Omfang

3.1B.1 Scope This standard covers level measurement of liquid hydrocarbons in stationary, aboveground, atmospheric storage tanks using automatic tank gauges (ATGs). The standard discusses automatic tank gauging in general, calibration of ATGs for custody transfer or inventory control, and the requirements for data collection, transmission, and receiving. Appendices discuss the operation and installation of the most commonly used ATG equipment and of less common, electronic ATGs. This standard does not cover the following: a. Hydrocarbons having a Reid vapor pressure above 15 pounds per square inch absolute (100 kPa). b. Measurement of weight or mass with ATG equipment. c. Measurement of level in underground tanks or in pressurized tanks storing liquid hydrocarbons. d. Conversion of tank level to liquid volume. e. Measurement of temperature, sampling, density, and sediment and water (S & W), which are discussed in Chapters 7-10 of the Manual of Petroleum Measurement Standards. Safety and material compatibility precautions should be taken when using ATG equipment. Manufacturers' recommendations on the use and installation of the equipment should be followed. Users should comply with all applicable codes and regulations, API standards, and the National Electric Code.
