The SUTO S462 ultrasonic clamp-on flow sensor for water and other liquids is a highly cost-effective and easy-to-install solution for measuring liquids. The sensor is available for pipes with diameters ranging from DN10 to DN40. The S462 provides accurate measurement of flow rate and fluid consumption without interrupting the process, causing pressure loss, or contaminating the measured medium.
Installation takes only a few minutes thanks to the clamp-on technology. The compact design allows the sensor to be installed even in confined spaces.
The S462 flow sensor connects to any monitoring system via an analog output and/or Modbus/RTU interface. The S462 is also compatible with SUTO’s S331 and S551 displays and data loggers.
Equipped with an OLED display and keypad, the S462 allows for easy on-site parameter configuration. Settings can be locked to prevent unintended changes. The display orientation can be inverted for easy readability regardless of the installation direction. The S462 stores daily, weekly, and monthly consumption statistics over a long period of time, which can be retrieved via the local display or interface.
