ઓપરેશનનો સિદ્ધાંત
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%.

જાળવણી
- નિયમિત તપાસ: Periodically check for any signs of leaks at the connections or damage to the sensor body and wiring.
- સફાઈ: 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.
- સંગ્રહ: 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).
