HUB & CONNECTIVITY – Requires YoLink Hub; Ethernet or 2.4 GHz Wi-Fi for flexible installs; works with Alexa, IFTTT, and Home Assistant.

ABOUT PIPE SIZE & FLOW – Sized by nominal pipe size (NPS) for thread compatibility. The ultrasonic measurement tube is intentionally smaller to meet accuracy standards and stabilize readings; the assembly is engineered for typical household/light-commercial service flows.

INSTALLATION REQUIREMENTS — Install the device in a suitable location according to the installation environment and operating conditions. Avoid exposure to excessive moisture, flooding, standing water, condensation, extreme temperatures, and other harsh conditions unless the device is specifically rated for such environments. Use proper protection, insulation, or enclosures when required. Improper installation or prolonged exposure to unsuitable conditions may damage internal components, affect measurement accuracy, or impact valve performance.
