This sensor is designed for measuring the flow rate of liquids within a range of 1 to 30 liters per minute.
2. Informații de siguranță
- Ensure all power is disconnected before installation or maintenance to prevent electrical shock.
- Nu depășiți volumul specificattage and current ratings to avoid damage to the sensor.
- Verify that all connections are secure and leak-free before operating the system.
- This sensor is designed for water and non-corrosive liquids. Do not use with flammable or corrosive substances.
- Protect the sensor from freezing temperatures, which can cause damage.
3. Produs terminatview
The Gavigain G1/2" Copper Hall Effect Water Flow Sensor is a robust device used to detect and measure liquid flow. It features G1/2" male threaded connections for easy integration into plumbing systems. The sensor operates on the Hall effect principle, where an internal impeller rotates with the flow of liquid, generating a series of electrical pulses. The frequency of these pulses is directly proportional to the flow rate.

5. Configurare și instalare
Follow these steps for proper installation of the water flow sensor:
- Pregătiți sistemul: Ensure the water supply is turned off and the system is depressurized before beginning installation.
- Identificați direcția fluxului: Locate the arrow marked on the sensor body. This arrow indicates the direction of liquid flow. Install the sensor so that the liquid flows in the direction of the arrow.
- Conexiune mecanică: Connect the G1/2" male threads of the sensor into your plumbing system. Use appropriate thread sealant (e.g., PTFE tape) to ensure a watertight seal. Hand-tighten first, then use a wrench for a snug fit, but do not overtighten to avoid damaging the threads or sensor body.
- Cablaj electric: The sensor typically has three wires:
- Fir roșu: Connect to positive (+) power supply (e.g., +5V to +24V DC).
- Sârmă neagră: Connect to negative (-) or ground.
- Sârmă galbenă: Pulse signal output. Connect this to your microcontroller or display unit's input pin.
- Testare pentru scurgeri: Slowly turn on the water supply and carefully check all connections for any leaks. Tighten connections as necessary.
- Verificați semnalul: Power on your control system and verify that the sensor is outputting a pulse signal when water flows through it.
6. Instrucțiuni de utilizare
Once installed, the water flow sensor operates by converting the mechanical rotation of an internal impeller into electrical pulses. The frequency of these pulses is directly proportional to the volume of liquid passing through the sensor.
- Măsurarea debitului: Your control system (e.g., microcontroller, PLC) will count the pulses generated by the sensor over a specific time period.
- Calibrare: Each sensor may have a slightly different pulse-to-liter ratio (K-factor). It is recommended to calibrate your system by flowing a known volume of water through the sensor and adjusting your software's calculation accordingly. A common K-factor for G1/2" sensors is approximately 450 pulses per liter, but this can vary.
- Aplicatii: This sensor is suitable for various applications including water heaters, vending machines, water dispensers, flow control systems, and industrial equipment requiring liquid flow monitoring.
7. Întreținere
The Gavigain water flow sensor is designed for durability, but proper maintenance can extend its lifespan and ensure accurate readings.
- Inspecție regulată: Periodically inspect the sensor and connections for any signs of wear, corrosion, or leaks.
- Preveniți înghețarea: In environments where temperatures may drop below freezing, ensure the sensor and connected pipes are drained or adequately insulated to prevent ice formation, which can cause severe damage.
- curatenie: If the sensor's performance degrades, it may be due to debris accumulation inside the impeller chamber. Disconnect power and water supply, carefully remove the sensor, and flush it with clean water. Avoid using harsh chemicals or abrasive tools that could damage the internal components.
- Conexiuni electrice: Ensure electrical connections remain clean, dry, and secure.
