sensors at each heat source unit and pipeline outlet to calculate the energy consumption of each link, display information on inlet and outlet temperature, pressure, flow and other aspects. The sensors will send the collected information to the heating dispatch center to achieve real-time monitoring of various parameter information.Prepaid flowmeter for heating network, steam valve control system, intelligent heating designIn the application of heat source, it is also necessary to monitor load and weather changes, combine specific weather and load conditions, adhere to the principle of economic operation, compare the required heat with the heating amount, draw the trend curve of changes, and judge whether to start or stop the furnace. This will meet the heat needs of users without energy waste and save heating costs.
