Instrument Overview

The HX-I Portable Open-Channel Flow Meter is a new type of portable instrument for measuring open-channel flow. It calculates instantaneous flow and cumulative flow based on the technical requirements specified in HJ/T15-2007, "Technical Requirements for Environmental Protection Products—Ultrasonic Open-Channel Wastewater Flow Meters." This meter is widely applicable to environmental monitoring stations at all levels, wastewater treatment plants, water conservancy agencies, water utilities, research institutes, and third-party operating companies for measuring standard weir-flume flows at wastewater discharge points and for comparing these measurements with data from online wastewater flow meters. It is also suitable for compliance with HJ 354-2019, "Technical Specifications for Acceptance of Online Monitoring Systems for Water Pollution Sources."

Product Features

128x64 graphic OLED display with high-definition, full-view angle, suitable for outdoor applications; built-in calendar and clock; password-protected parameter settings; automatic and manual measurement modes; printing function; remote communication control capability; 8 sets of measurement data (each set records continuous measurements for 8 hours), with data export functionality; historical data query feature; real-time battery level display.
