Magnetic level indicators are an excellent alternative to gage glass indicators because they do not leak and offer excellent visibilty.  The float chamber is basically a column of 2-1/2 inch pipe with process connections to match those of the storage tank, reactor, or other equipment where level is to be measured. These connections may be side couplings or flanges, or top and bottom flanges.

The magnetic float moves up and down inside the chamber as the process level changes. Float type is determined by the process fluid, light enough to maintain buoyancy and have properties that allow it to withstand the temperature and pressure combination.

Contained inside the sealed float is a 360 deg. magnet assembly. The indicator tube and scale assembly are attached to the float chamber (standard scale is in feet and inches). The indicator tube is available in polycarbonate or glass (temperature limit on polycarbonate is 250 deg. F).

Features:

• Hermetically sealed indicator does not contact process fluid.
• Choice of mounting styles and special materials: stainless steel, CPVC, Kynar, Hastelloy, Monel and others.
• Safe for flammable, toxic and corrosive fluids at high pressures and temperatures.
• Ideal for interface measurement.
• FM, UL & CSA listed clamp-on alarm switches & 4-20mA X-mtrs.
• Welding specs to Boiler and Piping Codes ASME-B31.1 / B31.3. 3A
• Approved for sanitary service.
• Magnetic flippers or continuous follower.
• All floats with 360 Deg. concentric magnet assembly.
