Process Engineers have a wide choice of technologies and products at their disposal for custody transfer flow measurement, a transaction involving transporting physical substance from one operator. Newer flowmeter technologies such as coriolis and ultrasonic offer increased reliability, reduced pressure drop, and high accuracy. At the same time, flowmeter suppliers are making improvements in the performance of meters using more established technologies. Turbine flowmeters, for example, are being made with stronger bearings, offering longer life. Paul Everett at IMS Research comments, “differential pressure (DP) flowmeters appear to be holding their own. DP flowmeters still have the largest installed base of any…
