A Method of Measuring the Flow Rate of Liquids and Gases and a Device for Exploiting the Method

摘要

The proposed method offers the possibility of measuring the weight consumption of a liquid or gas by means of measuring with a computing device the ratio of the drop in the pressure occurring on the pickup of an acoustic flowmeter and converted into an electric signal, to an electric signal from the acoustic flow meter. The flow converter of the pressure is connected in parallel to the acoustic flow meter; the measuring element of the flow converter is connected to one input of the computing device the other input of which is connected with the converter of the acoustic flow meter.
