Vortex precession flowmeter is a commonly used flow measurement instrument with the following characteristics:
1. High measurement accuracy
① Advanced principle: It is based on the Karman vortex street principle and the phenomenon of vortex precession in fluid mechanics for measurement, and determines the flow rate of the fluid by detecting the frequency of the vortex. This measurement method has high accuracy and stability.
② Digital processing: Advanced digital signal processing technology is used to amplify, filter, shape and other processes the weak signals detected by sensors, effectively improving measurement accuracy. Generally, the accuracy can reach ± 1% R, ± 0.5% R or even higher.
2. Wide measurement range
① Large flow ratio: The range ratio of the vortex precession flowmeter can usually reach 10:1 to 30:1, or even higher, which can accurately measure over a wide flow range and meet the flow measurement needs under different working conditions.
② Can measure multiple media: It can be used to measure the flow rate of various fluid media such as gas, liquid, and steam. For different media, accurate measurement can be achieved by setting and selecting appropriate parameters based on their physical properties and working conditions.
3. Low pressure loss
① Structural optimization: Its unique design of vortex generator and flow channel enables fluid to flow smoothly through the flowmeter, reducing pressure loss caused by fluid resistance.
② Significant energy-saving effect: In some systems that are sensitive to pressure loss, such as long-distance pipelines and low-pressure gas supply systems, the use of vortex precession flowmeters can effectively reduce the energy consumption of the system and improve energy utilization efficiency.
4. High reliability
① No moving parts: There are no movable parts inside the vortex precession flowmeter, so there is no risk of failure caused by mechanical wear, jamming, etc., reducing maintenance workload and costs, and improving the reliability and service life of the instrument.
Strong anti-interference ability: adopting advanced electronic technology and signal processing algorithms, it has strong anti-interference ability against external electromagnetic interference, vibration interference, etc., and can work stably in complex industrial field environments.
5. Easy installation
① Compact structure: The structure of the vortex precession flowmeter is relatively simple and compact, with a small volume and light weight. During installation, it does not require too much space or complex installation brackets, and can be directly installed on pipelines.
② Multiple installation methods: Various installation methods such as flange connection, threaded connection, or sleeve connection can be selected according to the layout and installation requirements of the on-site pipelines, and the requirements for installation position and direction are relatively low. It can be installed horizontally, vertically, or obliquely.
6. Equipped with data processing capabilities
① On site display: It is usually equipped with an intuitive LCD screen that can display real-time parameters such as fluid flow rate, temperature, pressure, etc., making it convenient for on-site operators to view and monitor flow data during the production process at any time.
② Diverse output signals: It can output standard analog signals (such as 4-20mA, 0-10V, etc.) and digital signals (such as RS485, HART protocol, etc.), making it easy to connect and transmit data with other devices, achieving integration of automation control systems.
