FMU850 IP68 Tube-Segment Ultrasonic Flow Meter

Ultrasonic flowmeter is a non-contact instrument, which can measure the flow of medium with large diameter and can also be used for the measurement of medium that is not easy to contact and observe. Its measurement accuracy is very high, and the external clip-type installation can reach the highest accuracy of ±0.5%. It is almost not disturbed by various parameters of the measured medium, especially it can solve the strong corrosiveness, non-conductivity, Flow measurement of radioactive and flammable and explosive media.
FMU850 IP68 tube-segment ultrasonic flow meter is based on the principle of “velocity difference method” to measure the liquid flow in the circular tube. It adopts advanced multi-pulse technology, signal digital processing technology and error correction technology, which makes the flow meter more suitable for the environment of the industrial site, and the measurement is more convenient, economical and accurate. The products have reached the advanced level at home and abroad, and can be widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage and other fields.
