5. Pouvwa sou: Once all connections are secure, apply power within the specified voltage ranje (DC 5-18V).

5. Operasyon

The DIGITEN G2 flow sensor operates by generating a series of electrical pulses, with the frequency of these pulses being directly proportional to the rate of water flow. This pulse signal can be read by a microcontroller (e.g., Arduino) or other compatible electronic devices to calculate the flow rate.

Understanding the Output Signal:

The sensor outputs a square wave pulse signal. The number of pulses per liter (K-value) is crucial for accurate flow calculation. While the exact K-value can vary slightly based on installation and specific conditions, it is typically determined through calibration. For this model, users have reported a K-value of approximately 0.2 pulses per liter, meaning 12 pulses per liter (as per user feedback, 12 pulses/L for 2 inch). It is recommended to perform your own calibration for critical applications.

6. Antretyen

The DIGITEN G2 Water Flow Hall Sensor is designed for low maintenance. However, adhering to the following guidelines can prolong its lifespan and ensure continued accuracy:

• Enspeksyon regilye: Periodically check for any signs of leakage around the connections or physical damage to the sensor body.
• Lapwòpte: While the sensor is designed for water, ensure the water flowing through it is relatively clean and free of large particles that could obstruct the impeller or cause wear.
• Kondisyon anviwònman: Asire w ke anviwònman operasyon an rete nan limit tanperati ak imidite espesifye yo.
• Evite konjelasyon: In cold environments, ensure the sensor and connected pipes do not freeze, as this can cause irreversible damage.

NAN. Depanaj

If you encounter issues with your DIGITEN G2 Water Flow Hall Sensor, consider the following troubleshooting steps:

• Pa gen Siyal Sòti:
  • Verify that the sensor is correctly wired (Red to VCC, Black to GND, Yellow to Signal).
  • Tcheke ekipman pou pouvwa a voltage to ensure it is within the DC 5-18V range.
  • Ensure there is actual water flow through the sensor.
• Lekti ki pa kòrèk:
  • Confirm the sensor is installed with the correct flow direction.
