Abstract: In installations where both pressure regulation and measurement facilities are installed, measurement errors can occur as a result of poor pressure control. In any installation, the proper design, installation, and operation of pressure regulators is important for good pressure control and safe operations. Where measurement is installed also, these areas become more critical in order to obtain not only good control, but also accurate measurement. This paper is intended to describe those areas where regulator problems can affect measurement accuracies. It will alsoaddress those areas of design, installation, and operation that are important to obtaining good pressure control along with accurate measurement. Poor regulator performance will affect accurate volume measurement in the following areas - calculation of displacement, orifice and turbine meter volume inaccuracies in the orifice meter flow coefficient errors in fixed factor measurement, and errors in turbine meter index volumes. Each of these items are discussed below.
