PROBLEM TO BE SOLVED: To provide a simple and reliable flowmeter for fluid containing time variant components being employed in a milk line of an automatic milking system for animal, e.g. milking cow. SOLUTION: The flowmeter 10 measuring the quantity of liquid flowing through a line 4;6 comprises at least two conductive elements 12;12A, 12B, 12C. The conductive elements 12;12A, 12B, 12C are arranged on the line while spaced apart by some distance and connected with an electric circuit 14. Flow rate V of liquid is determined based on the conductivity G of liquid measured by the electric circuit 14, a time difference in the recognition of conduction, the interval between conductive elements in the line 4;6, and the actual electric resistance Rsw of liquid. |
