In industrial production and process control, flow meter is one of the most important instruments. As a common type of flowmeter, vortex flowmeter is widely used in various fields. Among them, DY type and CD type are two common models of vortex flowmeter, and there are some differences in principle, structure and application scenarios. This article will introduce the difference between DY type and CD type in detail, and provide you with a guide to choose a vortex flowmeter.

DY vortex flowmeter is a direct contact with the liquid measuring instrument. It uses a piezoelectric detection element, which can directly feel the dynamic pressure changes of the liquid flowing through. The CD-type vortex flowmeter is a non-contact measuring instrument, which uses an inductive detection element to achieve flow measurement by detecting the vortex in the liquid. Due to the use of different detection principles, there are differences in response speed, accuracy and applicable fluid between DY and CD.

in structure, DY type and CD type vortex flowmeter are also different. DY type vortex flowmeter usually adopts all stainless steel structure, which has strong corrosion resistance and is suitable for measuring various corrosive liquids. The CD type vortex flowmeter is often used plastic or alloy materials, lighter and has a lower cost. Therefore, in the use of the environment is more harsh or need to use for a long time, DY type vortex flowmeter is more suitable; and in some general industrial applications, CD type vortex flowmeter can meet the requirements.

In addition, DY type and CD type vortex flowmeter also have certain differences in applicable scenarios. Because the DY type is measured in direct contact with the liquid, it is suitable for high temperature, high pressure or liquid flow measurement containing solid particles. Due to the non-contact principle, the CD type vortex flowmeter is suitable for a wider range of liquid flow measurement scenarios, including but not limited to industrial water treatment, chemical industry, petrochemical industry, food and beverage and other fields.

To sum up, there are some differences between DY and CD vortex flowmeters in principle, structure and applicable scenarios. Choosing a suitable vortex flowmeter requires comprehensive consideration of fluid properties, flow range, use environment and other factors. In the selection of vortex flowmeter, it is recommended to select the most suitable model and specification according to the specific application scenarios and requirements, combined with the characteristics and technical parameters of vortex flowmeter for comprehensive evaluation and comparison.
