Supmea electromagnetic BTU meters accurately measure the thermal energy consumed by chilled water in British thermal units (BTU), which is a basic indicator for measuring thermal energy in commercial and residential buildings. BTU meters are usually used in commercial and industrial as well as office buildings for chilled water systems, HVAC, heating systems, etc.
High accuracyElectromagnetic flow meters offer high measurement accuracy and can be used to accurately measure conductive liquids in a wide range of flow rates.
Wide range of applicationsElectromagnetic flow meters are suitable for flow measurement of a wide range of conductive liquids, including acid and alkali solutions, water, sewage and so on.
Simple maintenanceElectromagnetic flow meters have no moving parts and are unaffected by changes in temperature and pressure, making maintenance and calibration relatively simple.
No pressure lossSince there are no flow-obstructing parts in the measuring tube, the electromagnetic flowmeter causes no additional pressure loss to the fluid.
Digital Signal ProcessingAdopting advanced microcontroller technology, digital processing of measurement signals improves the stability and reliability of measurement.

An electromagnetic BTU (British Thermal Unit) meter is a device used to measure the heat energy transferred in a heating or cooling system. It operates based on the principles of electromagnetic flow measurement combined with temperature sensors.
The meter consists of a flow sensor and temperature sensors. The flow sensor uses electromagnetic induction to measure the volumetric flow rate of the fluid, such as water or glycol, passing through the system. This information is crucial for determining the amount of heat energy being transferred.
The temperature sensors are typically installed at the inlet and outlet of the system to measure the temperature difference. By combining the flow rate and temperature difference data, the BTU meter can accurately calculate the amount of heat energy exchanged.
