Flow Meters

The LU-EMF89 electromagnetic flowmeter is a high-performance intelligent flowmeter developed by our company using currently advanced design concepts and technologies at home and abroad. It has a number of domestic and international pioneering technologies, ensuring high accuracy, high performance and wide range from every detail such as design structure, manufacturing process and testing process. The LU-EMF89 electromagnetic flowmeter consists of an EMF89 converter assembled with various sensors such as 01, 02, 03, 05 and 06. The EMF89 electromagnetic flowmeter can be assembled into an integral or split structure.
