A float containing magnets, moves up & down with changing liquid level, in a non-magnetic - non-fragile chamber.
“Indicap follower” or “Bicoloured Rotocyls” indicate level externally. The “Indicap Follower” moves within a glass tube filled with water. Water makes the capsule weightless and reduces friction. The indication is continuous.
The “Bi-coloured Rotocyl” system comprises of series of bicoloured cylinders that hold each other by tiny magnets within. As the strong magnet of the float moves behind them, they turn inside out. Level is indicated as rising bar of yellow. In contrast empty space above is seen as black. Resolution limited by Rotocyl width
MOC: CS, SS, PP, PVDF
Operational Pressures: Abs. Vacuum to 30 Bar
Operational Tempreture:-50o to 300oC
Range:300-6000 mm:
Ultimate Safety: No glass breakage, no gland leakage. The non-fragile chamber of metal or plastic eliminates messy and hazardous spills.
Excellent Visibility: Designed for colourless, transparent or even tarry black liquid. Indication is clearly visible from over 30 meters
Simple, Economical & Maintenance Free: : In reflex transparent Gauges, the number of joints, glasses, nut bolts, valves and other parts call for cumbersome maintenance and involve high investment and running cost. In contrast, Magnetic Indicators are maintenance-free and hence very economical

Working: A magnetic float (for side mounted magnetic level indicator) or a magnetic tip (for top mounted magnetic level indicator) moves in a chamber on which the sensor is mounted. Magnetically operated reed switches connected to a string of resistors, sense the level signal. The sensor resistance varies in proportion to level. This is converted into 4 to 20 mA current by the Loop Powered Transmitter. LCD display(optional) locally shows the reading
