This flow meter is built to withstand the rigors of both industrial and commercial settings, with a robust design that supports continuous operation in high-pressure and high-temperature environments. With its versatile communication options and ease of integration into existing energy management systems, it stands as an essential tool for accurate thermal measurement.
Working principle
The LDGR Electromagnetic BTU Meter operates on the principle of electromagnetic flow measurement. It utilizes Faraday’s Law of Induction, which states that when a conductive fluid flows through a magnetic field, a voltage is induced proportional to the flow rate. This is measured by the sensor electrodes.
The meter integrates this flow measurement with temperature sensors to calculate thermal energy (BTU). By simultaneously monitoring the temperature difference between the incoming and outgoing fluid, the meter uses the formula:
BTU=Flow Rate×Temperature Difference×Specific Heat Capacity
This ensures precise energy consumption data, which is crucial for evaluating energy efficiency and optimizing usage in heating, cooling, and industrial processes.
