SAIER SEN-HZ21TD G1/2 Nylon Water Flow Sensor | 1-20L/min Hall Flowmeter | NPN Pulse

For fluid monitoring systems requiring high strength and stability, the SAIER SEN-HZ21TD G1/2 nylon water flow sensor provides the perfect solution. The main body is constructed from industrial-grade nylon with glass fiber, ensuring a lightweight design while withstanding water pressure up to 1.75MPa and adapting to harsh environments. Powered by a precision Hall effect principle, it supports a wide flow monitoring range of 1-20 L/min and outputs a stable NPN transient pulse signal (F=10Q±10%). The sensor comes with standard G1/2 threads and a mounting bracket, allowing for flexible installation in any direction. The wiring terminal features a minimalist yellow, red, and black three-wire design (without a white wire) and offers multiple rated voltage versions including DC3V, DC5V, or DC24V, making it the ideal core component for fluid control in water treatment and automated equipment.
