1. Description
The gas meter shell uses automobile galvanized sheet, which has stronger corrosion resistance; adopts automatic electrostatic spraying process, uniform spraying at one time, adding secondary anti-corrosion layer with beautiful appearance. The sealing ring of gas meter shell is made of stainless steel, the gas surface film adopts low temperature film, which is highly adaptable to ambient temperature; after the movement side cover is glued, rivets are used to strengthen the fixed connection to ensure that the small flow does not leak and the accuracy is qualified.
2. Product Performance
* High counting accuracy: It has dual display functions of mechanical watch and LCD screen, stable and reliable performance, and can effectively avoid user disputes caused by inaccurate measurement.
* Acrylic transparent windows are installed at the mechanical character wheel of the gas meter to prevent users from tampering with the mechanical character wheel and achieve the anti-theft function; the product adopts advanced controller glue technology to effectively prevent moisture, oil smoke, high temperature, and prevent gas meters The electronic device is damaged and the product is more stable.
* The controller is designed and manufactured completely in accordance with the national standard, using intrinsically safe explosion-proof circuit, and the gas meter is safer and more reliable.
* Using large-capacity farad capacitor as the valve closing energy source to ensure reliable valve closing in the case of battery undervoltage.
* The appearance of the product is beautiful and concise, and it is easy for gas companies to install at home. The gas meter housing has an anti-disassembly seal to prevent individual users from disassembling.
