Application and function
The flap indicator serves as indicating medium for the magnetic level gauge. It consists of anodized special section made of aluminium with movable stainless steel flaps. The flaps are protected against dust and spray water by a glass plate. The flaps (height = 10 mm) are painted white on one side and red on the other side. The red side of the flaps indicates the level. The indicating ledge can be turned into any direction as far as the process connection studs allow.
