A flow meter includes a rotor housing (20) with a fluid inlet hole (14), a fluid outlet hole (15) and an inner groove formed between the fluid inlet and outlet holes. A separation plate (26) is partially inserted into the inner groove of the cylindrical body to prevent a fluid introduced into the rotor housing (20) through the fluid inlet hole (14) from directly discharging from the fluid outlet hole (15) and circulate the fluid along an inner wall of the rotor housing (20) before the discharging. A flying saucer-shaped rotor (70) is disposed within the rotor housing (20) at an inclined state by a predetermined angle. The rotor has an airtight inner space. A rotor shaft (72) is partially inserted into the rotor. A lever shaft (45) is connected to the rotor shaft (72) to transmit the rotation signal of the rotor to the outside. A rotor supporting shaft (61) is connected to the rotor shaft opposite to the lever shaft (45) to support the rotor. The airtight inner space of the rotor gives the rotor a buoyancy to compensate for a weight of the rotor shaft connected to the rotor. |
