Abstract
Slurry consisting of water and solid matters are charged into a plurality of vessels by means of a low-pressure slurry pump, and is discharged into a transfer pipe by fluid pressure generated by a high-pressure driving liquid pump. A float member is positioned at the border of the slurry and the driving liquid in each vessel. Any failure taking place in the apparatus is displaced or informed on the basis of the period of time taken by each float member moving between the upper and lower limit positions or the number of movements.
