Technical data Sheet 50466-615 July 2017 Flow meter Principle The instrument must be mounted in a vertical pipe with fluid circulation in the upwards direction. The self guiding cylindrical float is positioned inside a tapered tube. When the flow passes through the meter the float rises to a position of equilibrium where the weight of the float is balanced by the net force due to the fluid pressure. The float is magnetically coupled to a pointer indicating the rate of flow on the front scale. Applications The metal tube 250 series variable area flow meter is a specially designed instrument...
