Special equipment vortex flowmeter
Qingdao Hesheng Measurement and Control Special Equipment Vortex Flow Meter Welding Material Selection and Standards: Welding material execution standard NB/T47018-2017 Pressure Equipment Welding Material Ordering Technical Conditions, welding material grade H08Cr21Ni10Si. When selecting welding materials, the specifications of the welding materials are determined based on parameters such as the length, width, and welding level of the weld seam. When installing a clamped vortex flowmeter on a horizontal pipeline to measure gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed at a higher position in the pipeline. Later, major instrument manufacturers in China also participated in this work. In the mid-1970s, Tianjin Industrial Automation Instrument Research Institute and the Automation Research Institute of the Ministry of Metallurgy also successively invested in the research and development of vortex flowmeters. An important milestone in the development of vortex flowmeters was the attention paid to product standardization by various countries. Developed countries such as the United States, Japan, and Germany have successively formulated and promulgated their own standards for vortex flowmeter products
