magnetic level indicator model MLR Column of colored rollers indicate the level in the tank Badotherm magnetic level gauges are designed for gauging liquids where glass, gaskets threaded connection etc cannot be tolerated because of corrosion problems, toxic gases, dangerous fluids etc. Model MLR features a column of magnetic rollers which are white on one side and red on the other. The rollers are made from plastic with a distance of 10 mm between the axes. As the float moves up or down the bunched field of the permanent magnet mounted in its top section pulls the rollers through a rotation of 180 degrees, thus changing color. As the float rises, the rollers are turned from white to red and as the float falls, they are changed back to white again. This model can be used with alarm switches and a transmitter with 4-20 mA output. The chamber on which the indicator is mounted must be of a non magnetic material. The standard is AISI316 but can also be supplied in PP, PVDF, PVC etc on request. level instrumentation For technical data sheets and dimensional drawings please refer to our website www.badotherm.com 303 01/01/2006 rev 2 Technical specification Cage 2” NB pipe AISI316 / PP / PVC / PVDF Maximum center to center 6000 mm ( side / side ) Depth 3000 mm ( top ) Connecting flanges ANSI B16.5 / DIN / JIS Maximum viscosity 500 cst Pressure rating PN16 … PN100 Maximum operating temperature 300 °C for AISI316 80 °C for PVDF 60 °C for PP 40 °C for PVC Minimum SG of liquid 0.40 Roller inaccuracy 1% Minimum difference in SG between interface liquid 0.10 Accessories and specials Alarm switches Transmitter 4-20 mA Interface measurement Heating jackets Drain / vent / isolation valves Float sink indication Salient features Un-pressurised float without mechanical or magnetic guide rails 360 degrees magnetic coupling Fully corrosion resistant system Not affected by pressure, vacuum, temperature foam and viscosity Minimum sensitivity to density variation Glandless construction Permanent indication without external power supply Fully adjustable limit switches Eccentric drain can not be blocked by the float Safe environmentally friendly and trouble free construction * for special applications consult factory 5.1.1
