The establishment of modern science on the basis of modern industry, in essence, is an expanded scientific experiments, it has all the elements of modern science and basic features. Instrumentation and measurement techniques of decisive significance in such activities, they are the basis for production activities. The scale of modern industrial production far more than scientists in the laboratory of exploration activities, the need to focus on a variety of movement change is much more complex than laboratory, it is a multi-parameter system, it is only through instrumentation to understand the and control them. Passage of time, the passage of time. In human scientific exploration and production activities, instrumentation gradually formed a specialized discipline, and a specialized industry. It supports the society's technological progress, experimental and observational approaches to many areas of scientific exploration activities, and provide the necessary technical support for human and orderly production activities and normal social life. This change is an important symbol of civilization, progress, human labor and scientific characteristics.

Instrumentation science and technology inherited the rich legacy of human civilization. New discoveries of natural sciences, engineering technology, new inventions, constantly enrich its content, making it the knowledge of highly intensive, highly integrated disciplines. The instrumentation is to expand human horizons open up a new domain leading tools, always facing serious challenges, which itself is always in development never ending creation. , A feature that has been particularly evident in the contemporary. With the rapid expansion of the areas of human activity, the measurement object can not cope with traditional instrumentation has increased dramatically. With the deepening of the natural sciences to explore the activities, the instrumentation has a higher sensitivity and resolution. With the industrial production process to a higher accuracy, faster pace and development of more complex processes, the original sensor technology has been increasingly unable to meet requirements. Urgent need to explore new measurement principles and methods, need to break the boundaries of traditional sensor technology threshold, in the sense of the order of magnitude higher response speed and signal to noise ratio, need to go beyond the classical methods, new ways to obtain the signal. In many areas, the work of the instrumentation has been great changes in the instrumentation has become a core component of industrial production equipment, safety devices, social security system, large-scale high-speed means of transport, medical systems and defense engineering, has been with for all the work object integrated, intelligent vortex flow meter and their measurement object can not be separated in space, must obey the harsh conditions of field application, a strong vibration and shock, electromagnetic interference and substantial hot and cold drastic changes .
