The open channel flow integrating instrument is a versatile, intelligent device designed for industrial use. It offers optional linear signal outputs, including 4-20mA, 0-20mA, 1-5V, and 0-5V, as well as RS485 serial output. The instrument integrates a two-line control module for signal input, allowing separate control of each line signal and performing relative operations for display and output. With open channel flow processing functionality, it can be used as an open channel flow meter. Additionally, it supports data downloading via a flash disk, offering flexible usage.

  • High precision, non-contact level measurement, unaffected by flow velocity.
  • Low sensor power consumption, easy installation and orientation, widely applicable.
  • Suitable for wall-hanging right-angle rectangular weirs, triangular weirs, Parshall flumes, and more.
  • Easy operation with minimal parameter setup, no need for input signal calibration.
  • Full functionality with 2-line relay output, compatible with actuating mechanisms like motors and warning systems.
  • Flow integrating instrument with data storage; retains data for up to 10 years during power loss, with optional SD card storage.
  • Customizable sensor options for anti-erosion, anti-explosion, small blind area, ultra-low power consumption, or wide range.
  • Can be equipped with a flash disk, micro printer, and storage battery based on user needs.
