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.
