Abstract

PURPOSE: To quickly and accurately detect leak in a closed pipe line by providing liquid circulation loop which is connected to the closed pipe line via lead pipe and by attaching pump and flow meter at one end and pressure control value which responds to pressure variation in the pipe line and flow meter at the other end.
