4. Working Principle of Glass Tube Rotameter MT-F210RT
The Glass Tube Rotameter MT-F210RT operates based on the variable area principle, a proven mechanical measurement method widely used in flow instrumentation.
-
The instrument contains a tapered glass tube, wider at the top and narrower at the bottom.
-
A float is placed inside the tube and moves freely according to the force of fluid flow.
-
As fluid enters from the bottom, the float rises until the upward pressure created by the fluid balances with the weight of the float.
-
The float position corresponds directly to the flow rate.
Because the float rises higher with increased flow, the reading scale printed alongside the tube indicates the exact flow value without requiring any external sensing or calibration device.
This operating principle offers several benefits:
-
Physically intuitive readings
-
No external power requirement
-
Minimal pressure drop
-
High reliability and repeatability
Optional flow control valves (inlet or outlet) enhance system control, enabling users to finely adjust flow rates directly at the rotameter.
5. Typical Applications of Glass Tube Rotameter MT-F210RT
The Glass Tube Rotameter MT-F210RT is well-suited for applications that require stable, low-to-medium flow measurement, especially where installation space is limited.
