A METHOD AND SYSTEM FOR MEASURING A VERTICAL DENSITY PROFILE OF A FLUID |
摘要 |
In a method and system for measuring a vertical density profile of a fluid (2) in a fluid storage tank (1) an array of open-ended pressure pipes (4) extends downward into said fluid. The top end of each pressure pipe is connectable with a common pressurizing gas supply (9) and the bottom end incorporates a fluid level sensor head (3). The following steps are carried out for each pipe: - connecting said pipe with the common gas supply, - conducting the pressurizing gas into said pipe thereby forcing the fluid downward into said fluid level sensor head, comprising a lower end part in which the fluid passes an outlet opening forming an abrupt transition between said lower end part and an open ended tube, - determining a level indicating signal from the passing fluid, - determining a pressure indicating signal from the pressure on the fluid, and - deriving from said level and pressure indicating signals information on the said vertical density profile. |
