Introduction

The vortex flowmeter is produced according to the Karman vortex principle. It is mainly used for the flow measurement of industrial pipeline fluids, such as gases, liquids, vapors and other media. The vortex flowmeter products developed and produced by our company are carefully built on the basis of comprehensively absorbing domestic and foreign advanced technology and years of research and development and production experience. The product has the features of advanced functions, low power consumption, simple structure, low resistance loss, stable operation, sturdy and durable, wide application, long service life and easy installation and debugging. There are analog standard signals and digital pulse signal outputs, which are easy to connect with digital systems such as computers. It realizes intelligent, standardized, serialized and generalized products, ensuring the quality and aesthetics of products. It is a relatively advanced and ideal measuring instrument.
