Flow meter turndown ratio
WebTurndown ratio is often referred to as the rangeability of an instrument. It is defined as the ratio of the maximum capacity of measurement to the minimum requirement for measurement. It is expressed as a multiplication factor from the lowest range to the highest range. Ultrasonic flow meter usually has a turndown ratio of 250:1. WebJul 14, 2009 · Everything I find online or otherwise states that orifice plates have a turndown of 3:1 for 1% uncertainty, 4:1 for 2% uncertainty, and 10:1 for 5-10% uncertainty. The DP transmitters we typically use have a turndown of 40:1. It seems to me that the turndown of the transmitter itself would be the limiting factor of the flow measurement.

WebFor example, McCrometer’s ExactSteam™ V-Cone® is a DP-type meter configured for energy metering or mass flow with a flow accuracy of ±0.5 percent with up to a 50:1 turndown ratio. The ExactSteam™ V-Cone® … WebTurndown Ratio = maximum flow / minimum flow. For example, if a given flow meter has a 50:1 turndown ratio the flow meter is capable of accurately measuring down to 1/50th of the maximum flow. So, suppose a flow meter has a full scale rating of 20 ln/min the flow meter will measure down to 0.4 ln/min of flow. Keep in mind that the maximum and ...

Webft/second, and they rarely flow over 10 ft/sec. That means that a flow meter with a 20 or 30:1 flow rangeability from meter maximum, typically measures less than a 10:1 flow range in most actual processes. For gas applications, meter maximum flows are also much higher than typical process maximum flows. To achieve the advertised meter maximum ... WebTurndown Ratio / Rangeability is 1:100. Keep in mind that the maximum and minimum flow capability of a meter or controller is likely to be a greater span than the measurable and …
