{"product_id":"growlink-level-sensor","title":"Growlink Level Sensor","description":"\u003cp\u003eThe Growlink Batch Tank Level Sensor (GL-LINK-LEVEL) is a submersible, throw-in liquid-level sensor designed specifically for the Growlink batch tankLINK controller. Its continuous 4–20 mA output provides proportional tank-depth readings rather than a simple high\/low indication, allowing the controller to monitor nutrient volume in real time, trigger automated refills at a programmed level, and generate high\/low level alerts through Growlink OS.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: GL-LINK-LEVEL\u003cbr\u003e\n• Sensor Type: Submersible \/ throw-in liquid level sensor\u003cbr\u003e\n• Output Signal: 4–20 mA\u003cbr\u003e\n• Input Voltage: 24V DC\u003cbr\u003e\n• Compatible Controller: Growlink batch tankLINK\u003cbr\u003e\n• Ecosystem: Growlink LINKS\u003cbr\u003e\n• Measurement: Continuous proportional liquid-depth reading across the tank depth\u003cbr\u003e\n• Monitoring: Real-time batch tank level\/volume monitoring\u003cbr\u003e\n• Automated Refill: Supports automatic refill triggering through batch tankLINK\u003cbr\u003e\n• Low-Level Threshold: Programmable through the batch tankLINK controller\u003cbr\u003e\n• High\/Low Alerts: Configurable thresholds with on-screen alerts and Growlink OS push notifications\u003cbr\u003e\n• Data Logging: Up to 21,600 data points per sensor through batch tankLINK\u003cbr\u003e\n• History: Graphical tank-level history available on the batch tankLINK LCD\u003cbr\u003e\n• Connectivity: Wired directly to the batch tankLINK level-sensor input\u003cbr\u003e\n• Remote Monitoring: Available through Growlink OS and Growlink app when batch tankLINK is connected to the Growlink HUB or Wi-Fi\u003cbr\u003e\n• Calibration: Performed through the batch tankLINK's on-screen menu\u003cbr\u003e\n• Application: Batch nutrient tank fill-level monitoring and automated refill control\u003cbr\u003e\n• Installation: Throw-in\/submersible installation directly in the nutrient tank\u003cbr\u003e\n• Standalone Use: No — automated refill, alerts, logging, and Growlink OS integration require a batch tankLINK controller\u003cbr\u003e\n• Sold Separately: Yes; batch tankLINK controller is not included\u003cbr\u003e\n• Other Tank Parameters: batch tankLINK can simultaneously monitor EC, pH, temperature, and tank level using separate probes\/sensors\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: Unlike a basic float switch that only detects a predetermined level, the GL-LINK-LEVEL provides continuous 4–20 mA level information, enabling precise refill thresholds, tank-volume trend logging, and both high- and low-level alerts through the Growlink system.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610195329060,"sku":"GL-LINK-LEVEL","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/level-sensor-gl-link-level.webp?v=1791317774","url":"https:\/\/www.growitdepot.com\/products\/growlink-level-sensor","provider":"Grow It Depot","version":"1.0","type":"link"}
