Multi-jet dry dial brass body water meter 20 manufacturer
Use condition:
Cold water:0.1~30℃
Hot water:0.1~90℃
Work pressure:≤1MPa.
Water meter flow error curve and pressure loss curve:
Allowable error of indication and error curve:
The maximum allowable error of low zone is as follows:
The maximum allowable error of discharge volume between minimum flow (Q1) and boundary flow (Q2) (excluding Q2) is ± 5%.
Maximum allowable error in high range:
The maximum allowable error of discharge volume is ± 2% based on the flow between boundary flow (Q2) (including Q2) and overload flow (Q4).
