Product Introduction

The portable open channel flow meter is a high-precision measuring instrument specifically designed for hydrological monitoring, river flow measurement, agricultural irrigation, and municipal water supply and drainage industries. It supports measurement across 10 types of weirs and flumes, utilizing ultrasonic technology and a specialized ultra-low power consumption design combined with fully digital signal processing to ensure measurement stability and reliability.

This device offers a wide measurement range and high accuracy, supporting real-time data display, recording, export, and printing functions. Its user-friendly operation and high precision make it ideal for applications requiring frequent relocation during measurements.

Additionally, it complies with the JJG711-1990 verification regulations and references HJ353-2019, HJ354-2019, HJ355-2019, and HJ15-2019 to ensure its applicability and accuracy in water conservancy projects, environmental monitoring, agricultural irrigation, and other fields.

Applications include:
① Water conservancy departments: Monitoring flow velocity and volume in rivers, canals, and reservoirs.
② Environmental protection departments, water quality monitoring stations, and related environmental enterprises: Utilizing such equipment to monitor flow velocity and discharge in urban drainage systems and industrial wastewater discharges.
③ Third-party testing institutions: Performing field calibration and comparison of online open-channel flowmeter instruments.
④ Emergency management departments: Rapidly assessing water flow conditions to provide data support for flood control and disaster mitigation.
