the absolute value of the MPE given in Table 2 or Table 3,
the absolute value of the MPE for the minimum measured quantity (Emin).
Condition 1
Emin shall fulfil the condition: Emin ≥ 2 R, where R is the smallest scale interval of the indication device.
Condition 2
Emin is given by the formula: , where:
MMQ is the minimum measured quantity,
A is the numerical value specified in line A of Table 2.
In the case of a converted indication the MPEs are as in line A of Table 2.
MPEs on converted indications due to a conversion device are equal to ± (A — B), A and B being the values specified in Table 2.
Parts of conversion devices that can be tested separately
MPEs on quantities of liquid indications applicable to calculation, positive or negative, are equal to one-tenth of the MPEs as defined in line A of Table 2.
Associated measuring instruments shall have an accuracy at least as good as the values in Table 4:
MPE on Measurements | Accuracy classes of the measuring system | ||||

0,3 | 0,5 | 1,0 | 1,5 | 2,5 | |
Temperature | ± 0,3 °C | ± 0,5 °C | ± 1,0 °C | ||
Pressure | Less than 1 MPa: ± 50 kPa From 1 to 4 MPa: ± 5 % Over 4 MPa: ± 200 kPa | ||||
Density | ± 1 kg/m3 | ± 2 kg/m3 | ± 5 kg/m3 |
These values apply to the indication of the characteristic quantities of the liquid displayed by the conversion device.
The MPE for the calculation of each characteristic quantity of the liquid, positive or negative, is equal to two fifths of the value fixed in (b).
