CORROSION-RESISTANT FLOATINGSENSORS FOR TANK LEVEL CONTROLSINGLE- & MULTIPLE-POINT LEVELSENSING WITH SINGLE FLOATFEATURES• These liquid-level sensorsprovide simple, troublefreeliquid-level control.The switch is housed insmooth, chemical-resistantthermoplastic casing and issuspended on its own cable.As the fluid level rises, thesensor tilts, and the switchcloses to start or stop apump, open or close a valveor actuate indicator lights asrequired. These sensors areeasy to install—they workeven in solids and scum.• Operates in almost anyliquid.SINGLE-LEVEL• Multiple-level switches inone device.• Overcomes turbulenceeffects.• Immune to adverseenvironment.• No fixtures needed in tanksides.• Simplifies control circuitrywith different versions.• Switching levels easilyadjusted.• Simple to install.• Requires no maintenance.• Low-cost, proven reliability.• These switches work equallyas well with valves as theydo with pumps.Standard series shown above with new mini series level sensors.HOW IT WORKS: The floating switch follows the liquid-levelmovement. As the level varies, the float inclination changes toactuate switches encapsulated in the Polypropylene cone.
