2,Flow point and its definition:
a,Overload flow Q4---water meter can meet the maximum permissible error requirement in a short time, then returned nominal operating conditions can maintain metrological characteristics of the maximum flow; it is "1.25 times the nominal flow" Q3.
b,Nominal flow Q3---maximum flow under nominal operating conditions, this flow meet the maximum permissible error requirements.
Tip: This flow is not optimal flow of water meter, but the maximum flow.
c,Transitional flow Q2---between the “nominal flow”Q3 and minimum flow Q1,it divided flow range into "high zone" and "low zone" two zones, each zone has specific maximum permissible error. Transitional flow Q2 is 1.6 times the minimum flow Q1.
d,Minimum flow Q1---the minimum flow value that Water meter can display, it also meets the maximum permissible error . It has a fixed proportional relationship with "nominal flow" Q3.
3,Removable Woltman water meter working conditions:
a.Working temperature:lower than 40°C (hot water meter lower than 90°C)
b.Working pressure:≤1.0 MPa
c.Pressure loss:≤0.03MPa
4,Removable Woltman water meter maximum permissible error:
From transitional flow Q2 to overload flow Q4 is ±2% (hot water meter is±3%).
From minimum flow Q1 to transitional flow Q2 (not includeQ2) is ±5% for both cold and hot water meter
5,Features of removable woltman water meter:
This kind meter is removable, you can simply open the cover, remove the meter core for repair or replacement without removing the meter from the pipe, counter is fully enclosed. Can replac nine kinds of caliber water meter without cutting off water, three kinds of meter core, wide versatility. Low pressure loss, long work life.
