超声波流量计与转子式流速仪的比测

Test of ultrasonic flowmeter and rotor velocity calibration

水是经济社会发展的重要战略性资源之一。加强水资源的计量管理对水资源的科学管理有着重要意义。通过对天津市引滦隧洞管理处进口水文站的瑞士产RISONIC 2000型超声波流量计与流速仪测流2种计量手段的分析对比,验证RISONIC 2000型超声波流量计的流量测验精度,推广超声波流量计在输水明渠的测验经验。

The water is one of the important strategic resources in the economic and social development.It is of great significance to strengthen measurement management of water resource for the water resource scientific management.By the comparative analysis on RISONIC 2000 ultrasonic flowmeter made in Switzerland and current_meter discharge measurement in the project management authority of the water diversion tunnel from Luanhe River to Tianjin City,the precision of flowmeter measurement of RISONIC 2000 ultrasonic flowmeter was verified,the measurement experience of ultrasonic flowmeter in water distribution tunnel was popularized.
