MPE
The MPE, positive or negative, on volumes delivered at flowrates between the transitional flowrate (Q_(2)) (included) and the overload flowrate (Q_(4)) is: 2 % for water having a temperature ≤ 30 °C, 3 % for water having a temperature > 30 °C. The meter shall not exploit the MPE or systematically favour any party. The MPE, positive or negative, on volumes delivered at flowrates between the minimum flowrate (Q_(1)) and the transitional flowrate (Q_(2)) (excluded) is 5 % for water having any temperature. The meter shall not exploit the MPE or systematically favour any party.
