The ZOOX FlowDian is a sophisticated standalone flow meter designed for saltwater reef aquariums, providing precise, real-time monitoring of actual water flow rate and temperature within your plumbing system. This essential tool empowers hobbyists to accurately assess the performance of their return pumps, reactors, and other equipment, ensuring optimal water movement and stability throughout their aquatic environment.

Key features of the FlowDian include a clear, local display for both flow rate and temperature, complemented by a customizable monitoring range and an integrated audible alarm (buzzer) for immediate alerts to any deviations. It offers broad compatibility, accommodating both 1-inch and 3/4-inch plumbing sizes with an included compact reducer. Furthermore, the FlowDian is available in two distinct models—one displaying units in US Gallons and Fahrenheit, and another for Liters and Celsius—and supports USART communication for seamless integration into advanced aquarium automation systems.

This flow meter is an invaluable asset for reef aquarists who demand meticulous control and oversight of their system's vital parameters. It is particularly beneficial for diagnosing pump efficiency, optimizing the flow rates for various reactors, or ensuring consistent thermal conditions crucial for sensitive corals and livestock. Its standalone functionality combined with advanced communication capabilities makes it a versatile and powerful instrument for both hands-on management and integrated smart aquarium setups.
