ASYMMETRICAL DISPLACEMENT FLOWMETER

摘要

An asymmetrical displacement flowmeter comprises a streamlined body or assembly (1) which floats or is submerged in liquid (3) and is subject to frictional and dynamic pressure forces caused by liquid flow and tilts about axis (9) near the leading end of the body being anchored relative to the flow through tie (7) and anchor (6) or other means acting through axis (9). Degree of tilt from the vertical of body (1) about the axis is affected by the gravity restoring moment acting about the axis and can be adjusted by movement of weight (14) within the body. Pointer (12) attached to pendulum (13) about axis (9) indicates velocity of flow on scale (2) attached to body (1). In open channel depth is measured on scale (11). In closed conduit, body rotates about shaft through wall and may be folded during installation. Velocity and depth may be transmitted electronically.
