Water Hall Flow Sensor G1/2
This flow sensor is a reliable and efficient way to monitor the movement of liquid through a pipe system. Designed with a magnetic hall effect sensor and a spinning pinwheel, it detects the flow of water or other fluids and converts that movement into electrical pulses that can be interpreted by a data acquisition system. The sensor is safely sealed to protect the electronics from water exposure, making it a dependable choice for both indoor and outdoor applications.
Whether you're tracking water usage, automating a fluid control system, or collecting data for analysis, this sensor offers a seamless and straightforward installation. It connects easily to a wide range of data loggers and monitoring systems, making it a great option for both DIY users and professionals. With its durability and compatibility, it's a valuable addition to any project that requires accurate and consistent flow measurement.
Features:
- Measure flow from 1 to 30 Liters per minute
- Sealed integrated magnetic hall effect sensor outputs an electrical pulse with every revolution
