| Abstract: | In order to demarcate the measurement precision of UF-911 multi-path ultrasonic llowmeter, a model test lot a factual pumping station and a precision demarcation test are performed with static cubage method at the National Water Flowmeter Calibration Station. The calibration procedure, measured data and error are analyzed briefly. The laboratory calibration for ultrasonic flowmeter and relative problems are discussed, which is instructive for practical proiects. |
| Keywords: | ultrasonic flowmeter measurement precision laboratory calibration |
