25 Probe into the Bottom Measurement Property and Bottom Increment Testing Method of Vertical Tank

The property of the bottom measurement and the calculate method of bottom subside is simply introduced. As for the problems about measurement exiting in verification regulation of vertical metal tank capacity, a new putting-into-type liquid level meter method is presented, based on analysis of several resolvable methods. The method can measure exactly point deformation values of the tank bottom and improve the verification precision.
