Open channel flow measurement
Accurate open channel flow measurement for wastewater applications
Open channel flow measurement is an essential part of wastewater monitoring. Accurate flow data allows organisations to calculate discharge volumes, optimise treatment processes and comply with environmental regulations. Whether monitoring sewer systems, wastewater treatment plants or industrial discharge points, reliable flow measurement provides the foundation for effective water management.
TEC42 delivers advanced open channel flow measurement solutions that combine high accuracy with reliable long-term performance in demanding environments.

What is open channel flow measurement?
Open channel flow measurement determines the flow rate of water or wastewater in channels, partially filled pipes and sewer systems. Unlike pressurised pipelines, open channels require specialised measurement techniques that take both water level and flow characteristics into account. Open channel flow measurement is commonly used in:
- Wastewater treatment plants
- Municipal sewer systems
- Industrial discharge points
- Stormwater monitoring
Accurate flow data enables operators to better understand system performance and improve operational efficiency.
Reliable monitoring under all conditions
Wastewater environments are often unpredictable. Rainfall, changing production processes and varying flow rates can all influence measurement accuracy.
TEC42 develops reliable flow measurement systems that continue to perform under challenging conditions. Our solutions provide accurate data while requiring minimal maintenance, making them suitable for continuous monitoring applications.
Integrated monitoring solutions
Flow measurement becomes even more valuable when combined with automatic wastewater sampling. By integrating both technologies, organisations obtain complete information about wastewater quality and discharge volumes. This supports:
- Environmental compliance
- Process optimisation
- Accurate reporting
- Better operational decision-making
