The YF-B1-S Stainless Steel Liquid Flow Sensor (1/2 inch) is a precision-engineered flow measurement device for accurate measuring of liquid flow in pipes. Featuring a robust stainless-steel body and durable internal components, it ensures high corrosion resistance, long lifespan, and stable performance in harsh environments.
This sensor operates on a wide voltage range of 3.5V to 24V DC, generating a pulse signal proportional to the flow rate. With a measurement range of 1–25 L/min (±3%), it’s ideal for applications like water dispensers, industrial control systems, and smart water monitoring. Its G1/2 thread design ensures easy installation, and the compact 66 mm body allows it to fit into tight spaces.
The sensor provides a high-level output signal (>DC 4.5 V) and low-level output (<DC 0.5 V) at 5 V DC input, making it compatible with most microcontrollers, PLCs, and IoT systems. Designed for temperatures up to 80 °C, it maintains accuracy and reliability even under demanding operating conditions.
