The CoralVue Hydros 1 Flow Sensor HDRS-FM100 is an essential piece of equipment for any modern saltwater or freshwater aquarium system utilizing the Hydros control platform. This easy-to-install flow meter seamlessly communicates the real-time water flow rate to your Hydros app, providing crucial monitoring capabilities. It is designed for versatile application, perfect for keeping an eye on reactor feed lines and the performance of your return pumps. Boasting a robust flow range of 50-1500 gallons per hour, this sensor ensures accurate readings for a wide array of setups. It comes equipped with Schedule 80 PVC unions featuring 1-inch BSPP pipe threads for secure integration into your plumbing, and an ample 8-foot wire length for flexible placement. Installation requires a Hydros Control unit with an available Sense Port, basic plumbing knowledge, and standard pipe thread tape and PVC adhesive, which are not included. This flow sensor is ideally suited for aquarists who value precision, automation, and peace of mind in their reef-keeping endeavors. By integrating with the Hydros app, collected flow data can be used to create custom rules, such as triggering an alert or shutting off equipment connected to a Hydros Control XP8, Power 4 WiFi power strip, or Smart Plug if flow rates deviate from desired thresholds. This proactive monitoring helps ensure vital aquarium equipment operates correctly, safeguarding your aquatic environment.
