The Electromagnetic BTU Meter is a reliable instrument for measuring the British Thermal Units (BTU), which represents the heat energy in a system. It functions based on the electromagnetic induction principle. When a conductive fluid, like water with dissolved salts, flows through a magnetic field created by the electromagnetic flowmeter, an electromotive force is induced. This induced voltage is proportional to the flow rate of the fluid. By simultaneously measuring the temperature difference between the inlet and outlet of the fluid in the heating or cooling circuit, the BTU value can be accurately determined. The Electromagnetic BTU Meter is known for its high accuracy over a wide range of flow rates. It is resistant to fouling and can operate in harsh environments. It finds extensive use in district heating systems, large - scale industrial plants, and power generation facilities where accurate heat measurement is essential for efficient energy distribution and consumption monitoring. Its compatibility with modern data acquisition systems allows for seamless integration into comprehensive energy management setups.
