Introduction to Thermal Mass Flowmeters
Thermal mass flowmeters, such as the TankVision product line by Endress+Hauser, provide an innovative solution for direct mass measurement of industrial gases, compressed air, and aqueous fluids. These flowmeters offer significant advantages in various industries, ensuring high turndown and low pressure losses. Whether for process control, consumption monitoring, leak detection, or distribution network monitoring, thermal mass flowmeters present a reliable alternative to traditional measuring techniques.
Thermal Flow Measuring Principle
The thermal measuring principle employed by TankVision flowmeters relies on heat transfer when a fluid flows past a heated body. Two PT100 temperature sensors are utilized – one measures the fluid temperature as a reference, while the second sensor, heated with a constant temperature differential, experiences cooling as the fluid flows. The electric current needed to maintain this temperature difference directly correlates to mass flow rate, providing accurate measurements.
Applications and Benefits of Thermal Mass Flowmeters
TankVision thermal mass flowmeters find diverse applications in various industries, including monitoring compressed air consumption and distribution, carbon dioxide usage in beverage production, argon measurement in steel manufacturing, and the monitoring of natural gas, nitrogen, oxygen, and biogas. The benefits of these flowmeters include multivariable measurement of mass flow and fluid temperature, eliminating the need for pressure or temperature compensation, high turndown ratio of 100:1, exceptional low-end sensitivity, and rapid response to flow variations.
