电磁流量计是一种较新的感应式仪表,是根据法拉弟电磁感应定律的原理工作的。从五十年代起,荷兰、美国、日本开始研制现代工业上应用的电磁流量计,目前国外电磁流量计口径系列最小为φ2毫米,最大为φ2400毫米。在文化大革命期间,我厂开始研制大口径LD-900电磁流量计。1974年以来,
Electromagnetic flowmeter is a newer inductive instrument, is based on the principle of Faraday’s law of electromagnetic induction work. Since the 1950s, the Netherlands, the United States and Japan have started to develop electromagnetic flowmeters for modern industrial applications. At present, the minimum diameter of a foreign electromagnetic flowmeter series is φ2 mm and the maximum is φ2400 mm. During the Cultural Revolution, our factory began to develop large-caliber LD-900 electromagnetic flowmeter. Since 1974,
