What Are They?

Water and heat flow meters are devices used to measure the movement of water and, in the case of heat meters, the thermal energy transferred within a heating or cooling system. Water meters focus on accurately recording the volume of water passing through a pipe, while heat meters calculate the energy exchanged by measuring both flow and temperature difference.

Together, these technologies play an essential role in monitoring resource usage, improving energy efficiency, and supporting fair billing in building services and industrial systems.

How Do They Work?

Water flow meters typically measure the velocity or volume of water moving through a pipe using technologies such as ultrasonic, mechanical, or electromagnetic sensing. This is converted into a precise reading of total consumption or flow rate.

Heat meters take the measurement further by combining flow data with temperature readings from sensors installed in the supply and return lines. By calculating the temperature difference and flow rate, the meter determines the amount of heat energy transferred within the system.
