SYSTEM FOR CORRECTING LIQUID DISCHARGING AMOUNT OF PNEUMATIC PRESSURE DISPENSER

摘要

The liquid discharge amount correction system of the pneumatic dispenser according to the present invention comprises: a dispenser driving unit for driving a pneumatic dispenser equipped with a syringe containing liquid based on a user's operation; a pressure detection unit configured to detect a discharge pressure of the liquid when the pneumatic dispenser is driven; a heating unit for heating the liquid contained in the syringe to a predetermined temperature; a temperature detection unit detecting a temperature of the heated liquid; a liquid amount calculator configured to calculate the amount of remaining liquid in the syringe based on the detected discharge pressure, the heating temperature of the liquid, and the discharge time of the liquid; a volume calculation unit for calculating a residual volume of the calculated residual liquid amount; And when the calculated residual volume is reduced than the preset reference volume, it is possible to correct the ejection pressure or the ejection time based on the reduced residual volume or to compensate the ejection pressure and the ejection time at the same time, and to automatically compensate the vacuum pressure inside the syringe It may include; a discharge compensator.
