The trade war has been going on for a year now, and it is becoming increasingly fierce. How long will it continue in the future? Unknown. In this regard, we need to change the concept of long-term dependence on imported high-end instruments and strongly support the use of domestically produced high-end instruments. In fact, after more than 30 years of reform and opening up, we have digested and absorbed, continuously innovated, and in some watersheds or products, they have reached international standards and can completely replace imports. The cost-effectiveness is relatively high, the supply period is short, and the service is good. So, do we still need to rely on imported products?

Especially in the trade settlement of the steam to water heating industry, it is necessary to use a large number of imported ultrasonic flow meters with accurate measurement on high-temperature water. Although there are many well-known flow meter manufacturers in China, there is still a gap in product performance compared to international major brands, which cannot be comparable to imported products.

In order to address this weakness, the technical personnel of Weifang Aobo Instrument have independently developed the "dual channel ultrasonic flowmeter" for more than 3 years. After being tested by professional institutions such as the National Flow Verification Station and the Provincial Institute of Metrology Science, all indicator parameters and performance meet the standards of "imported instruments", and have obtained multiple patents and 2 software copyrights.

This "dual channel ultrasonic flow meter" has been widely used by customers in the heating industry's automobile to water trade settlement, and has been recognized and praised, especially in terms of water leakage prevention, online convenient maintenance, anti-interference, anti bubble, etc. This product has won a special interview in the 580 issue of CCTV's "Quality" program and participated in major exhibitions in Beijing, Shanghai, Jinan, Henan, Qingdao, and received the attention of multiple professionals.
