Such liquid It can be divided into two categories. Liquefied natural gas (LNG) and liquefied petroleum gas (LPG). In order to make shipping safe and economical, a large number of these liquids Transported on ship design and construction requires a special technique. In custody transfer for the purpose of determining the amount of the tank cargo ship must achieve a high level of accuracy. This section and the same series Other provisions of the standards are internal measurements aboard tanks, this method can be deduced from the tank calibration tables. For internal measurements, typically using a liquid correction method, physical measurements, optical measurement and three-dimensional photographic measurements. Liquid correction method does not For large spherical tank near atmospheric pressure canned light hydrocarbons frozen, canned quiet because when the liquid is higher than a plane, the applied correction fluid Hydraulic may exceed the design pressure. From considering the accuracy of the method, if the correction results from other methods suspicious, you can use three-dimensional photographic Measurement as arbitration. Three-dimensional photographic measurements include pictures of the tank wall and interior photos of the target analysis. This section clearly defines the mapping camera to take pictures with a universal perspective and analyze the plotter approach. Refrigerated light hydrocarbon fluids calibration of spherical tanks on board Part 1. stereoscopic measurement1 ScopeSection 1.1 provides for the internal spherical tanks of liquefied gas vehicles on the three-dimensional photographic measurement procedures. 1.2 In addition to the actual measurement step, this section describes the computer program to edit the calibration table.2 Normative referencesThe following documents contain provisions which, through reference GB/T 24958 in this section constitute provisions of this section.

When the volume of the member so that the effective volume of the tank is increased, stayed the wood called "Wood stay positive", when the volume of member Displaces the liquid volume decreases the effective volume of the tank, the spent wood called "negative stay wood." 3.6 Equatorial equator Spherical shell maximum horizontal circumference. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 24958.1-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 24958.1-2010_English as soon as possible, and keep you informed of the progress.
