Description:
The YF-G1 Water Flow Sensor DN25 G1 Water Pipe Flow Meter is a compact and practical water flow measurement sensor designed for monitoring and measuring water flow in pipelines. Featuring a durable plastic body, rotor assembly, magnetic rotor, and Hall-effect flow sensor, this module detects water movement and converts the rotating impeller movement into electrical pulse signals for a connected controller or monitoring system.
As water passes through the sensor, the internal rotor rotates according to the flow speed. The magnetic rotor interacts with the Hall sensor to generate corresponding pulse signals. A compatible controller can then process these pulses to determine the water flow rate. This makes the YF-G1 suitable for water flow monitoring, automatic control systems, Arduino projects, IoT applications, and liquid flow measurement systems.
The sensor features a 1-inch pipe connection and operates from a 5V to 24V DC power supply, making it suitable for a wide range of low-voltage electronic control systems. It offers an accuracy of approximately ±3% within the specified 1–60 L/min measurement range and provides a pulse output related to the measured flow rate.
The YF-G1 incorporates a stainless-steel bearing and embedded stainless-steel ball to improve rotor sensitivity and smooth operation. Its Hall sensing element is isolated from direct water contact and encapsulated with epoxy resin, helping provide protection against oxidation and environmental exposure.
With its compact design, easy installation, pulse-based output, and reliable flow detection, the YF-G1 Water Flow Sensor is a useful choice for water flow monitoring and automation applications where real-time flow information is required.

Frequently Asked Questions ( FAQs )
1. What is the YF-G1 Water Flow Sensor used for?
The YF-G1 Water Flow Sensor is used to detect and measure water flow through a compatible pipeline. It uses an internal rotor, magnetic component, and Hall-effect sensor to convert water movement into electrical pulse signals. A compatible controller or microcontroller can count these pulses and calculate the flow rate. It is commonly suitable for Arduino projects, IoT water monitoring, automation systems, water dispensing equipment, and DIY flow measurement applications.
2. What is the flow range of the YF-G1 water flow meter?
The YF-G1 is designed for a flow range of approximately 2–100 L/min, while the provided accuracy specification is ±3% for 1–60 L/min. Actual measurement performance can depend on installation conditions, water quality, pipe configuration, and system flow characteristics. Users should select the sensor based on their required flow range and ensure that the operating conditions remain within the specified limits.
3. How does the YF-G1 Water Flow Sensor detect water flow?
When water passes through the sensor, it causes the internal impeller/rotor assembly to rotate. A magnetic rotor attached to the assembly interacts with the Hall-effect sensor, which generates electrical pulse signals according to the flow. The connected controller can count these pulses and use the specified pulse relationship to determine the approximate water flow rate. This allows the sensor to provide digital flow information for monitoring and automation systems.
4. Can the YF-G1 Water Flow Sensor be used with Arduino and IoT projects?
Yes, the YF-G1 is suitable for compatible Arduino, microcontroller, and IoT projects where water flow needs to be monitored or measured. The sensor provides a pulse output that can be read by a suitable digital input on a controller. Developers can process the pulse signal to estimate water flow and create applications such as water usage monitoring, automatic pump control, smart irrigation, and water management systems.
5. What should I check before installing the YF-G1 DN25 G1 Flow Sensor?
Before installation, check the pipe size, water pressure, flow range, operating voltage, flow direction, and electrical connections. The sensor has a 1-inch/DN25 G1 connection and should be installed securely with suitable fittings. Keep the pressure within the specified limit and supply the module with DC 5–24V. Also ensure that the pipeline is clean and free from debris that could interfere with the internal rotor. Proper installation helps provide more reliable flow measurement and longer sensor service life.
