To measure air and gas flows accurately and reproducibly, many parameters have to be correct. Therefore, the positioning of the sensor decisively determines the quality of the measurement results.
The gases to be measured also determine the choice of the right sensor. In safety-relevant areas such as the chemical industry the requirement for explosion protection has also to be considered which means that the selection of a suitable sensor is very limited.
