摘要： PROBLEM TO BE SOLVED: To solve a problem wherein 80-180 minutes or more of inspection time is required per one tank container in a conventional technique, and wherein a time of stopping business in a gasoline station until finishing the inspection of a plurality of underground tanks is required to be shortened at an early time, as a reason for solving early the problem, since a simple method realized early of about 40 minutes of inspection time is required in its initial stage, even when either of water or air exists in the periphery of a storage tank buried underground.
SOLUTION: The water continuously intrudes into an underside of an oil liquid stored in the tank container, as a slow water flow, when the water continuously intrudes from a leakage hole by depressurization. This method of the present invention uses a leaked water flow detector having a function capable of detecting the intrusion moving and the water flow of the slow water. The water flow detector is provided in a short period, in case of a simple method, and is advanced successively to high performance one capable of shortening further the inspection time, by complicating a little accompanying mechanical structure or the like.
