ICWM Series Water Meters

Advanced Single-Jet Technology Water Meters

Rain Bird ICWM Series Water Meters

Rain Bird’s ICWM Series Water Meters are engineered to measure water use with sustained accuracy at both high and low flow rates. ICWM uses a single measuring element that can record flows that are 10 times lower than other types of water meters, such as displacement, traditional turbine and multi-jet.


Incoming water rotates a suspended impeller with an embedded magnet on top. The offset impeller allows the meter to pass sand and other particulates through the measuring chamber with no effect. A low friction pivot bearing supports the floating impeller at low flow rates while a thrust bearing provides the support at high flow rates. The patented "dual bearing" design provides unparalleled accuracy and durability at both high and low flows.


ICWM Water Meters are available in 7 different models, suitable for a wide range of uses, including residential, commercial and industrial applications.
