Glass Tube Rotameter is primarily a Variable Area Flow Meter. It is used for measuring instantaneous flow rate of liquids and gases. It is one of the oldest way of measuring the flow in use till date.
Glass Tube Rotameter consists of a conical flow tube. It has a linearly increasing cross section from bottom to top. It consists of a float as the primary element to indicate flow rate.
The float rises due to an increase in the flow velocity. As a result, the position of the float at different flow is then marked, calibrated. Finally it is then machined to form a scale on the eternal body of the Glass Tube Rotameter to device a perfect display.
Scharf Automation's Glass Tube Rotameters are available in Flanged / Screwed / TC End connection and are installed in the pipeline facing vertically upward.
Furthermore, our Glass Tube Rotameters are fitted with toughened glass for an added strength.
It is most noteworthy that for higher accuracy flow measuring applications and for remote monitoring of flow via an analog 4-20mA output, our Turbine Flow Meter is recommended
Since Glass Tube Rotameters have an accuracy of 2% whereas Turbine Flow Meter
have a much accuracy of 0.5%.
Besides this, Turbine Flow Meter
have direct interfacing options with PLC/SCADA based Automation.
