FM13 Metal Rotameter

Metal Rotameter detection part is by a vertical conical tube from the bottom up expansion and a conical tube along the axis can move freely up and down the float composition, the measured fluid from the bottom up through the conical tube and float formation of the ring gap, float up, the lower end of the differential pressure to form the float up force; when the float by the upper force is greater than the weight of the float immersed in the fluid, the float all over the rise, the ring gap area increases, the ring gap at Fluid velocity immediately drop, the float on the lower end of the differential pressure is reduced, the role of the rising force on the float is also reduced, until the rising force is equal to the weight of the float immersed in fluid, the float will be stable at a certain height. Float in the cone tube height and through the flow has a corresponding relationship.
