Abstract

PURPOSE: To perform a detection for the water leak, by measuring the flow rate regarding the branch point and the joint point of the flow system having plural flow paths and then carrying out an operation with a consideration given to the water sending time and under the conditions of an equal value between the flow-in amount and the flow-out amount.
CONSTITUTION: The flow-rate measurement points M1, M2, M3 and M4 and the flow rate measuring devices 4, 5, 6 and 7 are provided along with the flow paths 1, 2 and 3 having the branch point A. An operation applying the Kirchhoff's low is carried out via the water leak detector 8 possessing the electronic computer and for the points A and B plus a consideration given to the water sending time and under the conditions of an equal value between the flow-in amount and the flow-out amount. And then a decision is given to whether the result of opration exceeds the set allowance amount or not, thus performing a detection for the water leak.
