Device for measuring the volume flow of liquids

摘要

Device for measuring the volume flow of liquids, having a vertical measuring pipe (1) which has an outlet opening (7) in its shell (8). The measuring pipe (1) is closed at the bottom by a base (2) and is divided, partially and in the vertical direction, into an inlet chamber (3) which is open at the bottom and an outlet chamber (4) which is likewise open at the bottom. The inlet chamber (3) is partially covered and the outlet chamber (4) totally covered at the top by means of a baffle plate (5) inclined towards the inlet chamber (3). The outlet opening (8) is located in the region of the outlet chamber (4). The cross-sectional area of the outlet chamber (4) is at least twice as large as that of the outlet opening (7), and the cross-sectional area of the inlet chamber (3) is at least as large as the cross-sectional area of the outlet chamber (4). The free cross-sectional area between the bottom edge (9) - of the inlet chamber (3) and outlet chamber (4) - and the base (2) of the measuring pipe (1) is at least one and a half times as large as the cross-sectional area of the outlet chamber (4). With the device according to the invention, the volume flow of liquids in which gas beads or bubbles form or in which foam forms and/or the solid particles are present can be measured exactly; the corresponding dimensioning and structure of the device lead to optimal degassing of the liquid, and owing to the absence of movable parts in the device, no clamping of such parts can ...
