Device processed, controller open timer and carry out timing；
Controller calculates the difference of the instant quality and dry powder fire-engine steadily halt when institute's mass metering that currently claim in real time,
Then effective spraying rate that division arithmetic obtains current powder fire monitor is carried out with time set the surveyed time, and passes through display device reality
When show.
Further, the quality that each independent weighing platform is surveyed is the sum of 4 mass sensor measurements.
Further, when on total weighing platform, every piece of independent weighing platform is used for the effect of measuring for dry powder fire-engine parking
In the quality of the platform, the numerical value that each independent weighing platform measures is added up into the current instant quality of dry powder fire-engine.
Compared with the background art, the invention has the advantages that:
1) when dry powder fire-engine powder fire monitor sprays, powder fire monitor is ejected to the quality and effective discharge time phase of dry powder in real time
In conjunction with being calculated current effective spraying rate, and pass through curve real-time display.
2) the configuration of the present invention is simple avoids repeatedly weighing back and forth, and is influenced by human factor smaller, substantially increases
Detection efficiency.The important device of dry powder fire-engine or other dry powder spraying systems detection effective spraying rate of powder fire monitor can be become.
