With the temperature, the relative humidity and the dew point , mobile and stationary dew point measuring devices made by BEKO TECHNOLOGIES precisely measure the critical parameters in compressed air and other gases.
Two temperature sensors are installed in series in the direction of flow. The first temperature sensor measures the current process temperature of the compressed air, while the second sensor is electrically heated to a temperature that is 40 K higher than that of the first sensor. Higher volume flows results in a quicker drop in temperature at the sensors, so that the electric heater of the second sensor must increase its heat output. The electric energy required to maintain the temperature difference is proportional to the volume flow. This energy consumption is converted to provide the relevant flow measurements.
