The float level gauge consists of a float, a plunger, and other components. The float ball level gauge is installed on the top of the container through a connecting flange. The float ball root float ball level gauge LV55 floats on the liquid surface based on the principle of equal volume of discharged liquid. When the liquid level of the container changes, the float ball also moves up and down. Due to the magnetic effect, the dry spring of the float ball level gauge is magnetically attracted, and the liquid level position is changed into an electrical signal. The float ball level gauge displays the actual position of the liquid digitally through a display instrument, thus achieving remote detection and control of the liquid level.
