ULB Type glass level gauge is a local indicating instrument produced according to the principle of connector. The medium in the container was led to the glass level gauge, and the actual height of level can be read from the transparent glass. Cylinder type glass level gauge is a large-diameter glass level gauge, which is suitable for medium with high viscosity or strong bubbles. For low-temperature medium, glass level gauge can use anti-frost fins. Using the temperature gradient principle, add anti-frost fins on both sides of the window, and observe the liquid level through the anti-frost fins.

The UQK(S)-100 float level controller is connected to the storage tank or container through threads or flanges. When the liquid level changes, the float move with it, so that the magnetic steel at the other end of the rod swings up and down. The structure can be divided into normal (UQK) and self-checking (UQKS) type. The self-checking float level controller can monitor the movement of the inner float through the external handle, which brings great convenience to adjustment and maintenance.

UHC magnetic level gauge provides a safer, more reliable and more visible option than conventional glass level gauge. The float moves up and down with the change of level, and the float transmits the level signal through the coupling magnetic field, which divides into the local indication type and the remote transmission output type.
Chamber and float have a variety of materials and pressure-grade options and are suitable for complex process applications of current major operating devices.
