Division 7.1

The relative MPE of the flow sensor, expressed in %, for accuracy classes:

• Class 1: $E_f=\left(1+{\mathrm{0,01\; q}}_p∕q\right)$ , but not more than 5 %,

• Class 2: $E_f=\left(2+{\mathrm{0,02\; q}}_p∕q\right)$ , but not more than 5 %,

• Class 3: $E_f=\left(3+{\mathrm{0,05\; q}}_p∕q\right)$ , but not more than 5 %,

where the error E_f relates the indicated value to the true value of the relationship between flow sensor output signal and the mass or the volume.
