With the rapid increase of the number of motor vehicles and the further opening of the retail market of refined oil products, the demand for refined oil products has increased steadily, and the number of gas stations has also increased in step. By 2022, the number of gas stations in our country has already reached 119,000.

In view of the dangerous characteristics of flammable and explosive oil, gas stations are also classified as dangerous chemical business units with storage facilities, such as unloading, refueling and other operations in the event of oil spills, it is easy to cause fire and explosion and other dangerous accidents. Therefore, in order to further improve the risk prevention and control capabilities of flammable and explosive places and strengthen the safety management of gas stations, the Ministry of Emergency Management approved the issuance of the AQ 3010-2022 Safety Code for gas stations, the 2023 is scheduled to commence on 1 April.

The new safety code for gas station operations removes the rule that“Mobile communication devices should not be used in gas stations” and adds security requirements for mobile phone payment by scanning codes, allow mobile phone payment with combustible gas acousto-optic alarm. These include:

A refueling area equipped with a combustible gas sound and light alarm device may allow customers to pay by mobile phone. When an on-site alarm is sounded, the use of mobile phone and refueling-related operations should be stopped immediately, and according to the Emergency Plan for emergency disposal. The design of combustible gas detection and alarm shall comply with the provisions of GB/T 50493.

The traditional combustible gas acousto-optic alarm device needs regular adjustment, and has the false alarm to miss the report, after using for a long time, will have the drift phenomenon, can not guarantee when the handset pays the effective operation. So you need a long-life combustible gas detector that doesn't need to be tuned.

For the safety of gas stations and the new requirements, Hanhai photoelectric developed a point laser methane sensor. This product does not need to adjust, the service life of up to 10 years. Is a more secure and reliable, low-cost integrated new technology products.

Point laser methane sensor

On-site visualization of gas monitoring concentration

With the display screen, the scene can be real-time display gas monitoring concentration, timely to avoid the occurrence of potential accidents.

Sound and light on-site alarm more intuitive

With on-site sound and light alarm function, fault prompt function. Gas leak the first time to remind the user, do a good job in a timely manner on-site staff evacuation.

More diverse means of communication

Can choose wired communications (RS485 or 4-20ma) , wireless communications (NB-Iot or 4G) , GPS or bluetooth communications, adapt to a variety of communication scenarios.

High protective performance

IP68 protection of the highest level, explosion-proof level up to Exd I a IIC T 6GB.
