1¡¢Flow bound

a¡¢Maximum flow (Qmax)-top limit flow for the water meter . during the maxi-mum floe, the water can be used only for a short time . b¡¢Nominal flow (Qn)-the flow for a long time . c¡¢Transitional flow (Qt)- the flow for the water meter to be corrected for error. d¡¢Minmum flow (Qmin)-lower limited flow for the water meter . e¡¢Start flow (Qs)=the flow for the water meter to bengin the continuous indication . At this the water meter does not count the error of indicated value .

2¡¢Error curve

a¡¢The lower zone fron including the minimum (Qmin) to excluding the transitional flow (Qt)£º¡À5% b¡¢The upper zone fron including the transitional flow (Qt) to including the maximun flow (Qmax)£º¡À2%
