Top Mounted Level Measuring Instrument works based on Pascal'slaw and buoyancy principle is the upward force a fluid exerts on anobject. Magnetic Float is made in shape of the Sphere which restson the top of fluid surface and it keeps travelling in upward &downward directions as fluid level varies respectively. this floatmay be more than one depends upon the multi point switchingrequired, it provides high / low / multipoint switching bymagnetically actuated reed switches in the guide pipe of the
Side Mounted Magnetic Level Switch Operates using a float actingas a lever, which rise and fall with the change in level of the tankfluid. at end of the lever mechanism a isolated switch is actuatedby the rod having permanent magnets which triggers the limitswitch assembly. This can be used to operate audio / visual signals
