What are secondary flow elements primarily used for?

Secondary flow elements are primarily utilized to reduce turbulence in stilling wells. These elements help create a smoother flow by disrupting excessive motion of the water, which can lead to inaccuracies during flow measurement. By minimizing turbulence, they enhance the reliability of the readings taken from flow measurement instruments, ensuring that the data collected accurately reflects the true flow conditions.

The design and placement of secondary flow elements in stilling wells are crucial. They create a controlled environment where disturbances caused by incoming flow are minimized, allowing for better measurement of flow rates and levels. This is particularly important in wastewater treatment processes, where precise measurement is essential for operational efficiency and regulatory compliance.
