Abstract
In a flow meter for an electric drug injection pump and a method for measuring a flow using the flow meter, the flow meter includes a lower case, an upper case and a temperature sensor part. A plurality of grooves and an extending groove are formed in the lower case. The grooves are spaced apart from each other. The extending groove extends along the grooves and a tube is positioned in the extending groove. The upper case faces the lower case and is combined with the lower case, to fix the tube. The heater is positioned at one of the grooves, to supply a heat to a fluid passing through the tube. The temperature sensor part is positioned at each of the grooves, to measure the temperature of the fluid passing through the tube. The tube is positioned to make contact with the heater and the temperature sensor part.
