What meter type is recommended for customers with wide variation in water use?

• A. Single Meter
• B. Compound Meter
• C. Digital Meter
• D. Smart Meter

Answer: (B)

When a customer’s water use varies a lot, you need a meter capable of staying accurate across both very low and very high flows. A compound meter does this by combining two measuring paths in one device: a low-flow section that is sensitive to small amounts of water and a high-flow section that can handle larger volumes without losing precision. The total usage is read by combining the outputs from both parts, so accuracy is maintained whether the customer is irrigating lightly or running many fixtures at once. This makes it the best fit for wide variation in demand. A simple single meter can lose accuracy outside its optimal range, and digital or smart meters are technologies for data collection rather than inherently addressing the broad measurement range in a single device.
