151 BTU Electromagnetic Energy Meter

The Electromagnetic Energy Meter is a precision instrument designed for accurate measurement of thermal energy consumption in cooling systems. Combining advanced electromagnetic flow measurement technology with accurate temperature sensing, it continuously measures the flow rate and temperature difference between the supply and return lines to calculate the thermal energy transferred through the system. The Electromagnetic Energy Meter is ideally suited for HVAC systems, district cooling networks, commercial buildings, and industrial energy management applications, providing an efficient solution for energy monitoring, billing, and system optimization.
