PROBLEM TO BE SOLVED: To provide a piston type syrup meter of a drink dispenser wherein syrup is diluted with diluting water such as water, soda water, thereby supplying a drink, wherein even if the viscosity of syrup changes, feed rates of syrup can be controlled in a stable manner so that a drink having a proper dilution ratio can be supplied. SOLUTION: By providing, in the drink dispenser, a magnetic member 19a of a piston 19 of a piston type syrup meter 16 for use in the drink dispenser, magnetic sensors 20a, 20b to sense that the piston 19 has moved to one of the opposite ends of a cylinder 18, and a feed control part 100 to output a control signal for changing over the moving direction of the piston 19 according to the sensing outputs of the sensors 20a, 20b, syrup of a constant volume can always be delivered even if the viscosity of the syrup varies. |
