The Glass float chamber containing a magnetic float which rises and falls with fluid level changes, is connected to the vessel wall. As the float moves in the chamber, its providing an indication of liquid level.
For added protection, the glass level tube may be protected with a transparent PVC screen.
High or Low Level Switches
Adjustable switches BSM 501 or BRK 60 (see page 585-01 and 585-02) are mounted to the exterior of the float, they are actuated by the magnetic field. Switches may be wired to indicate a high or low level, control pumps, valves, or in any intermediate position deemed important to the process. The bi-stable change-over high breaking capacity switch actuates and remains in the actuated position as the float rises past the switch. The switch returns to its initial position as the float lowers passing the switch.
