British thermal units (BTU), a fundamental indication for calculating thermal energy in residential and commercial buildings, are precisely measured by electromagnetic BTU meters. The thermal energy used by chilled water is measured in BTUs. BTU meters are often used for HVAC, heating, chilled water systems, and other applications in commercial, industrial, and office buildings.
01
Electromagnetic BTU meter
The heat energy transported in a heating or cooling system is measured using an electromagnetic BTU (British Thermal Unit) meter. It uses temperature sensors in conjunction with electromagnetic flow measuring methods to function. The temperature and flow sensors make up the meter. The volumetric flow rate of the fluid—such as water or glycol—moving through the system is measured by the flow sensor using electromagnetic induction. Determining the quantity of heat energy being transmitted requires this information.To monitor the temperature differential, temperature sensors are usually mounted at the system's input and outflow. The BTU meter can determine the quantity of heat energy exchanged with accuracy by integrating the data on flow rate and temperature differential. Common uses for the electromagnetic BTU meter include industrial operations, HVAC (Heating, Ventilation, and Air Conditioning) systems, and district heating and cooling systems. It offers a precise and trustworthy way to assess energy use, making energy management and billing more effective.It is essential for controlling and keeping an eye on how much energy is used across various applications.

Reliable Electromagnetic Flow Meter Guide
Electromagnetic flow meters detect flow by using Faraday's Law of induction. Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage).This is the quantity of heat energy needed to increase a pound of water's temperature.

03
Electromagnetic Flow Meter Calibration
The heat energy transported in a heating or cooling system is measured using an electromagnetic BTU (British Thermal Unit) meter. It uses temperature sensors in conjunction with electromagnetic flow measuring methods to function.Place the master meter in series with the flow meter under test.
Principle Electromagnetic BTU meter
Principle of operation of the electromagnetic BTU meter (Heat meter): Heat exchange occurs when hot (cold) water from a heat source flows into a system (heat exchanger, radiator, or complex system made up of them) at a high (low) temperature. Heat is then released or absorbed by the user through heat exchange (note: this process includes energy exchange between heating system and cooling system).When water flows through the heat exchange system, the system heat release or absorption is shown based on the flow sensor’s readings and the temperature of the sensor, which matches the temperature of the return water. The system heat release or absorption is also calculated over time using a calculator.
