Abstract

PURPOSE: To maintain securely the self-suctioning characteristic of the water pumping device by diluting remaining sample water with a pure water such as the water from the water supply automatically.
CONSTITUTION: When the water pump 9 is stopped, a valve 8 opens at an appropriate interval to introduce air into a conduit on the suction side, so that the sample water on this side drops its level. After several seconds elapses, the valve 8 closes whereas another valve 22 opens so as to operate a diluting water pouring pump 24 to pour the diluting water for a time period T. After that, the valve 22 closes and waits for a restart of the water pump 9. The water pump 9 remains in an inter- locked condition not to restart until the valve 22 is closed.
