Water Flow Sensor 3/8 in Quick Connect for Coffee Machines and Water Dispensers
This Water Flow Sensor with a 3/8" PE Quick Connect delivers precise flow measurement for coffee machines and water dispensers, supporting 0.3–10 L/min with 1260 pulses per liter and a stable, reliable signal.
Its sealed housing prevents leakage and wear, extending service life in busy kitchens and offices. Built for wide voltage compatibility (3.5–24 V DC), it suits a broad range of devices and projects. Made from RoHS-compliant POM, it targets safe, eco-friendly operation with a medium temperature range of -20 to 80°C and a water pressure tolerance up to 0.8 MPa.
The sensor outputs a pulse signal that feeds easily into microcontrollers or counters: high level > 4.7 V at 5 V input and low level < 0.5 V. Key specs include inner diameter 9.7 mm, water-only medium (no impurities), and insulation resistance > 100 MΩ. Model YF-S301, origin Mainland China, with certifications including CE, Dot, EAC, EPA, FCC, GMP, RoHS, TGA, UL, KC, PSE, and weee. No PCB included and no battery required for operation.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
Benefits & Tips
- Use in coffee machines or water dispensers to monitor actual water flow and detect flow anomalies early.
- Integrate with a microcontroller or data logger to track usage patterns and optimize beverage dispensing routines.
- Apply in DIY water projects where accurate flow measurement improves control and efficiency.
