Thermal Meter Liquid Flow Meters
Description
Thermal meter liquid flow meters are devices used to measure the flow rate of liquids by utilizing the thermal properties of the fluid. These meters apply a measured amount of heat to a sensor, and the interaction between the heat and the fluid is used to determine the flow rate.
Working Principle
Thermal flow meters operate by using heaters and thermal sensors to measure the flow of fluid through a pipe. A specific amount of heat is applied to the heater, and as the fluid flows, heat is transferred from the heater to the fluid. The rate of fluid flow is determined by the amount of heat absorbed by the fluid. The heat transfer is more pronounced in turbulent flow conditions, allowing for easier measurement as the flow rate increases .
