In this paper,according to JJG 693-2011 Combustible Gas Detection Alarm,aiming at the large meas-urement error of glass float flowmeter,the design scheme of selecting appropriate flow measurement limit,fixed point measurement and gas path switching is proposed,and the intrinsically safe combustible gas dilution device is developed to solve the difficult problem of calibration of combustible gas detection alarm in complex field.
