Overview

The Industrial Brass Hall Effect Water Flow Sensor is engineered for high-precision monitoring in liquid circulation systems. Constructed with a heavy-duty, corrosion-resistant brass body and a standardized G1" threaded interface, it reliably supports a flow range of 2–50 L/min. By leveraging advanced Hall Effect technology, the internal magnetic rotor converts fluid movement into consistent pulse signals in real-time. Designed for durability, this sensor ensures long-term operational stability across a wide temperature spectrum (−20°C to 100°C) and is optimized for use with clean water and non-corrosive media.

Feature

High-Strength Brass Construction: The premium brass valve body is rated for operating pressures up to 1.75 MPa, providing superior structural integrity and corrosion resistance for demanding industrial environments.

Precision Hall-Effect Sensing: Utilizes the linear relationship between pulse frequency and flow velocity to deliver high-accuracy data output and stable signal transmission.

Broad Flow Versatility: Covering a dynamic range of 2–50 L/min, this sensor is highly adaptable, catering to both low-flow precision monitoring and high-volume water supply systems.

Excellent Thermal & Electrical Stability: Features industry-leading insulation resistance (>100 MΩ), ensuring robust anti-interference performance and safe operation during continuous, long-term duty cycles.

Standardized G1" Integration: The precision-machined G1" threads ensure a leak-proof, high-compatibility connection, significantly reducing installation time and maintenance complexity.
