How to Calibrate K Value of US211M and US211M lite?
We provide default K value for each different hall flow sensor.
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.
