Description
The 8–40 m³/h Rotameter is a variable-area flow meter designed to measure water flow through pipelines and water treatment systems.
The clear graduated scale provides a simple visual indication of the flow rate while the system is operating. This makes the Rotameter useful for monitoring and checking water flow in filtration, reverse osmosis and other water treatment applications.
The plastic tube construction provides a lightweight and corrosion-resistant solution for water flow measurement.

How a Rotameter works:
A Rotameter is a variable-area flow meter. As water flows upward through the tapered tube, it causes the internal float to rise. The position of the float corresponds to the flow rate shown on the graduated scale.
This provides a simple visual indication of the water flow rate without requiring electrical power.
Important:
Always check the flow range, connection size and operating pressure before purchasing to ensure the Rotameter is suitable for your application.
