Abstract
PURPOSE: To make it possible to measure the quantity of flow covering a wide range by giving the variation rate of a flow-velocity-directional section by placing a dynamic pressure plate, provided in a flow tube, perpendicular to the flux direction and then by measuring the quantity of electricity obtained by converting from force, generated at a dynamic pressure plate, in proportion to the value of the velocity of flow raised nearly to two-third power.
CONSTITUTION: A fluid to be measured flows through tube 1, which is provided with dynamic pressure plate 2 having guide pin 3 and spring 4. On inside surface 8 of tube 1, a curved section-variable part is formed, so that dynamic pressure plate 2 is displaced according to the velocity of flow, the sentralized coefficient of dynamic pressure will vary. The dynamic pressure is transferred to electric load meter 6 via metal arm 5 and signals are extracted by cord 7 and amplified for a flow measurement. The flow measurement becomes possible covering a wide range by using simple structure and measurements of a fluid, gas, vapor, etc., can also be taken.
