PROBLEM TO BE SOLVED: To accurately control the flow rate of syrups which have different viscosity depending on the type and whose viscosity changes greatly by a temperature change as to beverage supplying equipment which makes a beverage by diluting a syrup with water or soda. SOLUTION: A syrup is supplied to a multi-valve 19 while the syrup is being measured by syrup meters 1-4, and a predetermined amount of water or soda is supplied to the multi-valve 19. The syrup meters send out a constant amount of syrup each time a piston moves from one end to the other alternately in a cylinder having a port opening on both sides. The dilute water is supplied until the water flow meter 5 measures a predetermined amount while the flow amount is kept constant by a flow amount controller. The syrup is supplied until the piston completes a predetermined number of operations, and in doing so, on the basis of the flow amount of the dilute water per unit hour, the syrup meter operation cycle is adjusted for finishing simultaneously the supply of the dilute water and the syrup. |
