Water Flow Sensor (Sea) DN32 Flowmeter 1.25” 1-120L/min 3.5-24V
- This DN32 water flow sensor consists of a plastic valve 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. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispensers or coffee machines.

How to Use Water Flow Sensor (Sea) DN32 Flowmeter 1.25” 1-120L/min
Install the sensor inline on a horizontal 32 mm (1.25”) water pipe using compatible fittings. Connect the three wires—power (3.5–24 VDC), ground, and pulse output—to your controller or microcontroller digital input. As water flows, count pulses per second and apply the calibration factor (provided in the datasheet) to calculate real-time flow rate.

Frequently Asked Questions
How do I calculate flow rate from the pulse output?
Count the number of pulses generated per second by the hall-effect sensor. Multiply the pulse frequency by the sensor’s pulses-per-liter constant (found in the datasheet) to obtain the flow rate in L/min.
What is the maximum water pressure this sensor can handle?
This DN32 flowmeter is rated for water pressures up to 2.0 MPa. Ensure your system pressure does not exceed this limit to maintain accuracy and prevent damage.
Can I use this sensor with hot water?
The ABS plastic body and metal rotor are suitable for typical water temperatures found in dispensers and coffee machines. Avoid exposure to steam or temperatures beyond standard machine operating ranges to prevent material degradation.
