Operating Principle

The KENCOMagna-Site*TM is a magnetic liquid level indicator used to determine the volume of liquid contained within a vessel. Because the Magna-Site*TM eliminates the need for glass, high pressure applications and hazardous locations are protected from the danger of a chemical spill due to glass failure.

The KENCO Magna-Site*TM utilizes three major components: the gauge housing chamber, the magnetic float and the magnetic flag assembly.

The gauge housing chamber is mounted adjacent to the side of the vessel. It is constructed to withstand the same temperatures and pressures as the tank itself. It is equipped with the appropriate tank mounting connections for easy installation and to allow equalization of liquid level in tank and gauge.

Inside the gauge housing chamber is the magnetic float, which contains radially-positioned magnets to provide a 360 degree magnetic-flux field. Each float is internally weighted based on specific gravity so that the liquid level in the gauge coincides with the location of the magnets inside the float.

Attached to the gauge housing chamber is the magnetic flag assembly This is the visual means of liquid level indication for the KENCO Magna-Site*TM. The assembly is made up a of a series of bi-colored fluorescent flags. As the magnetic float rises and falls with the liquid level in the gauge housing chamber, a magnet embedded in each flag reacts to the 360 degree magnetic flux of the float. This repelling magnetic force causes each flag to rotate 180 degrees. The flags below the magnetic flux of the float will flip to fluorescent green, while those flags above the float level remain steel gray.

When your application priorities are safety, visibility and accuracy, the KENCO Magna-Site*TM is the low-maintenance, cost-effective solution. Back To Top

Gauge Features

Gauge Features Maximum safety -- No glass is used in the construction Optimum visibility -- Fluorescent flags are visible from great distances Float with 360 degree magnetic flux -- Maintains a strong magnetic field in all directions; turbulent liquids will not cause flag assembly to give an inaccurate level indication Double flag protection -- Flags are hermetically sealed inside a PTFE encapsulated assembly which is shrouded by a 300 series stainless steel enclosure on three sides with a UV stabilized high-impact clear polycarbonate shield Adjustable viewing angles -- Flag assembly can be rotated to any angle to provide maximum visibility Multiple mounting options -- Engineered construction allows for a variety of mounting configurations Compatibility -- A broad range of materials  can be used to withstand harsh chemicals Remote level indication -- Explosion-proof magnetostrictive level sensor/transmitter provides a 4-20mA signal output Height scale -- 304 stainless steel with no. 3 finish and large etched characters/lines for easy reading High/Low level switches -- Explosion proof switches can signal an alarm, operate a pump/valve or act as an emergency shut down Convenience -- Easy installation and very low maintenance Warranty -- Three year guarantee against defects Reliability -- KENCO has been building magnetic liquid level indicators since 1986.

MagnaSite Float and Flag Assembly

Float Characteristics 360 degree magnetic-flux field provides constant interaction with flag assembly in turbulent liquids Internally weighted based on specific gravity so that location of magnets inside float coincide with liquid level in gauge Cylindrical geometric shape ensures more accuracy in interface specific gravity applications Rare earth magnet assembly has an unusually high energy output volume and is highly resistant to demagnetization; they will not demagnetize at high temperatures like ceramic magnets Standard float material is 316 stainless steel Other float materials available, including titanium, hastelloy™, monel™, inconel™, alloy 20, aluminum, pvc and cpvc Standard float good to a minimum specific gravity of 0.50 Maximum working pressure is 1200 psig Maximum operating temperature is 550 degrees Fahrenheit 360 degree magnetic-flux field is ideal for interaction with KENCO magnetostrictive transmitter Float is non-vented, so vapors can not condense inside float Compact length minimizes ground clearance requirements

Flag Assembly Fluorescent flags for maximum visibility No glass in flag assembly Shield is UV stabilized high-impact clear polycarbonate Chamber is hermetically sealed and nitrogen filled to prevent internal condensation and ensure 100% flag rotation every time Totally enclosed with clear F.E.P. PTFE tubing for maximum chemical resistance 300 series stainless steel enclosure provides maximum protection from puncture of F.E.P. PTFE tubing 300 series stainless steel is more compatible to corrosive environments than aluminum Double o-ring seal assures that the flag assembly will not lose its nitrogen-filled atmosphere Each flag contains an Alnico 8 magnet, making each flag highly resistant to demagnetization Flags are UV stabilized, high-temperature thermoplastic and molded in color to prevent facing No ceramic magnets are used Maximum constant temperature of 350 degrees Fahrenheit Back To Top
