Commercial and Industrial Flow Meters LZM and LZS series


Ro Agua manufactures various flow meters for our water treatment projects. Most of our variable area flow meters (also known as rotary flow meters) have dual scales of GPM and LPM and can be installed online or on a panel. For your convenience, our flow meters range from 0.1 gpm to 250 gpm.

The flow meters used to monitor system flow are panel-mounted or pipeline-mounted and easy to install.
