This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.
In fact, in some product fields, the performance and function of our independently developed products have reached international standards.But our domestic steam flow meter is slightly inferior in terms of reliability and adaptability.
In the future, we should continue to improve the reliability and adaptability of our products. Only in this way, domestic steam flow meters can have more and more stronger international competitiveness.
