Tomahawk

Itron water modules are compatible with all sizes of Tomahawk registers and RG3 meter models. 

The RG3 Tomahawk register is programmable for encoder or pulser. Select encoder configurations based on the model of the connected endpoint. Only the left-most seven dials are reported and the endpoint consumption value increments by one for every ten meter pulses.

A check valve is needed with RG3 Tomahawk registers for all Water Pulser endpoints to prevent Reverse Flow from causing an ERT/Meter display mismatch.

The following list describes the water modules with which these registers are compatible.
