Abstract
Measurement of an integrated weight of a particulate material being continuously fed to a powder treating system or the like by providing a powder delivery port in a lower portion of a pressurized powder feed container for supplying the particulate material to a blowing port of the treating system, connecting a pressurized powder replenishing container to an upper portion of the powder feed container for replenishing the power feed container with the particulate material under pressure, continuously feeding the particulate material along with part of a pressurized carrier gas introduced into the delivery port of the pressurized powder feed container, communicating the powder replenishing and feed containers with each other with suitable timing for replenishing the particulate material, sequentially measuring the weights of powder contents in the containers to measure the integrated weight of the particulate material fed through the delivery port during a time period of operation; batchwise combining the weight of each powder replenishment from the replenishing container to the feed container to obtain the total weight of powder replenishment, subtracting the sum of the weights of momentary powder contents of the containers from the total weight of powder replenishment when the measurement is made in concurrence with a replenishing operation, and subtracting the weight of momentary powder content of the pressurized powder feed container from the total weight of powder replenishment when measurement is made at a time point falling outside the timer period for a replenishing operation.
