It can be used to measure the stock, namely the determination of the total amount of product in the tank level gauge system can also be used to turn the output measure, that is, as product marketing and tax basis. The main two methods: measurement based on volume and quality. Tank gauging system based on volume, the stock of measurement achieved by measuring the liquid level and temperature. In the tank gauging system based tank level controller on quality, the stock is measured using a liquid measuring hydrostatic liquid column made​​. In turn inventory control measurement or lose, no matter what method, the reliability and accuracy of measuring instruments is very important.
