      The Sondar SF-500S is an ultrasonic non-contacting flow meter designed for open channel applications. It operates on the principle that the water level is specifically related to flow rate in standardized flumes and weirs. Using this principle, the SF-500S measures water level, calculate flow, and displays accurate instant/total flow rate. The unit provides a variety of weirs and flumes formulations for use in different applications.

      The Sondar SF-500S has a measurement range from 0.00 to 200,000.00 m/h with an accuracy of 0.2% of F.S. The measured flow information is saved in the memory of SF-500S and it can be downloaded by USB or transmitted by the digital communication such as RS232, RS485 or Modbus.

      The Sondar SF-500S non-contact, ultrasonic flow meter utilizes the Sondar LXD-04 sensor for open channel flow, it provides accurate level reading.

      Applications of the Sondar SF-500S Ultrasonic Flow Meter
      • Parshall flumes
