FLUID VISCOSITY MEASURING DEVICE AND METHOD OF MEASURING FLUID-VISCOSITY

摘要

PURPOSE: A device for measuring the velocity of a fluid and a method for measuring the velocity are provided to simply measure velocity by using a method counting the number of channels in which a specimen takes in each single step channel array. CONSTITUTION: A device for measuring the velocity of a fluid comprises a fluid injection unit(10) and a channel array(33). The fluid injection unit comprises a first inlet and a second inlet. A first fluid is injected through the first inlet. A second fluid is injected through the second inlet. The velocity of the second fluid is known and the second fluid is not mixed up with the first fluid. The channel array is connected to the fluid inlets and a plurality of channels having the same unit cross sectional area is arranged by being spaced toward a direction across flowing directions of the first and second fluids.
