PURPOSE: A flowmeter is provided to minimize resistance of fluid while rotating an impeller by forming an inlet port and an outlet port toward a rotating direction of the impeller. CONSTITUTION: A flowmeter comprises a case(2) having an inner space(4) by being formed as a cylinder shape; an inlet port letting fluid by being mounted on an opened unit of the case; an outlet port(8) discharging the fluid by interlocking with the inner space of the case; a protrusion(10) formed in the case toward a circumference direction; an impeller housing(12) located on the inner space of the case by being separated from the inlet port; a body(16) mounted on the housing; and a flange(18) formed on an outer circumference of the body. Thereby, the flowmeter minimizes resistance of the fluid while rotating the impeller by forming the inlet and outlet ports. Moreover, the flowmeter actively discharges the fluid letting in the housing. |
