1/8 Inch Water Flow Sensor YF-S401

• The YF-S401 Water flow sensor measures water flow accurately using a hall effect sensor and digital pulses.
• It has a flow rate of 0.3-6 litres per minute and outputs a pulse for every revolution of the pinwheel sensor, which is approximately 2.25 millilitres each.
• It is ideal for monitoring water flow through laser cutters or CNC machines for cooling.
• The hall effect sensor is sealed from the water pipe, making it a reliable and accurate option for measuring water flow in various applications.
• It can be used in water heaters, vending machines, automatic water dispensers, agriculture, food processing, coffee/tea makers, and water management systems.
• It is a small and lightweight device, making it easy to install and use.

The YF-S401 Water flow sensor is a small device comprising a plastic valve body, a water rotor, and a hall effect sensor. As water flows through the Water flow sensor, the internal rotator changes its speed in accordance with the rate of flow, and the hall effect sensor outputs a series of digital pulses. This allows the flow rate to be accurately measured using a microcontroller.

This Water flow sensor is ideal for use with laser cutters or CNC machines to monitor the flow of water through the laser tube or spindle for cooling. This Water Flow Sensor has a flow rate of 0.3-6 litres per minute and outputs a pulse for every revolution of the pinwheel sensor. These pulses are approximately 2.25 millilitres each and can be easily counted to calculate the water flow.

One of the key advantages of the YF-S401 Water flow sensor is that the hall effect sensor is sealed from the water pipe, ensuring it stays safe and dry. This makes it a reliable and accurate option for measuring water flow in various applications.
