- The sensor is exposed to high temperatures and forces due to the gas flow. Due to the sometimes very difficult installation sites, special importance must be given to a long and maintenance-free operating time. Sensors without wearing parts are particularly economic.
- Exact and long-term stable measuring values : You need to rely on a correct quantity detection of gases. Even after using the device for years, the measuring values must be correct like on the first day. A “drift” of the zero point or the measuring value in the course of time is not allowed. Cross sensitivities, such as pressure or temperature variations must not influence the measurement results.
- Different installation sites : No two installation sites are alike and the possible installation sites often are very limited. Thus, the sensor must offer various mounting lengths or a sensor element that also allows a suboptimal orientation in the flow. Also the size of the sensor is important - the bigger it is the more limitation must be considered for the installation site.
- Wide flow measuring range : Due to the different operating conditions or duty cycles, the flow sensor must record minimum and maximum volume flows with maximum accuracy.
- Temperature recording : In flow measurement the temperature is another interesting measured variable and recording and evaluating it at the same time offers advantages.
