Legal Metrology Act, 2014 (Act No. 9 of 2014)RegulationsLegal Metrology Regulations, 2017Part XI : Measuring instruments and containers used for prescribed purposes111. Liquid meter systems for predetermined quantities |
| (1) | Except as otherwise provided in this regulation, the liquid meter system for predetermined quantities must conform to provisions of regulation 108(1), (2), (3), (4) and (5). |
| (2) | A liquid meter system for predetermined quantities must be designed to determine the quantity of a liquid to be delivered and to repeat such determination indefinitely, without the quantity requiring to be reset: Provided that provision may be made for the predetermination by an operator of the system of various quantities to be delivered. |
| (3) |
| (a) | A liquid meter system for predetermined quantities must have the full details of its measuring capacity marked on the meter or on the housing if the meter is enclosed or on a metal plate permanently affixed thereto. |
| (b) | Where provision is made in a system for the predetermination of various quantities to be delivered, such predetermination must be clearly defined on the liquid meter system for predetermined quantities and the denomination of such quantities must be clearly marked on the system. |
| (4) | A liquid meter system for predetermined quantities not provided with an eliminator referred to in regulation 108(2)(b), must not operate when the supply of liquid is reduced to the minimum level this is to prevent air from entering the meter. |
| (5) |
| (a) | The type of liquid which is normally measured by a liquid meter system for predetermined quantities must be used for testing the system and the liquid must be provided by the user of the system. |
| (b) | After the liquid meter system for predetermined quantities and any delivery hose or pipe attached there to have been thoroughly flushed, the meter must be tested for accuracy and constancy of delivery by allowing the liquid to flow from the system directly into an appropriate measurement standard of volume that comply with the requirements in Part III of these Regulations: Provided that, where the capacity of the system or some other factor precludes the method of direct comparison with a measure of volume, the net mass of the liquid delivered must be determined by means of a weighing instrument that comply with the requirements in Part III of these Regulations and such net mass must be converted to the measure of volume on the basis of the density of the liquid. |
| (c) | Where a liquid meter system for predetermined quantities provides for the delivery of various predetermined quantities, each such quantity or as many such quantities as the market surveillance inspector or verification officer considers necessary, must be tested. |
| (d) | Tests of a liquid meter system for predetermined quantities must be repeated a sufficient number of times as the market surveillance inspector or verification officer considers necessary to provide reliable data. |
| (6) | Permissible errors allowed on the meter of a liquid meter system for predetermined quantities, in excess or in deficiency, in accordance with Table 18 in regulation 107. |
