Improve device of diaphragm type gas table error examination speed

The utility model provides an improve device of diaphragm type gas table error examination speed, including air inlet, data acquisition and processing module, diaphragm type gas literary name wheel counter, least count dish, photoelectric sensor and diaphragm type gas table gas outlet, the gaseous entering by diaphragm type gas table air inlet is examined the table, and photoelectric sensor arranges in before the diaphragm type gas table for the reflex reflectors that the least count coiled on the measurement diaphragm type gas literary name wheel counter, photoelectric sensor detect reflex reflectors or blackstreak sign that diaphragm type gas literary name wheel counter least count coiled, and the collection of data acquisition and processing module obtains photoelectric sensor's output pulse, and the gas of emission is by the gas outlet discharge of diaphragm type gas table, reflex reflectors be N, the blackstreak sign be N, this method is simply convenient, be difficult for makeing mistakes, and follow -up data processing is also comparatively simple.
