A device of liquid flow measurement has a drip infusion formed on a top of the device. The drip infusion has a drawing pressure pass. The drawing pressure pass is communicated with the drip infusion and has a pressure sensing module. A pressure communicating pipe is placed under the drip infusion and is extended into the drawing pressure pass. The present invention may be serial connected in a small flow during measurement. The present invention may be used in an infusion system of a medical application and is serial connected in the infusion system. In a process of the infusion, medical liquid flows into the drip infusion. The pressure sensing module senses an amount of the medical liquid drops and transfers a signal to a computer server of a hospital or a build-in micro-chip for calculating. The present invention may calculate a flow rate of the infusion and a stop or a backflow of the infusion, which is an automatic monitoring infusion system and avoid accident during infusion.一種液體流量測量裝置,其頂部設有形如滴斗的滴液管,在滴管本體的周圍設有與內部相通的引壓通道,在引壓通道的外端設有壓力感測模組,在滴液管正下方設有壓力連通管,該壓力連通管的底端延伸至接近引壓通道內端的位置;當本發明用於微小流量測量管路時,可串接入小流量管路;當本發明使用於輸液系統時,是串接在藥液的輸液管路中,在輸液過程中,藥液會進入滴管本體內,壓力感測模組偵測藥液滴落數目,再將此訊息傳遞至醫院的後台或自帶的單晶片進行計算,可計算出輸液的流速、流量以及輸液是否停止或逆流,達到自動監控輸液過程的效果,避免意外的發生。10‧‧‧滴管本體11‧‧‧上存液管111‧‧‧上安裝座112‧‧‧引壓通道114‧‧‧線圈槽12‧‧‧下存液管121‧‧‧下安裝座14‧‧‧流量調整槽15‧‧‧帶孔板153‧‧‧出口槽154‧‧‧連接孔17‧‧‧感應芯棒18‧‧‧滴液管181‧‧‧尖端182‧‧‧滴嘴20‧‧‧壓力連通管21‧‧‧斗部22‧‧‧壓力連通孔30‧‧‧壓力感測模組41‧‧‧線圈管42‧‧‧感應線圈43‧‧‧電磁感應管50‧‧‧數據傳輸模組51‧‧‧無線傳輸單元60‧‧‧外蓋
