Flow measurement at high temperature and pressure
The measurement of the flow velocity and/or the volume flow at
higher temperatures up to +350 °C is very important in many fields
with regard to energy efficiency, quantity detection and system control.
The requirements of the stationary flow sensor are very high.
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
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
Due to the different operating conditions or duty cycles, the flow
sensor must record minimum and maximum volume flows with
In flow measurement the temperature is another interesting measured
variable and recording and evaluating it at the same time offers
