Four departments including the National Development and Reform Commission and the National Energy Administration have formulated the "Regulations for the Fair Opening of Oil and Gas Pipeline Network Facilities", which re-emphasizes the opening of pipeline network facilities, and emphasizes the use of natural gas calorific value measurement by pipeline network operators, and gives Date requirements, Article 13 of the original text: When natural gas pipeline network facility operators receive and deliver natural gas to users on behalf of natural gas production and sales companies, they shall scientifically measure the calorific value, volume, and quality, and accept the government's administrative department for measurement. Metrological supervision and inspection. The State promotes natural gas energy measurement and pricing, and establishes a natural gas energy measurement and pricing system within 24 months from the date of implementation of these Measures.

　　According to market demand, Prehot Energy Services has united with many domestic and foreign intelligent flowmeter manufacturers to implement intelligent energy management system construction for national long-distance natural gas pipeline networks and provincial natural gas pipeline networks. The intelligent method of "analysis" replaces the traditional method of "a large number of personnel on-site investigation and non-professional analysis", which greatly improves the accuracy and reliability of the metering system, and implements equipment management, transmission difference analysis and control of energy metering in time, and can be effective Save the cost of measuring professionals to and from the site, improve the efficiency of maintenance and repair.
