Description
The 5–35 L/min Panel-Mount Rotameter is a variable-area flow meter designed for monitoring water flow in reverse osmosis, filtration and water treatment systems.
Its panel-mount square design makes it particularly suitable for installation on equipment control panels where the operator needs a clear visual indication of water flow.
The easy-to-read graduated scale allows the flow rate to be monitored while the system is operating.
Features:
- Flow range: 5–35 L/min.
- Equivalent flow: 300–2,100 L/h.
- Equivalent flow: 0.3–2.1 m³/h.
- Panel-mount design.
- Square profile.
- Acrylic body.
- Easy-to-read graduated scale.
- Stainless-steel 304 float.
- Stainless-steel 304 guide.
- Polypropylene connections.
- EPDM component.
- 1-inch female inlet and outlet.
- Maximum pressure: 100 PSI.
- Operating temperature: 5–50°C.
- Accuracy: ±5%.
- Suitable for water-flow measurement.
Applications:
- Domestic reverse osmosis systems.
- Commercial RO systems.
- Water purification systems.
- Water filtration systems.
- Water treatment equipment.
- RO control panels.
- Filtration control panels.
- Water treatment skids.
- Pump and filtration systems.
- Small commercial water treatment plants.
- Process water systems.
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.
