In this way, by selecting the shape of the set of rotors housed in the main body 10 according to the type of liquid, it is possible to reduce the friction loss of the liquid passing through the pipeline.

Further, in the above-mentioned flow rate regulator and flow meter, the configuration in which the two rotors are housed in the main body 10 having an elliptical shape or a figure 8 shape has been described.
It may be formed by combining rotors other than two, or may be housed in a main body having a shape corresponding to the number of rotors. In addition, a vane type flow controller and a flow meter that house a rotor having a plurality of vanes in the main body and cause the syrup flowing between the adjacent vanes and the main body to flow out from the main body based on the rotation of the rotor. It may be.
