WORKING PRINCIPLE The reed switch relies on two basic scientific principles namely: buoyancy and magnetism. Buoyancy causes the float (which contains a magnet) to rise with the liquid and magnetism helps open and close the switch. A change in liquid levels raises or lowers the float up or down. The end of the pivot arm (non float side) contains a permanent magnet that can repel the switch magnet (inside the stationary ‘stem’ of the entire structure). The side mounted float level sensor (FF series) are manufactured specifically for horizontal mounting on tanks or vessels. They work well as...

IMPORTANCE FOR INSTALLATION 1. SUS304/SUS316 materials are not available for corrosive application. 4. Check the liquid’s S.G. level before installation. 2. The cable duct(s) must face downward to prevent moisture seeping in. 5. The mounting hole must be larger than the external diameter of the float. (Please refer to p2) 3. The float and extension rod must be inserted into the bin completely. 6. Don't mount the devices near the bin's inlet or outlet.
