Thermal Mass Flow Meter for Gases Model KES Field of Application The KES type series thermal mass flow meters measure the flow of gases, independent of variations in process pressure and temperature. The flow meters are available in different versions for pipe nominal sizes from W to DN 200, pressures up to 16 bar and gas temperatures up to 175 °C. Measuring Ranges Flow velocitiy m/s (at 0 °C, 1,013 bar absolute) Theory of Operation The KES probe consists of 2 sensors: a temperature sensor for sensing gas temperature, and a sensor for measuring flow velocity. This sensor element is heated by...
