| This produce is a new generation radio frequency card gas
measurement instrument which is Manufactured by introduction
advanced technology of same trade at home and abroad. The designing
of radio frequency card solve the weakness of anti-interference
ability, attack tolerant and anti-destructive on card holder. The
surface of the meter is sealed completely not only preventing
water, oil and impurity from entering Internal of meter, but also
easy for cleaning. It is a Ideal measuring product for improving
modernization management level of the city gas management
department. Main Features 1. Structures Integrated Design, concise appearance, fluentness line. 2. Built-in Motor valve, the movement is precise and reliable. 3. Complete separation of sampling, service safety 4. Electricity shortage prompts: Showing lack of electricity if Voltage is less than 4.75 V; Shut the gas valve automatically, if Voltage is less than 4.0 V. 5. Gas shortage prompts: When the remaining gas in meter is less than 2m3, revealed that "lack of gas", and close the valve one time, Customer card can be anew open with informing user to Purchase gas. 6. Threefold dynamic passwords, secure, to prevent copying Main Technical parameter Nominal flow rate(qn) m3/h 1.6m3/h, 2.5m3/h, 4.0m3/h Measures range 0~9999.999m3 Measurement precision Grade B Maximum operate pressure(MPa) 10kPa Pressure loss(MPa) < 230Pa Normal operating pressure(MPa) 0.5~3kPa Data storage period > 10 years Display resolution 0.0002m3(0.2L) Working voltage DC4.75~6.3V Quiescent current <40uA Meter connector center distance 130mm |
