Abstract
To insure in a simple and economical manner a uniform and continuous dispensing of a fluid from a pressure tank, a method is provided according to which a pressurized gas is introduced into the pressure tank via a proportional valve that is disposed in an inlet line of the pressure tank, the pressure of the fluid located in an outlet line is measured with a first pressure sensor, and an outlet valve in the outlet line is opened and closed. The method also includes the determination of a set pressure value as a function of the measurement result of the first pressure sensor, the transfer thereof to the proportional valve, the measurement of the gas pressure in the inlet line with a second pressure sensor disposed between the proportional valve of the pressure tank, and the transfer of the measurement result to the proportional valve. The invention also provides an apparatus for carrying out the above method.
