Ultrasonic gas meters have been widely used in developed countries such as Europe, America, and Japan. With the issuance of the "JJF2012-2022 Ultrasonic Gas Meter Type Evaluation Outline" in China, it will be the trend for domestic ultrasonic gas meters to replace membrane gas meters. Compared with membrane gas meters, ultrasonic gas meters have the following advantages：
1) Equipped with temperature compensation function, achieving fair trading and reducing gas supply and sales transmission differences.
2) There are no moving parts, no wear, no aging, low maintenance costs, and higher reliability.
3) Long term accuracy remains unchanged, unlike membrane gas meters that experience a significant increase in error after a few years of use, resulting in increased charging losses.
4) It can measure small flow rates and use its leak detection capability to automatically alarm for gas leaks.
5) Wide range ratio, capable of covering the range of multiple models of membrane gas meters.
6) Can achieve bidirectional flow measurement, membrane gas meters can only measure in one direction.
7) Small in size, easy to install in cramped apartments or centralized meter areas.
8) Low pressure loss, can greatly reduce the cost of boosting long-distance pipelines, fully electronic, and low after-sales maintenance costs.
9) Equipped with encrypted anti-theft function, anti-theft gas, anti-interference, and high security.
10) High level of intelligence, with multiple safety alarm functions, more suitable for the needs of safe gas use.
11) The Internet of Things has flexible access and can be flexibly adapted to gas meter standards and automatic meter reading management systems in different countries and regions.
Question 1: What are the advantages of ultrasonic gas meters compared to membrane gas meters?
Answer: Ultrasonic gas meters have the following advantages:
1) Ultrasonic gas meter is an electronic measuring instrument that has no rotating parts, no wear, no aging, and a long service life.
2) Equipped with temperature compensation function, achieving fair trading and reducing gas supply and sales transmission differences.
3) Long term accuracy remains unchanged, unlike membrane gas meters that experience a significant increase in error after a few years of use, resulting in increased charging losses.
4) It can measure both small and large flow rates, and automatically close the valve in case of gas leakage or pipe explosion, ensuring high safety.
5) Wide range ratio, capable of covering the range of multiple models of membrane gas meters.
6) Can achieve bidirectional flow measurement, membrane gas meters can only measure in one direction.
7) Small in size, easy to install in cramped apartments or centralized meter areas.
8) Low pressure loss, can greatly reduce the cost of boosting long-distance pipelines, fully electronic, and low after-sales maintenance costs.
9) Equipped with encrypted anti-theft function, anti-theft gas, anti-interference, and high security.
10) High level of intelligence, with multiple safety alarm functions, more suitable for the needs of safe gas use.
Question 2: Is ultrasonic gas metering technology mature? Is it safe? Does the country encourage promotion and use?
Answer:Ultrasonic gas meters have been widely used in developed countries such as Europe, America, and Japan. Due to the fact that ultrasonic gas meters can measure both small and large flow rates, they automatically close the valve in case of gas leakage or pipe explosion, resulting in high safety. China officially began implementing the "JJF2012-2022 Ultrasonic Gas Meter Type Evaluation Outline" on June 27, 2023, and replacing membrane gas meters with ultrasonic gas meters will be the trend.
Question 3: What is the cost-effectiveness of ultrasonic gas meters compared to membrane gas meters?
Answer:At present, the price of ultrasonic gas meters is slightly higher than that of membrane gas meters, but the supply and sales difference is smaller. Gas companies have a much higher cost-effectiveness in long-term use than membrane gas meters. Meanwhile, due to its high safety, gas companies have lower operational risks.
Question 4: What are the benefits of using ultrasonic gas meters for residential users?
Answer:Due to its ability to measure both small and large flow rates, ultrasonic gas meters automatically close valves in the event of gas leaks or pipe bursts, providing high safety and better protection for the lives and property of residential users. At the same time, ultrasonic gas meters have a beautiful appearance and are currently installed in some high-end residential areas or villas in China to improve the quality of residential areas.
Question 5: Can residents install ultrasonic gas meters themselves?
Answer:According to relevant regulations, it is illegal for residents to dismantle gas pipelines or equipment without authorization, and gas pipelines or equipment can only be installed by personnel with relevant qualifications. Residential users often want to purchase ultrasonic gas meters themselves and request gas companies to replace them. However, due to the incompatibility of remote meter reading systems from different gas meter manufacturers, the same brand of gas meters is usually used in the same community. It is an actionable way for residential users in the community to negotiate with the gas company to exchange meters by paying the price difference.
