Stop estimating consumption in your plant and get real, reliable flow data.<\/h3>\n
\n

\nThe S421 flow and consumption sensor is designed to deliver precise and stable measurement across a wide flow range. Thanks to its high resolution and fast sampling rate, it detects flow variations in real time, making it ideal for industrial applications that require continuous control.\n

\nInstallation is carried out using a dedicated measuring section with R-type threaded or flanged connections, ensuring an optimal flow profile and consistent results. The sensor can store two calibration curves, enabling operation with two different gases without compromising accuracy.\n

\nOptionally, the integrated color display allows simultaneous visualization of all measured variables and simplifies device configuration\u2014such as pipe diameter, gas type, and analog output scaling\u2014making commissioning fast and intuitive.\n \n\n\n<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div>
