  1. We provide default K value for each different hall flow sensor.

  2. You can calibrate by the following formula:

  • Default K Value*DT/RT=New K Value

  • DT: Display total volume in one minute(L)

  • RT: real total volume in one minute(L)

  3. For example, the default K value is 4, the real total volume is 10L, the display total volume is 8L, 

      then the new K value is 4*8/10=3.2

  4. Repeat the calibration twice, and the accuracy will reach the best.
