Water meter is mainly composed of housing, impeller metering mechanism and instructions, C for eight pointer readings, E for pointer readings word wheel combined, E table indicating device has a full hydraulic and fluid sealing, sealing the indicating device with special liquid encapsulation can keep for a long time, water meter with a clear reading, high sensitivity, advanced structure, accurate measurement, long service life
Flow point and its definition
Overload flow (Q4) -- The upper limit of the flow rate used by the water meter. In the overload flow, the water meter is not allowed to be used for a long time and can only be used for a short time without damage. No more than an hour a day.
Common Flow rate (Q3) -- The flow rate that the water meter allows to work for a long time.
Boundary flow (Q2) -- The flow rate between the usual flow rate and the minimum flow rate when the meter error limit changes.
Minimum flow (Q1) -- The lower flow rate used by the water meter.
Indicates the value error limit
The range from minimum flow to boundary flow (excluding boundary flow) is ±5%.
