Product description:
Variable area flowmete with glass metering cone flowmeter is consists of a vertical glass metering cone from bottom  to top and a movable float along with the flow rate. There is the functional relationship between the flow rate and the section area, so the float height position is the flow indicating value. It suitable for measuring the  single~phase nonfluctuatiing fluid(liquid or gas).
Shuanghuan participated in designing and drawing up the standard of domestic variable area flowmeter with glass metering cone at the earliest time.


Quality standard:
The quality standard is : JB/T9255-1999, and according to ISO9001:2008 to control the quality.Each product has to inspect contain leak tightness test, pressure test, etc. We ask our supplier provide test report of raw material, each electrical element has to detect, so every finished product has factory test report and data record.We introduced special technique and equipment from KROHNE in Germany, 228 sets fabrication and gauging equipment to calibrate the flowmeter,  and also NCM,milling machine,grinding machine from Japan to ensure the accuracy of the spare part. Self-production proportion of spare part up to 90%
