Add wireless flow monitoring to any existing Hunter HC Flow Meter installation or replace a damaged transmitter without buying the full kit. The Hunter W-HC-FLOW-TR is the field-side component of the Wireless HC Flow Meter pair. It mounts directly onto or near the HC Flow Meter in the valve box or underground and communicates wirelessly with the W-HC-FLOW-R receiver installed at the Hydrawise-enabled controller.
Do You Need the Transmitter or the Receiver?
- W-HC-FLOW-TR (this product) — Transmitter. Mounts at or near the flow meter in the ground or valve box. Battery-operated (3 × AA). If the unit in the field is damaged or missing, this is the part you need.
- W-HC-FLOW-R — Receiver. Mounts at or inside the controller. Powered by 24 VAC from the host controller. If your controller-side unit needs replacing, order the receiver instead.
- WHCFLOW kit — Includes both. Best value if you need both (saves $75.03 vs buying separately).
