一、概况应用匈牙利物理学家冯·卡门(Von-Karman)流体旋涡力学原理与电子检测技术(如压电、光电、电容、磁电、热敏、热丝、应变片和超声波等),制造成的一种新式计量仪表—旋涡流量计,已较广泛地用于工业现场。由于旋涡流量计比之常用的各类流量计,在性能方面有突出的优点(见表1)。因此,近年来在国外普及迅速,成为发展前景宽广、大有取代传统流量计趋势的新式节能计量仪表。
First, the general application of the Hungarian physicist Von-Karman fluid vortex mechanics and electronic detection techniques (such as piezoelectric, optoelectronic, capacitive, magnetic, thermal, hot wire, strain gauges and ultrasonic, etc.), manufacturing Into a new type of measuring instruments - vortex flowmeter, has been more widely used in industrial field. As the vortex flowmeter than the commonly used types of flowmeter, there are outstanding advantages in performance (see Table 1). Therefore, in recent years, the rapid popularization in foreign countries has become a new energy-saving meter that has broad prospects for development and greatly replaces the trend of traditional flow meters.
