A Btu Flow Meter is a specialized device designed to measure the amount of energy, or British thermal units (Btu), flowing through a pipe or duct. It does this by measuring the temperature difference between two points in the flow – usually before and after the point where the Btu reading is taken. This data can then be used for applications such as temperature control, energy management, and performance monitoring. With the increased focus on optimizing energy use and conserving resources, having an accurate Btu Flow Meter is essential for businesses to ensure they are getting the most efficiency from their resources.
