Monitor water flow accurately and conveniently with rotameter flow meters from The Water Company. Our range includes variable-area flow meters for domestic, commercial and industrial water treatment applications, with measuring ranges suited to different system flow rates.

A rotameter uses a visible float inside a graduated measuring tube to indicate the flow rate as liquid passes through the meter. This simple, easy-to-read design makes rotameters useful for monitoring water flow through filtration systems, reverse osmosis plants and other water treatment installations.

Benefits of Rotameter flow meters:

Easy visual monitoring: The float and graduated scale provide a direct indication of flow.

Simple operation: Standard mechanical rotameters do not require electrical power to display flow.

Multiple flow ranges: Select a meter that suits the expected flow rate of your system.

Practical installation options: Inline and panel-mount designs suit different equipment layouts.

Useful system monitoring: Flow readings can help operators identify changes in system performance.

How to choose the correct Rotameter:

Before ordering, confirm the expected flow rate, required measuring units, connection size and type, installation orientation, operating pressure and temperature. For accurate readings, select a meter whose measuring range matches the normal operating flow of the system.

Rotameters must be installed in the orientation specified by the manufacturer, typically vertically with the flow entering from below. Always check the individual product specifications, as pressure ratings, temperature limits, accuracy and connection types vary between models.
