Different Types of Tank Gauging System

Tank gauging systems are used to measure and monitor the level of liquids or gases in tanks, vessels, or silos. There are several types of tank gauging systems available, each with its own advantages and limitations. Here are some of the most common types of tank gauging systems:

Float and Tape Tank Gauging System: This is one of the oldest and simplest types of tank gauging systems. A weighted tape is suspended from a float that floats on the surface of the liquid in the tank. The tape is marked with graduations that indicate the level of liquid in the tank. This system is easy to install and maintain, but it requires manual reading of the tape, which can be time-consuming.

Servo Tank Gauging System: This system uses a servo motor to drive a measuring probe that is immersed in the liquid in the tank. The motor measures the level of the liquid by sensing the torque required to rotate the probe. The servo tank gauging system is accurate and provides real-time measurements, but it is more complex and expensive than other systems.

Radar Tank Gauging System: This system uses radar technology to measure the level of the liquid in the tank. A radar signal is transmitted from a sensor at the top of the tank, and the time taken for the signal to reflect back from the liquid surface is measured. This system is accurate and provides continuous measurement, but it is expensive and requires regular maintenance.

Hydrostatic Tank Gauging System: This system measures the pressure at the bottom of the tank to determine the level of the liquid. The pressure measurement is converted into a level measurement using a formula that takes into account the density of the liquid. This system is accurate and reliable, but it requires calibration for different liquids and operating conditions.

Optical Tank Gauging System: This system uses optical sensors to measure the level of the liquid in the tank. The sensors detect the amount of light that is reflected back from the liquid surface, and this measurement is used to determine the level of the liquid. This system is suitable for clean liquids and provides continuous measurement, but it is sensitive to changes in the optical properties of the liquid.
