A method and system for measuring a vertical densily profile of a fluid

Abstract From the Canadian patent

In a method and system for measuring a vertical density profile of a fluid in a fluid storage tank an array of open-ended pressure pipes extends downward into said fluid. The top end of each pressure pipe is connectable with a common pressurizing gas supply and the bottom end incorporates a fluid level sensor head. 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, - …
