A tank gauging system is a method used to measure and monitor the level of liquid in storage tanks, such as those used in the oil and gas industry. There are different types of tank gauging systems available, but the most common method used is through the use of sensors.
The basic operation of a tank gauging system involves measuring the level of the liquid in the tank and converting it to a volume measurement. This is achieved using various types of sensors such as ultrasonic, radar, or capacitance sensors, which are installed on the tank’s surface or inside it.
When the liquid level changes, the sensors detect the change and send a signal to the tank gauging system’s control unit. The control unit then calculates the volume of the liquid based on the level measurement and the tank’s dimensions, taking into account factors such as temperature and pressure.
The tank gauging system also includes a display unit that provides real-time readings of the liquid level, volume, and other relevant data. This allows operators to monitor the tank’s contents and make informed decisions about refilling or emptying the tank.
