SUP-LDGR Electromagnetic BTU meter

• Specification

• Principle

The SUP-LDGR electromagnetic BTU meter (heat meter) operates with exceptional precision, leveraging an advanced principle to measure thermal energy efficiently. Hot or cold water, supplied by a heat source, flows into a sophisticated heat exchange system, such as a radiator, heat exchanger, or integrated network—entering at a high or low temperature and exiting at a reduced or elevated temperature. This process facilitates seamless heat release or absorption to the user through effective energy exchange, bridging heating and cooling systems with remarkable accuracy. As water circulates through the system, the flow sensor meticulously tracks the flow rate, while paired temperature sensors monitor the return water temperature over time. These values are processed by a high-performance calculator, displaying the total heat released or absorbed with clarity.

The energy calculation is defined by the formula:

Q = ∫(τ0→τ1) qm × Δh × dτ = ∫(τ0→τ1) ρ × qv × Δh × dτ

Where:

• Q: Total heat released or absorbed by the system, measured in joules (J) or kilowatt-hours (kWh).
• qm: Mass flow rate of water through the heat meter, in kilograms per hour (kg/h).
• qv: Volume flow rate of water through the heat meter, in cubic meters per hour (m³/h).
• ρ: Density of the water flowing through the heat meter, in kilograms per cubic meter (kg/m³).
• Δh: Enthalpy difference between the inlet and outlet temperatures of the heat exchange system, in joules per kilogram (J/kg).
• τ: Time, in hours (h).

This cutting-edge BTU meter is an indispensable tool for optimizing thermal energy management in residential, commercial, and industrial HVAC and heating systems, ensuring reliable performance and energy efficiency.
