Description

The Rotameter 5–35 L/min panel mount square flow meter is a compact variable-area flow meter designed for measuring and monitoring the flow rate of water through a piping system. The visible float moves within the measuring tube as water passes through the meter, allowing the operator to read the approximate flow rate directly from the graduated scale.

Its square panel-mount design provides a convenient solution for integrating flow monitoring into equipment panels and water-treatment systems. The acrylic measuring body and easy-to-read scale provide a clear visual indication of flow, while the mechanical design requires no electrical power for basic flow measurement.

Suitable for water filtration, purification, reverse osmosis and other water-treatment applications, the Rotameter provides a simple and practical method of monitoring water flow.

How a Rotameter works:

A Rotameter is a variable-area flow meter. As water flows through the measuring tube, it causes the internal float to move in response to the flow rate. The position of the float corresponds to the water flow rate shown on the graduated scale.

As the flow rate increases, the float moves higher within the measuring tube. The operator can then read the approximate flow rate directly from the graduated scale.

This provides a simple visual indication of water flow without requiring electrical power.

Installation:

The Rotameter should be installed in accordance with the manufacturer’s installation requirements and with the panel and measuring tube positioned correctly to allow the float to move freely and provide a clear flow-rate reading.

The connected pipework should be properly supported to prevent excessive mechanical stress on the meter. Flush the pipework before installation to remove debris that could interfere with the float or measuring tube.

Ensure that the system flow falls within the Rotameter’s 5–35 L/min measuring range and that the operating pressure and temperature remain within the specified limits.

Important:

• Check that the required system flow falls within the 5–35 L/min measuring range.
• The equivalent flow range is approximately 0.3–2.1 m³/h.
• The equivalent flow range is approximately 300–2,100 L/h.
• Confirm that the 1″ female threaded connection is compatible with the existing piping system.
• Ensure that the system operating pressure does not exceed 100 PSI (approximately 6.9 bar).
• Ensure that the operating temperature remains between 5°C and 50°C.
• Install the Rotameter in the correct orientation to allow the float to move freely.
• Ensure the panel installation provides adequate support for the flow meter.
• Flush the pipework before installation to remove debris.
• Support connected pipework to prevent excessive mechanical stress on the Rotameter.
