5. آپريشن

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.
