Do flowmeter maintenance companies need qualifications?

Required. According to the inquiry on the official website of the government, the necessary qualifications for flowmeter maintenance enterprises are the certificates for manufacturers to engage in normal production activities, including business license, type approval certificate for measuring instruments, special equipment production license (TS certificate), etc. They need to pass the assessment of the provincial quality supervision bureau and have been issued flowmeter maintenance qualifications, which require excellent qualifications.

2. Vortex flowmeter with pressure pipeline component license and special form testing report

Vortex flowmeter with pressure pipeline component license and special form testing report is a product that meets the mandatory requirements of national special equipment and has legal production and quality assurance qualifications.

. The specific explanation is as follows: Pressure Pipeline Component Branch Lead Dipper License (TS Certification). This license is a professional license issued by the State Administration for Market Regulation for special equipment production units, covering design, manufacturing, installation, and other aspects. For vortex flowmeter, the manufacturer must hold this certificate, indicating that it has legal production qualifications and the product meets the safety technical specifications of pressure pipeline components. For example, Qingdao Hesheng Measurement and Control obtained this certification in 2020, and the vortex flowmeter produced by them meets the mandatory national standards in the manufacturing process. The special form inspection report (special equipment superv

ision and inspection certificate) is issued by the special equipment supervision and inspection agency after inspecting the vortex flowmeter. It is issued for specific products to prove that their performance and safety indicators meet the requirements. This certificate is delivered to the user along with the product as a direct proof of qualified quality. For example, both Qingdao and Sheng Measurement and Controls vortex flowmeters provide this certificate to ensure that users receive traceable quality assurance. The necessity and compliance of selecting such products: The state imposes mandatory supervision on special equipment (including vortex flowmeters), and unlicensed production or use may lead to legal risks. Safety: Pressure pipeline components directly involve fluid transportation safety, and TS certification and testing reports can reduce hidden dangers such as leaks and explosions. Quality assurance: Products that have passed dual certification (manufacturer qualification+product testing) have more reliable indicators such as measurement accuracy and material durability. In addition to the above-mentioned certificates, high-quality manufacturers (such as Qingdao Hesheng Measurement and Control) may also hold ISO three system certification, which proves that the enterprises management, environment, and occupational health and safety systems comply with international standards. Type approval certificate for measuring instruments: Ensure that the measuring performance of the flowmeter meets legal requirements. Patents and software copyrights: reflect technological innovation capabilities, such as algorithm optimization, structural design, etc. Summary: When purchasing a vortex flowmeter, priority should be give
