Tank gauges are the components which are inserted in the tanks to know the level and temperature of any component present in the tank. They are used to calculate the volume, mass, level, temperature (spot temperature, product temperature, vapor temperature, ambient temperature and tank temperature stratification) and pressure (single pressure, multi-point pressure, vapor pressure , ambient pressure) of the product.

Automatic tank gauge systems are used to detect leakage in the tank. These leakages are detected by performing periodic tests in the period of 4-8 hours in which the tank is inactive. Due to the advancement in technology new gauge systems are made which can detect the leakage continuously without waiting for it to be inactive.

There is an increase in the demand for tank gauging systems because they provide great operational efficiencies, increase productivity and achieve enhanced accuracy.

It consists of a tank probe which is used to determine the product level and temperature, an electronical control panel which consists of a microprocessor which collects the information from the probes and interprets and analyzes it, a remote printer or an alarm or display monitor which shows the information provided by the microprocessor.

There is a high need of tank gauging systems because they provide information about the leakage in tanks with efficiency which can provide safety to the industries. Apart from providing safety it measures the temperature and level of the product. They are highly used because of their low cost and excellent  efficiency in detecting the faults.

The exposure of inventory tank gauging instruments to extreme climatic conditions is one of the major growth challenges in the market. Pollution, corrosion, temperature, salinity, and pressure affect the accuracy, reliability, and life span of level sensors when they come into contact with rough environments.

For a new level sensing technology to gain significant traction, it must optimize the mix of price, performance, and operation to offer a credible alternative to the venerable hydrostatic level sensor in an array of mainstream applications.

A microwave/radar level gauge as a drop-in replacement for a side-mounted hydrostatic level transmitter is not feasible, but it should be possible to achieve some degree of equivalency for other key characteristics. Hydrostatic level sensor emulation should be a priority for any supplier seeking to realize greater success in the process level marketplace.

The tank gauging system market is divided into seven regions, namely North America, Latin America, Asia Pacific, Europe, and Middle East and Africa (MEA).  Asia pacific is the leading region in terms of production and consumption of tank gauges because of India, china and japan followed by North America and Europe. All these regions are working on the new technologies which they can incorporate in these gauges. Latin America and MEA also holds a decent market share.
