Two domestic steam meter studies passed acceptance

With the continuous development of the energy resource development market, the requirements for accurate measurement of steam flow have become more stringent. The two related approvals for the related steam flow device projects will promote the development of the steam instrument industry by leaps and bounds.

Recently, two scientific and technological plans for the "development of a condensing weighing method steam flow standard device" and "comparison of vortex street flow meters in a steam and air medium" undertaken by the AQSIQ project and the national steam flow metering station. The project passed the assessment and acceptance.

According to reports, entrusted by the Department of Science and Technology of the State General Administration of Quality Supervision, Inspection and Quarantine, the Shandong Provincial Bureau of Quality Supervision organized experts from seven institutions including Tianjin University, China Institute of Metrology, and Shandong University to form an appraisal committee. The expert group first conducted a laboratory on-site review, and then carefully listened to and reviewed the work report and related technical documents of the project team and conducted inquiries. After full discussion, the appraisal committee believes that the research results of the two projects are of good scientificity and practicality, and that the technical indicators are at the international advanced level and have unanimously agreed to pass the project acceptance.

It is understood that the "condensation weighing method steam flow standard device development" project developed by the condensate weighing method steam flow standard device verification flow range can cover (0-10) t / h, you can verify the instrument diameter DN25-DN300, Technology search, this device is the steam standard device with the largest steam flow verification capability in the world. "Vortex flowmeter in the steam and air medium in the comparison test" established a mathematical model of vortex flowmeter instrument coefficient conversion under different media conditions, filling in the research gap at home and abroad in this regard. The research results of these two projects have greatly improved the level of steam flow metering, will promote the development of the steam meter industry to achieve leapfrog development, and provide greater technical support for energy conservation and consumption reduction.
