Product FAQ

What are the advantages of 304 stainless steel in residential water flow sensors? +
The 304 stainless steel valve body provides superior corrosion and oxidation resistance, ensuring the sensor remains rust-free even during prolonged exposure to domestic tap water. Its high structural integrity offers excellent pressure tolerance (up to 1.2 MPa) and long-term stability, preventing heavy metal contamination and ensuring the safety of the household water supply.
What type of signal does the residential water flow sensor output? +
This sensor outputs a precise NPN pulse signal (Square Wave). The pulse frequency is directly proportional to the real-time flow velocity. This standardized output allows for seamless integration with smart home controllers, PLC systems, or digital flow meters to achieve accurate water consumption monitoring and leak detection.
Is this flow sensor suitable for daily residential water applications? +
Absolutely. The CUCIR residential series is specifically engineered for household environments. It features a low-pressure drop design that does not interfere with normal tap water pressure. It is ideal for purified water systems, water heaters, and smart irrigation, providing stable and reliable measurements across a wide temperature range (up to 100°C).
