Liquid weighing device

The invention relates to a liquid weighing device used for weighing liquid of a target weight continuously or in a single process. A weighing hopper of the liquid weighing device is connected with a weighing rack through a weighing sensor. The lower end of the weighing hopper is connected with a welded pipe through a rubber hose. A ventilation pipe is arranged in the side face of the welded pipe.According to the invention, measurement errors are reduced to be as low as 0.5%; the measurement efficiency is improved and the measurement time of a single measurement process can be shorten to be 2-5 seconds. 本发明涉及种液体称量装置，该装置用来连续或单次测量某目标重量的液体。该液体称量装置的称量斗通过称重传感器与称量支架连接，且称量斗的下端通过橡胶软管连接焊管，焊管侧面设有通气管。本发明减小了测量误差，测量误差可以减小到0.5％；提高了测量效率，单次测量时间可以缩短2-5秒。
