Abstract
A fluid measuring device comprises flow meter for measuring quantities of flow or flow rates of fluid and flow rectifiers arranged upstream and downstream of the flow meter, whose rectifier elements or cells are sized and positioned such that a ratio W.sub.1 /D of a smaller width W.sub.1 of the cells to an inner diameter D of a passage for the fluid is less than 0.2 and a ratio L/W.sub.1 of a distance L between the flow meter and the upstream flow rectifier to the smaller width W.sub.1 of the cell is within 5.ltoreq.L/W.sub.1 .ltoreq.25, thereby improving an accuracy of measurement without increasing losses of pressure.
