Thermal Dispersion Technology for Airflow Applications

Thermal Dispersion technology is based on the principle that the amount of heat absorbed by a fluid is proportional to its mass flow. Thermal dispersion (mass) flow measurements are achieved by using two temperature sensors and a heat source located in a flow stream. By measuring the energy (heat) added to the flow stream and measuring the corresponding temperature change, mass flow can be derived. Thermal dispersion is a highly reliable and robust method for accurately measuring airflow velocities in today’s HVAC applications.
