## Where each value comes from

This source states these in separate places, so each value is shown with the passage it comes from.

### Instrument type

> ANNEX VII MEASURING SYSTEMS FOR THE CONTINUOUS AND DYNAMIC MEASUREMENT OF QUANTITIES OF LIQUIDS OTHER THAN WATER (MI-005) The relevant essential requirements of Annex I, the specific requirements of this Annex and the conformity assessment procedures listed in this Annex, apply to measuring systems intended for the continuous and dynamic measurement of quantities (volumes or masses) of liquids other than water.

### Accuracy class

The source prints this value inside the passage below but does not name it there. The passage shows where it appears; what ties it to this record is the position on the page, not anything the passage says.

> 7. Putting into use Table 5 Accuracy Class | Types of Measuring system | 0,3 | Measuring systems on pipeline | 0,5 | All measuring systems if not differently stated elsewhere in this Table, in particular: — | fuel dispensers (not for liquefied gases), | — | measuring systems on road tankers for liquids of low viscosity (< 20 mPa.s) | — | measuring systems for (un)loading ships and rail and road tankers (2) | — | measuring systems for milk | — | measuring systems for refuelling aircraft | | 1,0 | Measuring systems for liquefied gases under pressure measured at a temperature equal to or above – 10 °C | Measuring systems normally in class 0,3 or 0,5 but used for liquids — | whose temperature is less than – 10 °C or greater than 50 °C | — | whose dynamic viscosity is higher than 1 000 mPa.s | — | whose maximum volumetric flowrate is not higher than 20 L/h | | 1,5 | Measuring systems for liquefied carbon dioxide | Measuring systems for liquefied gases under pressure measured at a temperature below – 10 °C (other than cryogenic liquids) | 2,5

### Maximum permissible error

> 2.1. For quantities equal to or greater than 2 litres the MPE on indications is: Table 2 | Accuracy Class | | 0,3 | 0,5 | 1,0 | 1,5 | 2,5 | Measuring systems (A) | 0,3 % | 0,5 % | 1,0 % | 1,5 % | 2,5 %
