Flow meter turndown ratio

WebPercentage of measured value or actual reading. For example, a flow meter’s accuracy is given as ±3% of actual flow. At an indicated flow rate of 1000 kg/h, the ‘uncertainty’ of actual flow is between: 1000 – 3% = 970 kg/h. And. 1000 + 3% = 1 030 kg/h. WebThe turndown ratio - TR - for an orifice meter with maximum flow of 12 kg/s and a minimum flow of 3 kg/s can be calculated as: TR = (12 kg/s) / (3 kg/s) = 4. - normally expressed as turndown ratio of 4:1. This is a typical …
