Title:
METHOD OF MEASURING AMOUNT OF INSTANTANEOUS DISCHARGE OF POWDERY MATTER
Document Type and Number:
Japanese Patent JPH0735603
Kind Code:
A
Abstract:

PURPOSE: To provide a method of measuring amount of instantaneous discharge of powdery matter which allows the obtaining of hourly changes in the amount of instantaneous discharge of the powdery body smoothly and continuously regardless of the length of unit time for measuring the amount of an instantaneous discharge of a powdery matter to measure the amount of the instantaneous discharge of the powdery matter accurately.

CONSTITUTION: Water is supplied continuously to a continuous mixer 12 with a pump 12 while an instantaneous flow rate of the water is measured with a flowmeter 11 and changes in the number of revolutions of a motor la are applied through a motor controller 7 by an output signal based on the results of computation of an arithmetic controller 5 to control the discharge value of a powdery matter to be discharged from a supplier 1. The weight of a powdery storage device 2 is measured with a sensor 3 such as loadcell and a value thereof is outputted to the arithmetic controller 5 from a weight sensor converter 4 while the results of the computation are shown with an indicator 6 for the discharge value of the powdery matter. At the same time, a drive signal for the motor 1a is outputted to the motor controller 7 from the arithmetic controller 5 to chance the number of revolutions of the motor 1a through the motor controller 7 thereby controlling the discharge value of the powdery matter to be discharged from supplier 1.
