Flow measuring device

The utility model discloses a flow measuring device. The flow measuring device comprises a miniature tubular flowmeter and a differential pressure transmitter, transmitter connectors are arranged at the H end and the L end of the differential pressure type transmitter, and the transmitter connectors are connected with the two ends of the miniature tubular flow meter through pressure guiding pipes.The miniature tubular flowmeter does not interfere with the real-time distribution of fine particles due to the fact that the miniature tubular flowmeter is not provided with an insertion type throttling piece. Meanwhile, due to the fact that no throttling piece is arranged in the measuring process, the fluid does not generate violent pressure changes, and the phenomenon that measurement cannot be conducted due to the fact that dust is accumulated at the pressure taking opening is overcome. 本实用新型公开了一种流量测量装置，包括微型管式流量计、差压式变送器；所述差压式变送器的H端和L端设有变送器接头，所述变送器接头通过引压管与微型管式流量计的两端连接；本实用新型微型管式流量计因没有插入式节流件，不会干扰到微细颗粒物的实时分布。同时，在测量过程
