The 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.
• SKU: GL-LINK-LEVEL
• Sensor Type: Submersible / throw-in liquid level sensor
• Output Signal: 4–20 mA
• Input Voltage: 24V DC
• Compatible Controller: Growlink batch tankLINK
• Ecosystem: Growlink LINKS
• Measurement: Continuous proportional liquid-depth reading across the tank depth
• Monitoring: Real-time batch tank level/volume monitoring
• Automated Refill: Supports automatic refill triggering through batch tankLINK
• Low-Level Threshold: Programmable through the batch tankLINK controller
• High/Low Alerts: Configurable thresholds with on-screen alerts and Growlink OS push notifications
• Data Logging: Up to 21,600 data points per sensor through batch tankLINK
• History: Graphical tank-level history available on the batch tankLINK LCD
• Connectivity: Wired directly to the batch tankLINK level-sensor input
• Remote Monitoring: Available through Growlink OS and Growlink app when batch tankLINK is connected to the Growlink HUB or Wi-Fi
• Calibration: Performed through the batch tankLINK's on-screen menu
• Application: Batch nutrient tank fill-level monitoring and automated refill control
• Installation: Throw-in/submersible installation directly in the nutrient tank
• Standalone Use: No — automated refill, alerts, logging, and Growlink OS integration require a batch tankLINK controller
• Sold Separately: Yes; batch tankLINK controller is not included
• Other Tank Parameters: batch tankLINK can simultaneously monitor EC, pH, temperature, and tank level using separate probes/sensors
Key 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.
