Top mounted magnetic level indicator is particularly useful for continuous level measurement of liquid, which coagulate if stagnant liquids with high viscosity. It is ideal for liquids under high pressure & for those liquids, which are corrosive & hazardous in nature.
Top mounted magnetic level switches work on permanent magnet reed switch basis. The floats contain permanent magnets that move freely between their stops rising or falling with liquid level movement. The Magnet's field actuated the reed switch as the float moves while the stoppers restrict overrun and prevent the reed switch returning to its original position. Stopper positions should not be changed.
Top mounting displacer liquid level switches utilize a simple buoyancy principle and are suitable for simple or complex applications, such as high level alarm or control of multiple pumps and alarms. The liquid level movement changes the buoyancy force on a displacer suspended from a range spring. The force change on the spring causes it to expand or contract moving an attraction sleeve into or out of the field of the switch magnet, actuating the switch. It is ideal for foaming, surging, or agitated liquids, dirty liquids and storage vessel applications.
Top mounting float liquid level switch is a type of float switch. It is designed for top mounting on virtually any process or storage vessel. It utilizes a single switch mechanism and float. The buoyancy force of a process liquid on the float causes the float to move with the liquid surface. The movement of the float moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch. It is used in fuel storage tank, day tank and cooling tower applications.
