Heat-Flow-Meter method for determining thermal ...

Feb 08, 2020· Thermal conductivity. Thermal conductivity is a measure of how well or poorly a material conducts heat. The rate of heat flow (dot Q) through a material can be determined by the following equation. In this equation, Δx denotes the thickness of the material along which the heat flows and A refers to the area through which the heat passes.

What is a Thermal Flow Meter and How Does It Work?

Feb 27, 2020· Thermal flow meters, using the thermal properties of the substance, measure the flow of a fluid flowing inside a duct or a pipe. Typically, a thermal flow meter introduces a specific amount of heat to its sensor. Some of the heat dissipates, and as the flow increases, the more heat will be lost, which will then be picked up by the sensor.
