Electromagnetic Heat Energy Meter for Heating and Cooling

The Electromagnetic Heat Energy Meter is a meter that measures the heat released by the heat-carrying fluid in the heat transfer system. Electromagnetic Heat Energy Meter is an inductive meter for measuring conductive media. It is suitable for measuring the volume flow rate of conductive liquids with a conductivity greater than 5us/cm.

The same Electromagnetic Heat Energy Meter can measure heat loss and cooling loss separately. In the heating system, only heat is measured, so it is called a heat meter; in the energy consumption measurement of central air-conditioning water, the loss of heat (winter) and cold (summer) is designed, so it is also called a cold heat meter.

Electromagnetic Heat Energy Meter working principle

The intelligent electromagnetic energy meter (electromagnetic heat and cooling meter) consists of a flow measurement unit, a heat calculation unit and a paired temperature sensor (PT1000).

The flow meter uses the Faraday electromagnetic induction principle to measure flow, and combined with the supply and return water temperature signals of the paired temperature sensor, it can calculate, accumulate, store and display the cold heat absorbed or released in the heat exchange loop.

The flow meter’s flow and energy calculation unit CPU and sampling module all adopt internationally advanced microcontrollers, which have large memory capacity and high equipment reliability. The heat calculation can truly realize consistent value calculation and achieve high accuracy. The complete set of matched temperature sensors uses platinum resistor Pt1000, and its matching error is ≤0.1℃

Paired temperature sensors (a pair of Pt1000 platinum resistance temperature sensors) are installed on the inlet and outlet pipes of the heat exchange circuit of the air conditioning or heating system to accurately collect the temperature values of the supply and return pipes and transmit signals.

Install the flow sensor (pipeline electromagnetic flowmeter) on the inlet or outlet pipe to accurately collect and calculate the flow value of the pipe network and transmit the signal.

Electromagnetic Heat Energy Meter working principle

The energy calculator is used to receive temperature and flow signals and calculate and store energy consumption. The effective data in the energy calculator (such as accumulated heat value, cooling capacity value, equivalent flow value, supply and return water temperature and temperature difference) is transmitted to the computer to realize intelligent management.

The computational mathematical model is:
Q=qmΔhdt

In the formula:
Q—heat released: kJ;
qm—the mass of the heat-carrying liquid flowing through the heat energy meter: kg/s;
Δh—the difference in specific enthalpy of the heat-carrying liquid corresponding to the inlet temperature and outlet temperature in the heat exchange loop: kJ/kg;
t—time: s

Electromagnetic Heat Energy Meter Applications

Electromagnetic heat energy meters, often referred to as electromagnetic flow meters combined with temperature sensors, are instruments designed to measure the energy used or supplied in heating or cooling applications. Here are their primary applications:

District Heating and Cooling Systems: One of the main applications of electromagnetic heat energy meters is in district heating and cooling systems. They help in monitoring and billing the energy consumed by individual units or households.

Industrial Processes: Industries often use heated or cooled fluids in their processes. These meters measure and control the amount of thermal energy being transferred to ensure optimal operation.

Commercial Buildings: In large commercial complexes like shopping malls or office blocks, they can measure the energy consumption of individual tenants or sections of the building.

Residential Buildings: Especially in multi-unit apartments, these meters can be used for individual billing purposes, ensuring that each resident pays only for the energy they consume.

HVAC Systems: Electromagnetic heat energy meters can be integrated into Heating, Ventilation, and Air Conditioning (HVAC) systems to monitor and optimize energy consumption, leading to more efficient system operation.

Data Centers: Due to the significant heat produced by servers, data centers often use liquid cooling systems. These meters can monitor the amount of thermal energy being removed, assisting in maintaining optimal operating temperatures.

Geothermal Energy Systems: These meters are pivotal in geothermal setups where there’s a need to measure the energy extracted from or returned to the ground.
