Abstract
A method with its device to determine the pressure and circulation indices in a fluid by measuring a pressure difference between at least two measurement points, characterized by comprising the steps of dividing an auxiliary fluid stream into two divergent or branched streams at At the very least, drive each diverging stream to a respective measurement point and measure the difference in flow rate between the diverging streams, which difference is significant from the pressure difference between the measurement points.
