The WXZJ-JSG20A Series Metal Tube Rotameter is used for flow measurement of liquids, gases, or steam in closed pipelines. It is widely applied in process control, particularly suitable for the control and measurement of small to medium flow rates.

The WBXY-JSG20A Series Metal Tube Rotameter consists of a tapered tube, float, indicator, and converter. Fluid flows into the tapered tube, causing the float to rise. When the buoyant force M balances the gravitational force G, the displacement of the float is transmitted to the indicator via a magnet for local flow indication. Alternatively, the converter transforms this into corresponding electrical signals (two-wire system 4-20mA, three-wire system 0-10mA, four-wire system 4-20mA or 0-20mA). It can be matched with electric unit combination instruments or connected to a computer network for remote display, recording, regulation, integration, and control of flow.
