This invention relates to a method and apparatus for measuring the volume of a medium in a tank. A pipe is immersed into the tank to its bottom portion and this pipe has connection with a gas medium source, so that the tank medium existing in the pipe can be forced out of the pipe before the measuring takes place. The pressure in the immersed pipe is in a direct proportion to the liquid level in the tank and is measured by a pressure sensor/measuring unit, which is in connection with a computer and a printer. The invention also relates to the possibility to measure the volume of a second medium with another specific weight in the tank. |
