The advantages of ultrasonic flow meters include ease of use and quick and easy installation. In ultrasonic flow measurement, the measurement takes place in the process from outside the piping with surface-mounted sensors. The sensors are easy to install because the measurement takes place from outside the piping and the installation does not require piping modifications or cause additional connections that are potential leaks. Because the measurement takes place from outside the pipeline, the installation of the measurement does not cause process interruptions, nor pressure loss. The measurement is thus also hygienic. Acid-resistant, robust sensors provide a reliable, highly repeatable and reliable measurement that is independent of fluid, conductivity and pressure. Katronic's ultrasonic flowmeters have a unique sensor placement function that facilitates installation.
