PURPOSE: To improve processing capability, without inputting additional materials, by forming a plurality of combination of weights of materials in measuring tanks having different capacities, and judging the weights in comparison with the objective values.
CONSTITUTION: Based on the materials to be measured in measuring tanks and small-capacity measuring tanks, measured signals are generated by respective load detectors 5 and 9. The measured signal from each detector 5 is supplied to a combination operating part 12. Based on a combination signal from a combination generator 14, the measured signals are sequentially combined. The combined measured signals are compared with the preset values of allowable upper and lower limits of weight setting device 18 and 20 by a judging part 16. The signal, which is closest to the allowable lower limit weight is stored 22. The measured signal from the detector 9 is added 23 to each combined measuring signal. The output is compared with the allowable upper and lower limit values by a judging part 24. The combined signal, which is closest to the lower limit signal is stored 26. When all the combinations are finished, the materials to be measured are discharged in correspondence with the proper combination state.
