The Water Flow Detector (Digital Trigger) is a high-reliability flow detection module engineered to provide instant digital ON/OFF feedback based on water movement within a pipeline. Unlike analog flow sensors, this detector delivers a clean digital trigger signal, making it ideal for PLC inputs, controllers, relays, alarms, and automation systems.
Designed for industrial and commercial environments, the module detects flow presence or absence rather than measuring volume, ensuring fast response, low latency, and dependable operation. The digital trigger activates when flow exceeds a predefined threshold, enabling pump protection, dry-run prevention, leakage detection, and system interlocking.
Built with industrial-grade components, the Water Flow Detector offers stable performance, low power consumption, and long service life, even in continuous-duty installations. It integrates seamlessly with PLC, SCADA, BMS, IoT controllers, Arduino, ESP32, and Raspberry Pi, making it a versatile solution for modern automation systems.
This detector is widely used in HVAC systems, water treatment plants, cooling circuits, industrial machinery, and smart building infrastructure where reliable flow detection is critical.
