Flow meters should be read?

• A. daily at the same time
• B. weekly
• C. monthly
• D. when readings seem off

Answer: (A)

Tracking flow effectively relies on keeping a steady, comparable data set. Flow in a wastewater plant varies throughout the day, so reading the flow meter daily at the same time creates a consistent snapshot that helps you see true trends, catch anomalies early, and verify the meter is functioning correctly over time. Reading only weekly or monthly can miss short-term fluctuations that impact process control and reporting, and waiting until readings seem off delays detection of sensor or hydraulic issues. So, daily readings at the same time is the best approach.
