Withdrawn
This European Prestandard specifies the operational requirements, calibration and maintenance of propeller-type devices for the measurement of flow velocities in open channels. The requirements of the calibration facility are laid down. The result of calibration is the relationship between water velocity and rate of revolution of the propeller.
This European Prestandard does not define the form of the signal produced by the equipment or the signal receiving equipment.
