PURPOSE:To enable a leaking position of fluid to be estimated in a piping by means of a relatively simple equipment at a low cost, by obtaining a gradient of pressure corresponding to each flow of the fluid in the sending end and receiving end of a transport pipe. CONSTITUTION:The increase in a feed flow is measured by a flow meter FX1 upstream from a fluid leadking position, while the decrease in an accepted flow is measured downstream thereof by a flow meter FX2. If fluid is caused to leak, sending and receiving pressures P1, P2 change into new sending and receiving pressures P1', P2' while a flow of the fluid changes, and the gradient of pressure also changes in the length direction of a pipe line. When a straight line C of the pressure gradient is derawn starting from the sending pressure P1' after the fluid leakage, and similarly a straight line D of the pressure gradient is drawn, starting from the receiving pressure P2' the intersection X between these straight lines signifies a leaking point. |
