The fuel dispenser is one of the primary pieces of equipment at a petrol station, playing a crucial role in the delivery, measurement, and security of fuel supply. Fuel dispensers originated in the early twentieth century, evolving from the initial hand-cranked pump dispensers to today's diverse range of self-flowing fuel dispensers, self-priming fuel dispensers, and submersible fuel pump dispensers. The early transparent cylinder measurement systems have gradually developed into flow meters with pointer readings and mechanical counters, ultimately leading to the current computer-based counting devices equipped with electronic sensors. Over time, fuel dispensers have undergone significant qualitative changes in terms of design, functionality, ease of operation, measurement accuracy, and safety.
With the advancement of integrated circuit technology, Japan's Tocum (Tatsuno) company pioneered the launch of the electronic metering control dispenser in 1972. This innovative device utilized electromagnetic sensors to collect real-time flow signals, reducing measurement error to ± 0.5%. In the 1980s, the rise of microprocessor technology led to the development of the temperature compensation algorithms to automatically adjust for the coefficient of expansion of fuel volume. Additionally, it featured LED displays for real-time calculations of monetary amounts and introduced multi-gun, multi-oil management systems, significantly enhancing operational efficiency. The technological breakthroughs achieved during this period laid the hardware foundation for the subsequent integration of tax-control functions.
At the beginning of the 21st century, petrol dispensers delved into the depths of digitalization.
The accuracy of measurements has significantly improved: the use of Coriolis mass flow meters reduces measurement error to less than ±0.1%, while the multi-dimensional data fusion of temperature and pressure sensors enables dynamic compensation.
Payment Revolution: Technologies such as RFID (Radio Frequency Identification), license plate scanning, and facial recognition are transforming the transaction landscape, with contactless payments now accounting for over 70% of transactions.
The Internet of Things (IoT) control system enables real-time uploading of refueling data to the tax supervision platform via a 4G/5G module. It also incorporates GPS positioning to prevent the illegal relocation of equipment.
Safety Upgrade: Dual Discriminative Oil and Gas Recovery System (ORVR+Stage II) enhances the recovery rate of volatile oil and gas to 98%. Additionally, the static elimination device and emergency shut-off valve create a comprehensive multi-protection network.
