Matters needing attention when debugging the gas flowmeter

On the one hand, the development of gas flow meter technology has become increasingly mature, and the level of gas flow meter production and research technology in my country is not lower than the international advanced level. On the other hand, although the regions of my country's flowmeter manufacturers are mainly concentrated in Jiangsu, Zhejiang and South China, the quantity is relatively large, and the quality of their products varies greatly. This is the result of 'the threshold is not high', but also the reason. However, some property staff do not know that during installation, the heating unit is re-tested, which may cause changes in parameters and increase costs. The roundness of the pipe is not good, the inner surface is not smooth, and there is pipe lining scaling. This is possible if the pipe material is cast iron pipe. Solution: Choose a place with smooth inner surface pipe material or lining such as steel pipe. The establishment of this standard effectively guarantees the accuracy and reliability of the calorific value, safeguards the legitimate interests of both heating companies and users, and also greatly promotes the development of energy conservation and consumption reduction in the city. , cost accounting, energy balance and statistical analysis of energy utilization and other work to provide a strong guarantee. The senior administrator of the operating system has the function of remote control and one-key recovery. One-button recovery, all traces disappear, and the remote control socket is a small box with a small black antenna installed behind the secondary steam flow meter. Therefore, please note that after the personnel of the Quality Supervision Bureau arrive at the scene, they must first remove the remote control socket behind the secondary meter and then send electricity to check the parameters. In this way, the adjusted parameters are stored in the secondary meter chip, and the traces cannot be eliminated. This result is related to the current situation of regional economic development in our country. Nationally, the economies of the above three regions are relatively developed, various economic entities are relatively concentrated, and the consumption level of residents is relatively high. The market promotion methods adopted by the manufacturers of gas flowmeter products are mainly 'establishing corporate websites' and 'magazine advertisements'. In addition, most manufacturers of gas flowmeter products do not set up branches or offices in various regions and cities, and the sales channels are mainly based on direct sales from manufacturers. The manufacturers of gas flowmeter products accepted in this survey are mainly small and medium-sized enterprises, with the number of employees ranging from 10 to 100. Secondly, nearly 50% of the manufacturers started producing flowmeter products before 1995, which has a long history. To a certain extent, this also reflects the technology and development of flowmeter products in my country. The flowmeter manufacturers interviewed in this survey generally believe that the technical level is more important in this industry, and that the industry threshold is not high. If a non-streamlined vortex generating body (bluff body) is set in the fluid, two rows of regular vortices will be generated alternately from both sides of the vortex generating body. This kind of vortex is called Karman vortex street. The ultrasonic gas flow meter was working fine, and suddenly the float gauge stopped measuring flow. Cause analysis: The measured medium has changed. Solution: Change the measurement method. The measured medium is vaporized due to excessive temperature. The solution: cool down. The temperature of the measured medium exceeds the limit temperature of the sensor. The solution: cool down. The couplant under the sensor is aged or worn out. Solution: reapply the couplant. Most of the manufacturers said that they have product R&D departments within their companies, and the research level is in the middle. The market regions of the interviewed gas flowmeter manufacturers are mainly in East China, North China and South China. The measured medium is pure or the suspended solids are too low. Solution: Select other suitable instruments. The gas flow meter sensor is mounted on a fiberglass pipe. Solution: remove the glass fiber. The sensor is mounted on the bushing, which attenuates the ultrasonic signal. Solution: Move the sensor to the unsleeved pipe section.
