Flow is one of the crucial parameters measured in process industries and water treatment plants, amongst other applications. For example, in water treatment plants where filtration equipment is cleaned periodically, a predetermined volume of water has to be pumped through filters. The GPM(Gallons per minute) value is multiplied by the duration of the cleaning process to measure the amount of water used for cleaning. A similar principle is used for measuring the amount of chemicals such as acids or caustic in a CIP(Clean in place) process. Accurate measurements of these chemicals ensure a successful cleaning operation without damaging equipment.
