2. What professional qualifications should vortex flowmeter manufacturers possess?
Vortex flowmeter manufacturers need to possess the following professional qualifications to ensure product quality, technical compliance, and service reliability
1. The core function of the Certificate of Approval for Measuring Instruments (CPA certification) is to serve as the "admission certificate" for new measuring instrument products entering the market, proving that the product meets legal metrological requirements.
. Certification content: It is necessary to pass the review of the metrological administrative department of the State Council to confirm that the product type meets the requirements of the type evaluation outline. Usage permission: After obtaining the certificate, it can be sold nationwide and the CPA special mark and number can be marked on the product and packaging. Importance: Ensure that the measurement accuracy and stability of the flowmeter comply with national standards to avoid disputes caused by measurement errors. Scope of application of the special equipment production license (TS certification): If the vortex flowmeter is used in the field of steam and other special equipment (such as boilers and pressure pipelines), the manufacturer needs
