WebIt is important to choose a meter that will operate in 60% to 80% of the meter’s flow range most of the time to avoid inaccuracies associated with flow rates that are at the upper and lower end of the meter’s capability. Rotameters are usually limited to a 10:1 turndown ratio, which means they cannot accommodate a wide variation in flow rates. Web4 aug. 2012 · Valves are often not required to handle the maximum possible flow and the term turndown is used for the ratio: For example, a valve might be required to handle a maximum flow which is 70% of that possible. With a minimum flow rate of 2.0% of the maximum flow possible, then the turndown is 70/2.0=35. View chapter Purchase book
