The UFK series magnetic levitation ball multi-point liquid level controller is a liquid level controller that can emit multi-point switch signals using one magnetic levitation ball. Dry reed switches are installed at different heights inside the conduit. When the magnetic levitation ball floats up and down with the change of liquid level, the magnetic steel inside the floating ball causes the electric shock of the upper and lower reed switches at the corresponding positions to be attracted or disconnected, sending out switch signals and having self holding function. Therefore, it is not afraid of power outage. After power restoration, the working state of the contact point can still reflect the true situation of the tested medium liquid level truthfully. The switch signal is divided into two types: Class A (normally open, instant closing) and Class B (normally closed, instant breaking) (depending on the movement of the float from bottom to top), which users can choose according to their needs.

Ordering Notice
Same as UQK type, dimensions such as L, L1, L2,... must also be specified.
Example of instrument selection:
UFK-3ASSB-1.36-1000（L1=50、L2=200、L3=800） Refers to a three-point alarm (signal output at liquid level heights of 50, 200, and 800), with an actual pressure of 0.6Kg. The material of the conduit, float, and flange is PVC, with a flange specification of PN1.0 and a medium specific gravity of 1.36. The ordered length is 1000
