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.

Description

1/8 Inch Water Flow Sensor YF-S401

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.

FAQ

1. How does a water flow sensor work?

The water flow sensor is made up of a plastic valve through which water can flow. A water rotor and a hall effect sensor are used to detect and measure water flow. When water flows through the valve, it causes the rotor to rotate. The motor's speed can be changed as a result of this.

2. What is the use of flow sensor?

Flow sensors are devices that measure the rate at which blood or oxygen flows through a vessel. Implantable flow sensors are commonly incorporated into a flexible cuff that is fitted around the vessel whose flow rate is to be measured.

3. What is a water flow sensor?

The water flow sensor is essentially a small turbine with a series of digital pulses as its output signal. The pulse frequency is proportional to the flow rate of the liquid through the sensor. That digital signal, whose frequency is in the range between 0Hz and 100Hz, can be read directly through one of the digital input/output pins of a microcontroller.
