Abstract
The utility model discloses a gas flowmeter which comprises a Venturi tube outer tube, a Venturi tube inner tube, a shell, a counting sensor, a data processing and displaying device, an impeller frame and an impeller. The gas inlet end of the shell of the flowmeter is provided with the Venturi tube outer tube, and the Venturi tube inner tube is arranged in the Venturi tube outer tube. The impeller frame is arranged in the shell of the flowmeter, and the impeller is installed on the impeller frame. The position, identical with the position of the impeller, on the shell of the flowmeter is provided with the counting sensor which is connected with the data processing and displaying device. According to the gas flowmeter, the gas inlet end of the shell of the flowmeter is provided with the Venturi tube outer tube and the Venturi tube inner tube, and the measuring precision and stability of low-velocity fluid are improved; the counting sensor is installed, the real-time flow and the accumulated flow of gas are calculated through pulse counting, and therefore measuring precision errors caused by the fact that a traditional gear set drives measurement displaying are avoided.
