摘要
大口径文丘里管逐台经过水流量标准装置标定,准确地给出了流出系数C值及其不确定度并使之可能达到±0.5％。20年来,用于调水、供水工程中,取得了成功,为ISO5167标准的扩大应用做出了有益的探索。
After having been calibrated by the standard water flow calibration rig, the large-sized Venturi tube can accurately give out the value of its flow discharge C and the uncertainty, and making the uncertainty possibly be at ±0.5%. Venturi tube has been applied successfully in diversion project and water project for more than 20 years, providing an useful survey for the extended application of ISO5167.
