Abstract
The rotameter principle was used for the accurate measurement of the rate of flow of fluids. The rotameter is a small float within a tapered glass tube. The pressure drop across the float is constant. Increasing flow rates cause the float to take higher positions in the tube; and, thereby, provide greater flow areas. Rotameters calibrated for fluids of different sp. gr. are available. The range of the meter is between 5 and 50 ml./min. Quantities as low as 0.2 ml./min. can be measured accurately.Keywords
