LEVSEN Magnetic Level Indicator Series MLI consists of a float chamber, a float, and an external indication device. The float chamber is basically a column of 2 1/2 inch pipe made stainless steel or any non magnetic material with process connections to match those of the storage tank, reactor, drum, column or other equipment where level is to be measured. These connections may be side couplings or flanges, or top and bottom flanges. The float moves up and down inside the chamber as the process level changes. Contained inside the sealed float is a very strong magnet assembly.
The indicator tube and scale assembly is attached to the outside of the float chamber. Inside the transparent, hermetically-sealed indicator tube is a light-weight magnetized indicator. This indicator is magnetically coupled with to the float and moves up and down inside the indicator tube as the float moves up and down with the rising and falling of the liquid level in the vessel. The indicator is brightly colored and allows the operator to read the level from 100 feet away. The only moving parts are the float and the indicator. An optional Flapper/Roller style indicator is also offered.
The basic magnetic level indicator offers simple visual indication. By using the transmitter, a 4-20mA signal can be sent to a remote location for indication or control functions. Additionally, level switches can be added, external to the float chamber, for alarm or control. These switches can easily be moved up or down the chamber while not disturbing the process.
Levsen Magnetic Level Indicator MLI 33 with Flapper Style Indicator
A magnetic flapper assembly is attached to outside of float chamber. These bi colour flappers are white on one side and red on the other. As the float moves up and down the bunched field of the permanent magnet mounted in its top section pulls the flapper through of 180°,thus changing their colour. As the float rises the flapper are turned from white to red, and as the float falls, they are changed to white again This mean at any given time the amount of liquid in the tank is constantly represented by red column.
