Principle of operation.

The conveying with a single vessel is carried out discontinuously. The pressure vessel is filled first. Der Druckbehälter wird zuerst gefüllt. The filling level is determined either by a level detector or by weight signal. After that compressed air is fed into the system, which transports the product through the pipeline. After carried out batch conveying the procedure is repeated.

The continuous conveying can be carried out by using two pressure vessels. One sender will be filled while the other one is conveying.
