Beschreibung
Zusammenfassung:	The invention discloses a flow measuring method for underwater medicament injection equipment, which comprises an equipment body, the equipment body comprises a medicament input joint, a pressure reducing part and a medicament output joint which are sequentially communicated through a runner, and the method comprises the following steps: firstly, introducing medicaments with different flows into the equipment body for calibration, and synchronously obtaining a plurality of calibration arrays; the calibration array comprises medicament calibration flow and calibration differential pressure before and after the medicament flows through the pressure reducing part; fitting the relationship between the medicament flow and the differential pressure according to a given formula to obtain a clear expression; and finally, the obtained real-time differential pressure is brought in to obtain the real-time medicament flow. The method has the remarkable effects that the relation between the flow and the differential press
