Thermal Mass Flow Meter

Thermal Mass Flow Meter Applications and the Industries ServedThermal mass flow meters are popular in industrial applications because of their design. They have no moving parts, require no temperature or pressure corrections, and retain an excellent accuracy over a substantial range of flow rates. Additionally, whenever there is a limited straight run, common in many industrial applications, and a developed profile cannot be achieved, flow conditioning can solve the issue. Flow conditioning can create a known and repeatable velocity profile and enhance the flow meter’s accuracy.
