Description

The AQUA Rotameter 1–7 L/min round profile flow meter is a compact variable-area flow meter designed for measuring and monitoring the flow rate of water through a piping system. As water passes through the measuring tube, the internal float moves according to the flow rate, allowing the operator to read the approximate flow directly from the graduated scale.

Its compact round-profile design provides a simple and convenient solution for visual water-flow monitoring. The rotameter operates mechanically and does not require electrical power for basic flow measurement, making it suitable for a range of water filtration, purification and treatment applications.

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.

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

Installation:

The rotameter should be installed in accordance with the manufacturer’s installation requirements, with the measuring tube positioned in the correct orientation to allow proper float movement and 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.

Important:

• Check that the required system flow falls within the 1–7 L/min measuring range.
• Confirm the connection size and connection type before installation.
• Ensure that the system operating pressure does not exceed the manufacturer’s specified maximum working pressure.
• Ensure that the operating temperature remains within the manufacturer’s specified temperature range.
• Install the rotameter in the correct orientation to allow the float to move freely.
• Flush the pipework before installation to remove debris that could interfere with the float or measuring tube.
