As a flow measurement device, electromagnetic flowmeter plays a crucial role in the entire smart heating system. Electromagnetic flowmeter is generally installed on the supply/return water pipes of the heating secondary pipeline network. By measuring the supply and return water flow rate of the pipeline network and the temperature difference of the supply and return water pipe network, the heat expenditure of the pipeline network heating is obtained according to the energy conversion formula Q=Cm △ t, thereby obtaining the basis for adjusting the valve opening.

In the field of municipal water supply, pipeline leakage is a major challenge faced by various water companies. Traditional leakage monitoring methods such as listening method and radar method cannot meet the real-time leakage monitoring of large-scale pipelines due to their long time consumption and high labor costs. With the development of technology and DMA partition metering technology, nighttime small flow analysis has become an important means of leak monitoring.

The Roots flowmeter integrates temperature and pressure acquisition functions, which can directly obtain the volume flow rate under standard conditions through the calculation of the volume correction instrument, facilitating settlement. Flow, temperature, pressure and other data can be uploaded to the billing settlement system through the built-in infinite remote transmission module of the Roots flowmeter using various methods such as 4G, NB-IOT, LORA, etc. At the same time, the valve control system matched with the Roots flowmeter can open and close valves based on information such as gas consumption and prepaid amount, achieving the goal of intelligent charging.

The gas turbine flowmeter integrates temperature and pressure acquisition functions, which can directly obtain the volume flow rate under standard conditions through the calculation of the volume correction instrument, facilitating settlement. Flow, temperature, pressure and other data can be uploaded to the billing settlement system through the gas turbine flowmeter's built-in infinite remote transmission module using various methods such as 4G, NB-IOT, LORA, etc. The valve control system, which is also compatible with the gas turbine flowmeter, can open and close valves based on information such as gas consumption and prepaid amount, achieving the goal of intelligent charging.

The vortex flowmeter, as an excellent velocity flow instrument, is particularly suitable for measuring media such as compressed air. It can accurately measure the air output and pressure of the air compressor, thereby achieving overall regulation and on-demand distribution.

In order to solve this problem, the environmental protection field has proposed a solution for flue gas desulfurization and denitrification. The basic principle is to use strong reducing chemical agents such as ammonia water to undergo oxidation-reduction reactions with acidic gases such as nitrogen oxides in the flue gas under specific temperature and pressure conditions, ultimately forming harmless nitrogen gas that is then discharged into the atmosphere to solve pollution problems.

Partition metering, also known as regional management, is the process of dividing the existing water supply network into several relatively independent sub regions according to certain principles, in order to achieve separate metering of water consumption in each region. ”DMA (District Metering Area) refers to the establishment of several relatively independent metering areas in the water distribution system by installing flow meters or water meters, closing some valves, and taking into account natural geographical features such as urban terrain and landforms, administrative divisions, water pressure distribution, water plant distribution and supply capacity, number of water meters, and water usage according to certain principles.

With the rapid development of the gas industry and the accelerated integration of new technologies and gas business, a modern digital energy service system is being constructed. Gas big data analysis based on intelligent metering and smart pipeline networks is helping enterprises provide customers with more accurate and diversified energy services. Realizing the "dual carbon" goal, the digital transformation of the gas industry also faces opportunities and challenges

The gas pipeline inspection system is mainly an inspection management system based on GPS, GIS, and GPRS applications. The system closely integrates GIS information of gas pipeline network and its ancillary facilities with pipeline leak detection equipment and inspectors, which can quickly provide real and accurate gas pipeline network data, and achieve functions such as rapid leak detection, real-time uploading, area division, real-time trajectory accurate positioning, etc., providing reliable and uneducated basis for daily management, analysis and statistics, safety prediction, etc. of outdoor gas pipeline network.

The leakage loss in urban water supply networks not only increases the cost of water production and leads to continuous increase in water supply, resulting in significant economic losses, but also causes serious hazards such as air collapse and damage to building foundations. There are many main reasons for the leakage of urban water supply networks. Exploring the main reasons for the leakage of urban water supply networks and strengthening the leakage detection of water supply network systems.
