NOTE
Maximum allowable error:
1. The maximum allowable error of high zone flow rate (Q2≤Q≤Q 4) is
± 2% when the water temperature range is 0.1 ℃ ~ 30 ℃. When the
water temperature is higher than 30 ℃, the maximum allowable error
of ± 3%.
2.The low zone flow rate (Q1≤Q ≤Q2) is ± 5% , regardless of the
water temperature range.
