\n\t\t\tEXACTSONIC II – PORTABLE ULTRASONIC FLOW METER FOR LIQUIDS
\n\t\t<\/h2>\n

\n\t\t\tThis principle of measurement is also referred to as the transit time difference method. For measuring the flow rate of liquids using this technique, ultrasonic pulses are sent and received simultaneously through the medium in the direction of flow and against it. The sensors work alternately as transmitter and receiver. The transit time of the acoustic signals filtered through the medium in the direction of flow is shorter than that against it. The difference in transit time Δt is measured and can be used to calculate the average flow velocity of liquids filtering through the acoustic path. After measuring the flow velocity and with the pipe cross-sectional area, volumetric flow can be calculated.\n\t\t<\/p>\n

\n\t\t\tThese ultrasonic flowmeters have many benefits, for example, the measuring instruments produce accurate results in just a matter of minutes, they are easy to install and operate, there is no process interruption and there are no pipe restrictions. As a result, there is no pressure loss and therefore, time and cost savings as the ultrasonic flow meter is easy to install on the pipe.\n\t\t<\/p>\n
