1/2 Inch Brass Water Flow Sensor SEN-HZ21WI
The SEN-HZ21WI water flow sensor is a device that is used to measure the flow rate of water. It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device. The sensor is commonly used in applications such as irrigation systems, water treatment plants, and industrial process control.
It can easily measure water (liquid) flow in your application using this 1/2" Brass water flow sensor. This is a good quality flow sensor with a brass body and can be used for industrial and commercial applications. This half-inch water flow sensor is used extensively in various types of vending machines.
Working of a Flow Sensor:
The water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls, its speed changes with different rates of flow. And the hall-effect sensor outputs the corresponding pulse signal. This water flow sensor is connected in line with the liquid whose flow rate has to be measured. There is a simple rotating wheel with a magnet and when the liquid flows the wheel is rotated and a hall effect sensor measures how many times the wheel is rotated and accordingly gives pulses. By counting the number of pulses you can easily calculate the flow rate as well as the amount of liquid dispensed.
Note:
- When magnetic material is close to the sensor, its characteristics may vary.
- In order to avoid particle debris, the sensor must be installed after a filter.
- The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
Applications:
- Widely used in water industrial fields
- Thermostatic water heaters
- Water purifiers
- Water dispensers
- Smart card equipment
- Coffee machines
- Electric hot water heater
- Gas water heater
- Instrument meter

1. What are the uses of a Water flow sensor?
- Water flow Sensors are commonly used in HVAC systems, medical devices, chemical plants, and sewage treatment plants. The Flow sensors can detect leaks, blockages, pipe ruptures, and changes in liquid concentration due to contamination and dirt.
2. How do fluid flow sensors work?
- As the liquid flows through the rotor, the rotor rolls, and its speed changes at different flow rates. And the hall sensor will output the corresponding pulse signal. A flow sensor is a component that measures the flow of a fluid, such as gas or liquid. Flow sensors use both mechanical and electrical subsystems to measure changes in the physical properties of a fluid and calculate its flow rate. Measurement of these physical properties depends on the physical properties of the liquid.
