VIZUAL® ® Magnetic Level Indicators DESCRIPTION Economic and simple Vizual® Magnetic Level Indicators (MLI’s) are built to be simple, rugged, reliable and cost-effective. Vizual indicators have basic features but are precision engineered and manufactured to guarantee a long lifetime. The Atlas® MLI’s are higher end gauges offering a wider choice of materials, special finishes, higher pressure and temperature ratings. MLI’s are widely used to replace sight and gauge glass indicators because these often require more maintenance. Optional switches and transmitters transfer the local level readings to a remote DCS/PLC system. For Atlas® gauges – consult bulletin BE46-138. F E AT U R E S • Rugged, shockproof and completely sealed for safety. • Rail can be rotated to obtain better viewing position. • One or more switches can be positioned on the indicator for separate alarm indication. • Immediate and accurate response to level changes. • Stainless steel flags in aluminium rail. • Float failure warning (optional): blue/white. • Standard 1/2" NPT vent and drain plug. • Max hydrotest pressure of the float 85 bar (1230 psig). • Max process temp. +160 °C (+320 °F) - optional to +400 °C (+750 °F). • Min process temp. -50°C (-60°F). • Measuring range up to 5,7 m (19 ft) – longer lengths at request. • Standard SG range from 0,56 - 1,50. • Floats are not vented nor gas filled. • Options: * scale in cm or tailor made * hermetically sealed and vibration resistant SPDT microswitches with silver plated contacts (gold optional). * reed type bi-stable switches * reed chain transmitter with 4-20mA output (HART® optional).

Worldwide level and flow solutions P R I N C I P L E O F O P E R AT I O N The MLI (Magnetic Level Indicator) consists of a sealed by-pass cage, a float containing a magnet and a visual indicator rail with bi-coloured flags that individually contain a magnet. The indicator rail is external mount on the cage and its flags are magnetically coupled/aligned with the magnet of the float. As the level changes, the float will follow and its magnet will attract the magnets in the flags. This will cause the flags to rotate showing their opposite coloured side. The same electro-magnetic coupling will activate/deactivate switches or change the output of an externally clamped on reed chain transmitter.
