Badger Meter Europe's 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. By placing the temperature sensors across the load, and measuring the flow in the loop, the BTU meter will measure the energy consumed.

The Model 2300 BTU meter is a microprocessor-based unit. It displays two lines of information such as flow rate, flow total and BTU total. The software is menu-driven and allows for easy programming and calibration in the field. A password lock is also provided to limit access to the programmed settings.
