High Precision Open Channel Flow Meter For Water Management
High precision open channel flow meters deliver reliable flow data essential for effective water management in agriculture, utilities, and environmental monitoring. Bulk purchasers value meters with advanced signal processing, robust construction, and flexible communication interfaces. These meters support compliance with water use regulations.
Reliable Non-Contact Flow Monitoring for Rivers, Canals, Stormwater & Industrial Discharge
What Is a High Precision Open Channel Flow Meter?
A high precision open channel flow meter is a non-contact measuring device used to determine the flow rate of liquids in open environments such as rivers, irrigation canals, and wastewater discharge channels. It uses ultrasonic or radar technology to calculate flow based on water level and channel geometry. These meters are essential tools for accurate water resource management, environmental monitoring, and compliance tracking in both municipal and industrial sectors.
By delivering real-time, highly accurate measurements (typically ±0.5 to ±1 percent), they support:
Smart water distribution in irrigation systems
Overflow detection in stormwater channels
Pollution control in industrial effluent monitoring
Regulatory reporting for environmental agencies
Optimization of treatment capacity in wastewater plants
