Cabinet of Ministers Regulations No. 669 in Riga august 22, 2006 (pr. No 43) provisions on metrological requirements for liquids (except water) measuring systems Issued in accordance with the law "about the measurement unity of" the second subparagraph of article 6 and the law "on conformity assessment" 7. the first paragraph of article 1. determine the metrological requirements and the conformity assessment procedures of liquids (except water) measuring systems, before the liquids (except water) are placed in the measuring of the internal market, as well as the cast. 2. the meaning of these provisions: 2.1 capacity meter-measuring tool for the fluid volume for continuous measuring, storing in memory and indication that conditions at the measuring flow through the measurement transducer in a closed, completely filled in the pipeline;
2.2.-the volume meter enumeration part that receives the output signals from the measurement transducer and possibly also from papildmērlīdzekļ and displays the measurement results;
2.3. the papildmērlīdzekl-measuring tool that is attached to certain specific liquid computing size measuring, to make corrections, modifications or adjustments and modifications;
2.4. conversion device-computing part that, taking into account the characteristics of the liquid (for example, temperature, density), which measured with papildmēr or enter the measurement memory: 2.4.1. volume of the liquid measured automatically converts the volume, as well as to examine the mass;
2.4.2. the mass of the liquid measured automatically converts the volume at metering conditions, as well as the capacity to examine;
2.5.-examine specific conditions to which the measured fluid volume results in the conversion of liquid volume is displayed;
2.6. measuring system-a system that includes the same volume meter and all the necessary equipment to ensure correct measurement or measurement activities;
2.7. fuel filling apparatus-measuring system, which is designed for the filling of fuel in vehicles, small boats and small aircraft;
2.8. self-service equipment-equipment, which enables the customer to use a measuring system for liquids of the same needs;
2.9. self-service device-specific device that is part of a self-service. Self-service device supports one or more of the activities of the respective measuring system of self-service equipment;
2.10. minimum mērlielum (MMQ) – the smallest quantity of liquid for which the measurement is metrologically acceptable for the measuring system;
2.11. direct reading-volume or by mass readings for measuring and where the meter is physically incapable of measuring. Using the conversion device, direct display can transform the size;
2.12. discontinuing/not interruptible measuring system-measuring system is considered as interruptible/non interruptible when the liquid flow can/cannot stop the easy and fast;
2.13. mērdiapazon flow-range between the minimum flowrate (Qmin) and maximum flowrate (Qmax). 3. The essential requirements for liquids (except water) measuring systems set in the Act, regulations of metrological requirements measuring instruments. Particular requirements for liquids (except water) measuring systems set in the annex to these provisions. 4. Liquid (except water) of a measuring system shall comply with the requirements of these rules and regulations in the Act on the metrological requirements measuring instruments. 5. The manufacturer may choose conformity assessment procedures of modules B + F or B + D or H1 or g. modules set in the Act, regulations of metrological requirements measuring instruments. 6. Liquid (except water) systems for which type-approval was issued to this provision to the date of entry into force of the market and allowed to put liquids (except water) systems, which made the first verification, allowed to pass until they use the type approval expiration date, but if it is not set, the-by 2016 of 30 October. 7. The entry into force of the provisions by 30 October 2006. Informative reference to European Union Directive provisions included in the law arising from the European Parliament and of the Council of 31 March 2004, Directive 2004/22/EC on measuring instruments. Prime Minister a. Halloween economic Minister a. Štokenberg annex a Cabinet of 22 august 2006 the Regulation No 669 special metrological requirements 1. Manufacturer indicates measuring systems under certain operating conditions, in accordance with this annex 2., 3., 4. and 5. 2. Flow mērdiapazon into each of the components of the measuring system shall be within the limits of mērdiapazon, in particular the capacity measure range, flow relationship corresponds to table 1 of this Annex establishes the conditions. table 1 maximum and minimum flow for different measuring systems for Measuring the Fluid nature of the minimum ratio of Qmax/Qmin refuelling apparatus not liquefied gas 10:1 5:1 of liquefied gas measuring system Cryogenic liquids: 1 Measuring 5 on the pipelines and the bilge of the measuring system for filling all the liquids for use in applied general systems of all liquids 4:1, 3. the characteristics of the liquid to be measured determines the name of the liquid or the relevant characteristics (e.g., temperature range, the pressure range density range viscosity range). 4. Energy source represents the nominal value of the AC as well as limit values for direct current. 5. examine the converted size is determined. 6. The maximum permissible error (MPE) value depending on the quantity of the liquid to be measured for various classes of accuracy defined by this annex, the table 2 and 3. table 2 CPC values measured quantities of the liquid, which is equal to and greater than two litres of accuracy class 0.3 0.5 1.0 1.5 2.5 0.3% Measuring (A) 1.0% 0.5% 1.5% 2.5% capacity measures (B) 0.3% 0.2 0.6% 1.0%% 1.5% table 3 MPE measurable quantities of liquid, which is less than two litres the MPE V the measured volume 0.1 l 2 < Quadruple the value shown in the table If the volume to be measured is 0.1 litre 0.1 l
