<P>PROBLEM TO BE SOLVED: To prevent propagation of bacteria or the like, to enable measurement of an accurate leakage amount, and to reduce burdens of cleaning on an operator. <P>SOLUTION: A dam type leakage amount measuring device used when measuring the leakage amount of a dam includes: a water channel 13 for measurement, which is provided with a drain port 32 on a bottom part, and whose cross section in a lateral direction is roughly U shaped; a dam 15 for measurement provided so as to dam flowing water vertically to the longitudinal direction of the water channel for measurement, on a downstream side end part of the water channel for measurement; water level measuring means 70 installed on the upstream side of the dam for measurement so as to measure a water head level of leakage inside the water channel for measurement; a data processing part having leakage amount conversion means for converting the leakage amount from a water level measured value measured by the water level measuring means; sterilization means 50 for sterilizing a notched part of the dam for measurement for fixed time; drainage means 30 having a drain outlet opening mechanism and a drain outlet closing mechanism provided on a bottom part of the water channel for measurement; a clock part for measuring the time; and a control part for controlling respective operations of the water level measuring means, the sterilization means and the drainage means on the basis of the time measured by the clock part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
