The metering of air and other gasses in manufacturing plants in the chemical process industries (CPI) is pivotal in many functional applications such as safety, process control, product quality, production efficiency, environmental compliance and costs. When the measurement of air or other gasses is not accurate or inconsistent, some potential results include dangerous accidents, emergency shutdowns, unplanned maintenance, production slowdowns or cost overruns. There are six to eight gas flow measurement technologies available today. Only about a few of them are ideal for the heavy-duty metering applications found in the most challenging CPI operations. Each technology comes with its own strengths and weaknesses, based on exactly what material is to be measured, the required accuracy, where it should be measured and so on. If an industry chooses the wrong flowmeter — in terms of extra maintenance, repairs and spares in large CPI plants — can lead to tens of thousands of dollars. If yo...
