1 Cranes, valves, scrolling, pistons and other locking devices or conversion devices shall be so executed and closed so that the accuracy of the measurement cannot be damaged.
2 Stripes, overruns, peilglasses and other insti tuation and reading devices for the purpose of determining or designating a boundary of the space for measuring and the size of such a border area shall not, in the measurement of measurement, be of any kind meaning in relation to the maximum permissible errors.
Liquid mirrors at the height of the individual partial stripes can be set up and read off parallaxis. If necessary, the discontinuous fuel gauge shall be provided by means of such devices.
The shape and layout of the discontinuous fuel meters and the power supply lines shall ensure the full supply of the measured quantity and the complete delivery of the measured quantity. The viewing glasses shall be fitted to that end if necessary.
The parts which serve to fill and empty are immutable and have been carried out and installed in such a way that the measurements are reliable and unambiguous and, in the case of cropping, no differences of any meaning in relation to the maximum permissible Errors occur.
Conversion devices shall be constructed and installed in such a way that the liquid may only follow that direction when measuring or switching, and where appropriate measurement is ensured.
The discontinuous fuel gauges in which the measuring space at the top and bottom edges is bounded by a locking device shall be equipped with a special device, which shall ensure that the supply line can be opened first after full operation of the vehicle. fill of the metering space and first can be closed after full emptying.
If the underside of the metering area is bounded by a shut-off device, the soil and, where appropriate, the drain pipe shall at least have the following gradient:
a. Continuously Prepared Discontinuous Fuel Meters: in the ratio of 1:10;
b. In the case of non-solid discontinuous fuel meters: in the ratio of 1:5.
Retreadable devices shall be such that use that results in a measurement error, which is significantly less than the maximum permissible error, is not possible or can easily be determined.
The discontinuous fuel meters are so arranged that the correct operation of built-in discontinuous fuel meters is not impaired and they can be easily examined.
In the case of the discontinuous fuel meters intended for the measurement of different fuels in varying mixing ratios, these fuels may be mixed with one another only to a small extent when changing the mixing ratio.
1 The discontinuous fuel meters shall be arranged so as to ensure that no air or gas can be carried forward. Where necessary, the meters shall be provided with a discharge or discharge device by which a proper disposal of non-contained, carried-out air or gases is possible.
2 The ventilation or discharge devices shall be so arranged that the fault resulting from the air or gas carried out is significantly lower than the maximum permissible errors.
1 In respect of the first conformity assessment, the maximum permissible errors in plus or minus for the quantities given below shall be as follows:
Quantity in litres
Maximum allows

2 After putting into service the maximum permissible errors shall be the double of the values determined in paragraph 1.
1 By way of derogation from the provisions of Article 101 amounts in the first conformity assessment of discontinuous fuel meters which are designed exclusively to deliver a quantity of liquid after insertion of one or more cash or tokens and where the measurement by a human action cannot be exercised, the maximum permissible errors in the quantities given below:

On each discontinuous fuel meter, either directly or on a plate attached to the measuring instrument, it shall be specified:
the name and address of the person who has produced the discontinuous fuel meter or his factory mark;
b. The year in which the discontinuous fuel meter is manufactured and the factory number;
(c) the number of the declaration of authorisation concerned;
d. Any other indication, which is deemed necessary by the designated authority to determine the composition or operation of the discontinuous fuel meter, as indicated in the declaration of authorisation.
This arrangement shall enter into force from 1 February 2007.
This scheme is based on the Articles 8 , 11 and 14, first and third paragraphs, of the Decision measuring instruments and market participants .
This arrangement is cited as: Arrangement measuring reservoirs, liquid altimeters and discontinuous fuel meters.
This arrangement will be set out in the Official Journal.
