Configuració i instal·lació

1. Instal·lació mecànica

The flow sensor features G1 (0.5 inch) male threaded connections on both ends. Ensure the flow direction arrow on the sensor body aligns with the intended water flow in your system. Apply appropriate thread sealant (e.g., PTFE tape) to prevent leaks. Tighten connections securely but do not overtighten.

Instruccions de funcionament

Principi de funcionament

The DIGITEN G1 Water Flow Sensor uses a Hall effect sensor to detect the rotation of an internal turbine. As water flows through the sensor, it spins a turbine, and a magnet attached to the turbine generates a series of electrical pulses. The frequency of these pulses is directly proportional to the flow rate of the water.

Flow Rate Calculation

The output signal is a square wave. The flow rate (Q in L/min) can be calculated from the measured frequency (F in Hz) using the following formula:

F = 4.8 * Q (L/min)

Therefore, to find the flow rate:

Q (L/min) = F / 4.8

The sensor provides approximately 450 pulses per liter of water. The accuracy is ±2%.

Manteniment

  • Inspecció periòdica: Periodically check for any signs of leaks at the connections or damage to the sensor body and wiring.
  • Neteja: If the sensor's accuracy degrades, it may be due to debris accumulation inside the turbine. Disconnect power and water supply, then carefully remove the sensor for inspection and cleaning. Use a soft brush and clean water to remove any obstructions.
  • Emmagatzematge: If storing the sensor for an extended period, ensure it is clean, dry, and kept within the specified storage temperature and humidity ranges (-25°C to +80°C, 25%-95% RH).
