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. Konfigurazioa eta instalazioa
Follow these steps for proper installation of the water flow sensor:
- Prestatu sistema: Ensure the water supply is turned off and the system is depressurized before beginning installation.
- Identifikatu fluxuaren norabidea: 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.
- Konexio mekanikoa: 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.
- Kableatu elektrikoa: The sensor typically has three wires:
- Hari gorria: Connect to positive (+) power supply (e.g., +5V to +24V DC).
- Hari beltza: Connect to negative (-) or ground.
- Hari horia: Pulse signal output. Connect this to your microcontroller or display unit's input pin.
- Ihesak egiteko proba: Slowly turn on the water supply and carefully check all connections for any leaks. Tighten connections as necessary.
- Egiaztatu seinalea: Power on your control system and verify that the sensor is outputting a pulse signal when water flows through it.
6. Funtzionamendu-argibideak
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.
- Emaria neurtzea: Your control system (e.g., microcontroller, PLC) will count the pulses generated by the sensor over a specific time period.
- Kalibrazioa: 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.
- Aplikazioak: 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. Mantentzea
The Gavigain water flow sensor is designed for durability, but proper maintenance can extend its lifespan and ensure accurate readings.
- Ohiko ikuskapena: Periodically inspect the sensor and connections for any signs of wear, corrosion, or leaks.
- Izoztea saihestu: 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.
- Garbiketa: 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.
- Konexio elektrikoak: Ensure electrical connections remain clean, dry, and secure.
