Abstract
PURPOSE: To simply, accurately and exactly measure the leaked water amount per unit time from the difference between the space volume in a container directly after completion of water supply and the space volume in the container after predetermined time.
CONSTITUTION: Intermediate valves 2, 3 are provided, for example at every 100m or predetermined interval of a buried tube 1. There is provided a ground joint valve 4 such as faucet or the like at suitable intermediate position between the valves 2 and 3. The valve 4 is connected via a water feed hose to a leaded water measuring unit 5. By opening or closing the valves 2, 3, the leakage and the leaked amount of water are measured by the unit 5 by utilizing the internal pressure difference of the tube changing upon leakage of the water.
