The NIVOFLIP is a bypass level indicator for pressurized vessels up to 5.5 m height containing liquids. The welded bypass chamber that is the body of the indicator and the tank form one pressurized system. Mounted on suitable connection flanges located on the side of the tank the liquid level in the bypass tube and the tank is equal. A float in the bypass tube incorporating a polarized magnet tracks the level of the liquid. Bi-coloured magnetic flaps mounted on the tube composing a bar are serving as visual indicators by changing their colour as the float passes. The rotated magnetic flaps represent the actual level. The lower 100 mm of the bottom section of the indicating bar hasdifferent colouring providing for an optical error signal in case the liquid level drops below the lower connection point of the instrument. NIVOFLIPcan be equipped with optional limit switches or with NIVELCO's NIVOTRACK M L-500high precision magnetostrictive level transmitter if level transmission is needed. All optional units are operated via magnetic coupling, there is no direct contact with the measured medium
