DHE-FT Vibrating Level Switch is a control switch for level measurement developed and produced by DHE. This instrument combines the unique “ELL Signal Analysis Technology” and the leading manufacturing technology, which ensures the high reliability and durability of DHE Vibrating Level Switch. This product is suitable for level measurements in containers, storage tanks, tanks and conduits. Meanwhile, based on the design principle of detecting the change of vibration frequency when the fork is immersed in the medium, it is also suitable for the complex measurement occasions with turbulence, foam, vibration, bubble and viscous liquid.
