HM 9. Guidelines for selection and installation of meters on road/rail petroleum loading gantries

Overview:

This document provides guidance on the specification, design, and installation of measurement systems installed in road and rail loading gantries, operating on unheated white oil products, but the principles can be applied to the design of loading gantries for other products with the application of different performance criteria. The document excludes heated oils, heavier hydrocarbon products, liquefied petroleum gas (LPG) (both pressurised and chilled) and cryogenic products such as liquefied natural gas (LNG).

This document covers the gantry measurement system only; it does not cover the design of a complete loading system or the specific requirements for safe operation, particularly in respect of electrical and static electricity or the prevention of spillage.
