What is the development trend of vortex flowmeter?

1. Develop towards high performance and high accuracy

The emergence of digital technology has improved the accuracy, resolution and measurement speed of analog instruments by several orders of magnitude, laying a good foundation for the realization of test automation. The introduction of computers has brought about a qualitative change in the function of instruments, from the measurement of individual parameters to the measurement of characteristic parameters of the entire system, from simple acceptance and display to control, analysis, processing, calculation and display output, and from measurement with a single instrument to measurement with a measurement system. The improvement of the technical indicators of vortex flowmeters is the pursuit of industry development, such as the measurement range, resistance from superconducting to 1014Ω, and temperature from near zero to 1010℃. For example, in terms of measurement accuracy, time measurement has increased from 1 second in 300,000 years to 1 second in 6 million years.

2. Pursue high stability and high reliability

With the continuous expansion of the application fields of instruments and measurement and control systems, reliability technology plays an important role in maintaining normal operation in large-scale projects and industrial production such as aerospace, electric power, metallurgy, and petrochemicals. The vortex flowmeter that ensures the normal operation of the measurement and control system of on-site instruments also requires high stability and high reliability. Due to the emergence of new materials and the development of various processing technologies, the reliability of modern vortex flowmeters has increased by 3 times in terms of mean time between failures compared to 10 years ago.

3. Miniature and portable

The application of vortex flowmeters has gone beyond the laboratory. Whether it is on-site calibration or the actual needs of environmental protection, portable vortex flowmeters are needed.

New very large scale integration (VLSI) devices, micro-electromechanical systems (MEMS), wafer scale integration (WSI) and multi-chip modules (MCM), etc.; the use of micro-control technology, micro-machining technology, micro-detection technology, micro-light source, micro-spectroscopic optical system, micro-sensors, etc., make it possible to reduce the size of vortex flowmeter products and improve their accuracy.
