Performance characteristics

Product Features

Prepaid gas: pay first and then use gas to solve the problem of charging and household meter reading;

● Reminder function: When the remaining gas level and battery power are lower than the set values, it will prompt the user to purchase gas and replace the battery. When there is a fault, it will prompt an abnormal code;

● Alarm function: When valve, overcurrent, magnetic interference and other faults occur, the gas meter will give an alarm prompt in the form of sound and display;

● Information write back function: The gas meter can return gas volume information, meter status, and fault information to the information management system through an IC card, so that the gas company can understand the historical usage information of the user's gas meter;

● Anti hoarding function: can set gas purchase limits to prevent users from hoarding gas and reduce losses caused by gas price fluctuations for gas companies;

● Anti magnetic interference function: When external magnetic field interference is detected, the gas meter will automatically close the valve and cut off the gas supply;

Overdraft function: The software system can freely set whether to allow overdraft of gas usage.

Product Features

Accurate measurement: Using a wide range base meter with the three core components of Zhenlan, accurately measuring gas consumption and effectively reducing transmission differences;

High IP rating: Adopting a fully sealed structure with dust-proof and waterproof design, the IP protection level has been verified by authoritative testing to reach IP65, ensuring reliable use;

Ultra low power consumption: powered by three or four alkaline batteries, with a lifespan of over two years;

One meter, one card: The gas meter corresponds one-to-one with the user card to prevent unauthorized use, and the data is encrypted multiple times for security and reliability;

● Safe and reliable: Adopting the rolling edge pressing process of Zhenlan invention patent (patent number: ZL 2013 1 0029190.5), it has excellent sealing and anti-corrosion performance, strong resistance to internal pressure, and high safety;

● Easy to operate: The gas meter only requires simple settings to be used; The software interface is intuitive, with simple and easy-to-use operations such as account opening and gas purchasing;

Optional features: Mechanical temperature compensation and tiered gas pricing billing functions can be added according to requirements.
