Flow meter turndown
http://timer.flowathletics.com/ In flow measurement, the turndown ratio indicates the range of flow that a flow meter is able to measure with acceptable accuracy. It is also known as rangeability. It is important when choosing a flow meter technology for a specific application. If a gas flow to be measured is expected to vary between 100,000 m³ per day and 1,000,000 m³ per day, the specific application has a turndown ratio of at least 10:1. Therefore the meter requires a turndown ratio of at least 10:1. For exampl…
