Description

Brief Introduction to product: The intelligent gas meter is electromechanical integration intelligent gas metering instrument which is developed by ZheJiang SanZhou Gas Meter limited company. It is suitable for automatic metering and toll control of city piping gas, nature gas and liquefied petroleum gas. It measures accurate and performance is stable and trustiness. It is a Ideal measuring product for improving modernization management level of the city gas management department. This product accord with regulation of GB/T********7 "diaphragm gas meter", CJ/T**2 â�� ***0 "IC card household diaphragm gas meter ". GB ***6.*****0 "Electrical apparatus for explosive gas atmospheres*-Part 1: General requirements ", GB ***6.*****0 "Electrical apparatus for explosive gas atmospheres*-Part 4: Intrinsic safety ". 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.*5 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.
