DESCRIPTION
BS ISO 3354:2008
This standard BS ISO 3354:2008 Measurement of clean water flow in closed conduits. Velocity-area method using current-meters in full conduits and under regular flow conditions is classified in these ICS categories:
- 17.120.10 Flow in closed conduits
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:
the velocity distribution is regular (see 6.1.2);
the fluid is water which is clean or considered to be clean1);
the conduit is full;
the flow is steady2).
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.
