Organization: ISO
Publication Date: 15 July 2008
Status: active
Page Count: 60
ICS Code (Flow in closed conduits): 17.120.10
scope:

This International Standard specifies a method for the determination of the volume flow-rate in a closed conduit by means of the velocity-area method using propeller-type current-meters under the following conditions:

a) the velocity distribution is regular;

b) the fluid is water which is clean or considered to be clean 1);

c) the conduit is full;

d) the flow is steady 2).

It deals in particular with the technology and calibration of propeller-type current-meters, the measurement of local velocities and the calculation of the flow-rate by velocity integration.

1) This method may be applied to other single-phase fluids but special precautions should be taken in this case.

2) The steady flows observed in conduits are in practice flows in which quantities such as velocity, pressure, density and temperature vary in time about mean values independent of time; these are actually "mean steady flows".
