PURPOSE:To make the adjustment of cement milk in a cement silo on board a ship accurate, by using load cells for measuring the weights of a material to be measured and a standard weight prototype, receiving the electric signals by a microcomputer, and performing computation. CONSTITUTION:A standard weight prototype 6 supports a standard weight 7, which is manufactured so as to have accurate weight of 1kg, in a tightly closed container 9 through a load cell 8 just as in a cement silo 2. The standard weight prototype 6 is arranged at the position of the center of gravity G2 in the cement silo 2. The electric signals, which are generated by the respective load cells 5 and 8 for the cement silo 2 and the standard weight prototype 6, are inputted to a controller C. Cement is continuously taken through a rotary feeder 10, which is provided at the lower end of the cement silo 2, into a mixing tank 11. Fresh water is supplied from a fresh water pipe 12. |
