Model 2300 Btu (British Thermal Units) meter monitors energy production or consumption in a circulation water loop by calculating the temperature difference between two temperature sensors and rate of flow from an impeller flow sensor. Typically, a hot water boiler or chiller acts as the system’s energy producer. The space in a building or a heat exchanger in some industrial process acts as the energy consumer. By placing the temperature sensors across the load as shown in the diagram, and measuring the flow in the loop, the Btu meter will measure the energy consumed. Theoretically, this would match the energy produced, if we ignore the losses in the piping between the energy producer and the load.
Model 2300 Btu meter is a microprocessor based unit. A non-magnetic, impeller flow sensor provides a frequency pulse that is proportional to flow. Two expansion slots are available for optional analog inputs, outputs, or serial communications. Up to four optional relays may be added for control outputs.
