Automatic Tank Gauging System (ATG)
Automatic Tank Gauging System (ATG) consists of a liquid level gauge controller, a magnetostrictive level gauge, a management server, management software, and other components. Through the tank level, the average temperature, and other data can be accurately measured, effectively managing gas station Invoicing And shift, and other business. The system can monitor 1-6 tanks simultaneously, fully realizing the closed measurement and data quasi-safety. Indeed, safety, at the same time, includes side leakage alarm, accident alarm, liquid level alarm, and other functions. Petrol stations can be full of monitoring, fully automated petrol station management, and intelligence.
ATG control box
The console is the interface of customer operation, and the display is also the data management and record center. The major units of the console are the power board, mainboard, touch screen, and safety barrier. Through the reduced voltage from the power board, it will supply a safety voltage and current status for the whole system.
Composition of the ATG control box
- TFT 8-inch color touchscreen, 800×600 resolution, graphical touchscreen control, intuitive and fast
- Core processing motherboard, Consists of high-end embedded processors and peripheral circuits, which are the data processing center of the entire liquid-level measurement system
- Safety barrier, The safety barrier is an explosion-proof safety isolation component, which outputs safe and reliable current and voltage to provide probe work
- Power module: The power module provides stable power to the entire control box
Main parameters of the ATG control box

ATG probe rod
The probe rod of the liquid level meter is also called the sensor. It is developed based on the principle of magnetostriction
Composition of the probe rod
It is mainly composed of magnetostrictive wire (waveguide wire), measuring rod, electronic chamber, and non-contact float (with a permanent magnet inside) on the rod
The structure is shown in Figure P1. When the sensor is working, the electronic chamber sends a “starting pulse”, which is transmitted along the waveguide wire and generates a rotating magnetic field. When the magnetic field meets the permanent magnetic field of the float, a magnetostrictive effect is generated, causing the waveguide wire to twist. The electronic chamber senses the twist and converts it into an “end pulse”. By calculating the time difference between the two pulses, the displacement is measured, thereby obtaining an accurate liquid level value.
