Installation and Usage Instructions:
Before use, ensure a filter is installed at the sensor's water inlet to prevent particles and debris from entering.
The sensor must be installed indoors or within equipment. Avoid prolonged exposure to harsh conditions like humidity, high temperatures, or outdoor environments. Install in a stable environment to prevent vibration and shaking, which could affect measurement accuracy.
Keep magnetic materials or objects generating a magnetic field away from the sensor to avoid altering its characteristics.
Do not disassemble the water flow sensor, as unauthorized disassembly voids the warranty.
