Magnetic level gauges are installed in the tanks in various ways, where it is supposed to measure the level of the liquid. The fl oater in the by-pass tube moves up and down with the fl uid based on the principle of communicating vessels. The movement of the fl oater makes the bi-color magnetic disks placed in the aluminum profi le to rotate around themselves. The magnet in the floater is situated at the same level as the liquid regarding the immersion depth of the fl oater. Thus the bi-color magnetic disks, which colors visible from outside are changed by the floater, indicate the liquid level exactly and precisely. The color of the magnetic disks, as seen from the outside, begins to turns to red when the liquid level ascends, and conversely turns to white when it descends. In this way the liquid level in the tank can be monitored correctly. Magnetic level gauges can also be used in automation systems as a data input device. The liquid in the tank can be monitored by height of the liquid level, the volume of the liquid in the tank, etc. Using switches equipments like pumps, solenoid valves, etc can be controlled. The information of liquid level can be transmitted to the automation systems by connecting a series of reed-switches and control panel hardware to the magnetic level gauges.

Level Sensors & Switchs
Level sensors consist of a stainless steel floater sliding along a stainless steel pipe, and various control panels. They can be manufactured at various lengths in accord with user requirements. The working principle of magnetic level sensors can be summarized as follows: Reel-switches having been placed in the stainless steel pipe are stimulated by the magnetic fl oater, and this stimulus is transmitted to the control panels. Equipments like pumps, solenoid valves, etc can be controlled with these signals. In addition to these, the change of the liquid level in the tank can be monitored through the digital display as %, liters, etc. by transmitting these signals to the digital control panels, and to the automation system via 0-10V or 4-20mA analog the interface.
