GB/T 21699-2008 Verification/calibration method of rotating-element current meters in straight open tank
Abstract
This standard specifies the principles, equipment, procedures, methods, certificates, materials, and acceptance of the flow velocity meter calibration tank (hereinafter referred to as the "calibration tank") for the calibration/verification of rotary flow velocity meters. This standard applies to the calibration/verification of rotary flow velocity meters, including propeller-type and cup-type flow velocity meters used for measuring velocities in open channels, and micro-rotor-type flow velocity meters used in laboratories.
