The Zhejiang Provincial Metrology Institute undertook two research tasks of the â€œdevelopment of automatic non-disturbing solid material volume measurement deviceâ€ and â€œdevelopment of radar velocity measurement instrument on-site speed measurement error verification method and deviceâ€.
"Automatically non-disturbing solid material volume measuring instrument" is an important part of the high-accuracy high-quality parameter measuring device. The accuracy of the measuring device is better than six ten thousandths, and the high-accuracy of the quality parameter in the torque measuring instrument for high-end power can be achieved. Degree measurement; â€œResearch on the method and device for certifying the error rate of on-site speed measurement of radar speedometerâ€ studied the method of on-site speed measurement error falsification of radar speedometer, and developed a radar speedometer on-site speed error falsification device, which effectively ensured the radar speedometer on-site. The test data is accurate and reliable, providing an intuitive basis for analyzing the speed error.
Acceptance experts agree that key technical achievements such as the reappearance of large torques supported by static air bearings, automatic measurement of non-disturbance large-scale parameters, and high-precision wide-range dual-antenna Doppler radar speed measurement have been achieved in major national instrument special studies. International advanced level.
