Liquid Flow Measurement in Open Channels - Velocity-Area Methods
This National Standard of Canada is equivalent to International Standard ISO
This International Standard specifies methods for determining the velocity and
cross-sectional area of water flowing in open channels (with or without ice
cover), and or computing the discharge therefrom.
It covers methods of employing current-meters and floats to measure the
velocities. Although, in most cases, these measurements are intended to
determine the stage-discharge relation by means of readings at several stages,
this International Standard deals only with single measurements of the
discharge; the continuous recording of discharges over a period of time is
covered in ISO 1100.
NOTE - Measurements for the purpose of determining the discharge in efficiency
tests of hydraulic turbines are specified in IEC Publication 41, International
code for the field acceptance tests of hydraulic turbines.
