Energy metering and management is a major area for flow measurement that requires measuring all fluid types, and also requires using different types of flowmeters. District heating and cooling, compressed air measurement, and heating, ventilation, and air conditioning (HVAC) make up a major portion of energy metering. These applications are used worldwide in every region, because energy metering is a requirement for residential, commercial, and industrial buildings. In this article, by Jesse Yoder of Flow Research, Jesse discusses how facilities are moving toward an integrated approach to energy metering.
