1. What are the mainstream brands of imported steam flow meters? Currently, in public information, the mainstream brands of imported steam flow meters mainly cover top manufacturers in Europe, America, and Japan, covering mainstream measurement technology routes such as vortex street, Coriolis, and ultrasonic, and are suitable for steam measurement needs in different industrial scenarios.

1. Mainstream European and American Brands 1 Emerson in the United States: its Rosemount Vortex and Micro Motion Coriolis mass flow meters have high accuracy, strong anti-interference, and are suitable for saturated/superheated steam, making them a benchmark for high-end projects. E+H in Switzerland: Promass series Coriolis and Vortex flow meters, modular design, support for multi parameter measurement, and strong adaptability in food, medicine, and chemical scenarios. KROHNE in Germany: Optionic ultrasonic and OptiMASS Coriolis flow meters, with obvious advantages in large caliber and complex flow fields, and no straight pipe requirements. Spirax Sarco in the UK: expert in nuclear steam systems, SGM series gear flowmeter, stable saturated steam measurement, can provide a complete set of steam energy-saving solutions

5. ABB from Switzerland: differential pressure and bucket stop vortex flowmeter have stable performance and good compatibility with automation systems, widely used in power and metallurgical scenarios

6. Siemens from Germany: Strong integration capability for Industry 4.0, seamless integration with PLC/SCADA, suitable for smart factories and large pipeline systems

7. NOOK from Germany: Founded in 1885, NOOK is a pioneer manufacturer in the fields of valves, flowmeters, and water pumps in Germany

. Its flowmeter products are resistant to high temperature, high pressure, and corrosion, and are suitable for multiple industrial scenarios such as Kongsihu power station, petrochemical, and metallurgy

8. GAOK from Germany YLE Gail: Founded in 1975, we provide process automation and control equipment solutions, and our flowmeter products can adapt to complex industrial conditions.

2. Mainstream Japanese Brands 1 Yokogawa Electric of Japan: The DY series vortex flowmeter has excellent anti vibration performance, stable measurement at low flow rates (0.3m/s), and a high market share in Asia, suitable for flow fluctuation conditions. 2. Hitachi of Japan: As a veteran motor manufacturer in Japan, its valve and supporting flowmeter products cover semiconductor, industrial machinery and other fields, and can be adapted to industrial steam measurement scenarios.

2. What is the diameter of the vortex flowmeter pipeline?

The diameter of the outlet branch of the vortex flow counter varies from DN10 to DN1000. Generally, small diameter pipelines are installed in pipe sections, while large diameter pipelines are installed in plug-in silver channels..

3. What are the disadvantages of vortex flowmeters?

1. Poor anti vibration performance. External vibrations can cause measurement errors in vortex flowmeters, and even prevent them from functioning properly. The high flow velocity impact of the channel fluid will cause additional vibrations in the cantilever of the vortex generator, resulting in a decrease in measurement accuracy. The impact of larger pipe diameter is more significant. 2. Poor adaptability to measuring dirty media. The generating body of the vortex based flowmeter is ea
