Hydrawise sells two types of flow meters: a 1" (25 mm) and a 3/4" (20 mm).
Flow meters have a dedicated connector on the side of the unit. For flow meters that have a diameter of 1.25" (32 mm) or greater, you can use three wires. However, only two wires are required to connect the flow meter to the controller.
Details on configuration are available in our downloadable guide.
