3. Working Principle of Glass Tube Rotameter
The MT-F200RT operates on the principle of a variable-area flow meter. As the process fluid passes through the tapered glass tube, the float rises or falls in response to the flow rate. The height of the float is directly proportional to the volumetric flow rate and can be read visually against a calibrated scale on the tube.
Key benefits of this working principle include:
-
Direct visual flow indication without external power
-
High precision measurement with ±2% full-scale accuracy
-
Minimal maintenance due to simple mechanical design
-
Compatible with a wide variety of liquids and gases
This makes the MT-F200RT ideal for processes where continuous flow monitoring is critical.
