turbine gas meter

La description

Nominal diameter：DN*5(1″)-DN**0(8″)ï¼› Flux range：2.*****0 m3/hï¼› Pressure grade：1.6、2.5、4.0MPaï¼› Shell material：aluminum alloy or stainless steelï¼› Inner electrical source：3.6VDC Li-battery，screen real time display the battery capacity percent(tendency value)for promoting consumer to change batteryï¼› Outer electrical source：***4VDC，ripple≤*0mV，when meet outer electrical source，inner electrical source would cut-off by itself，whole machine will be supplied power by outer electrical sourceï¼› Impulse signal（three-wire system）：match with instantaneous deliveryï¼› （***0）mA standard analog signal：connection mode two-wire system or three-wire system，power supply mode is **4VDC outer electrical sourceï¼› Standard flux signal：through impulse signal mode output，each impulse delegates 0.1m3或1m3 capacity。Be the same with IC card to support usingï¼› RS***5 interface signal：directly networking with up grade computer, it can transfer the temperature, pressure, instantaneous flux of measured medium, standard volume gross, meter related parameters, accident code, running state and real time data。With special MODEM support using, it can implement telephone communication, one special MODEM could match 8 flux meters.
