ABSTRACT:
A flow meter having a scale with temperature set points corresponding to a flow rate that a known fluid flowing therethrough at the set point temperature must reach to ensure turbulent flow of the fluid through a cooling system of a specified diameter. The flow meter preferably includes a plurality of scales, each having temperature set points corresponding to a different sized passageway in the mold cooling system. The scales are printed on a sleeve, rotatably mounted on a cylindrical body of the flow meter. The scales are selectively rotated into view by an operator to permit the operator to use the appropriate scale corresponding to the diameter of the passageways of the cooling system with which the flow meter is to be used.
