Dear Sir,thank you for your attention.we are an engineering Company in Iran about instruments , there are some big projects for CNG station in our country at the mament we need to find good & expert manufacturers about CNG Application especially CNG Flow meters. please note we need this product about 5000 pcs in each year. please find our request complete at below & offer us your best specification.in order to measure accurately the consumed gas in CNG station we need to use flow meter in dispensers. the flow meter should be direct mass meter therefore unaffected by gas composition or pressure . because of rapid variation in pressure ,temperature , gas density and flow during the filling and the potential for variation in gas composition over time or by location it is recommended to use direct mass meter. Flow meter with sensor & transmitterInstalation : in hazardous ZoneHumidity: 5% to 95%Process Fluid Temperature: -40 to 125 degree centigradeAmbient Tempreature: -20 to 50 degree centigrade Power supply: 24 vdc or auto switching AC/DCout put: modbus, 23-digit precisionFlow Direction arrows: yesvibration limit : according to IEC 68.2.6 Endurance sweep 5 to 2000 HZ, 50 Sweep Cycles @ 1.0g sensor grounding leads: must have a low impendence (under 2 ohms)Flow range: 1...20 kg/minbatch accuracy: +/- 1.0% of rate repeatability : + / - 1.0% of rate zero stability: 0.009pressure limit: 375 bar again thank you for your attention & we hope we could find good supplier.
