14.5 Performance characteristics
Max. measured error
Accuracy Accuracy of concentration measurement
The measuring device can achieve an accuracy of up to 0.01%. The accuracy depends on the
concentration app. The data sheet for the concentration app contains detailed accuracy
information under the "Approximation error" section.
Measuring frequencies
Response time
The response time for displaying the temperature depends on the transfer of heat from the
fluid to the steel.
Influence of variations in
the fluid temperature
If the fluid temperature changes quickly (>1.5 °C/min), the meter displays a error message.
Influence of vibrations The meter displays a error message as a result of mechanical or acoustic vibrations in the 0.8
to 2.0 MHz range.
Influence of air bubbles Air bubbles and particles are disturbance factors when measuring with acoustic surface
waves. The diagnostic functions integrated in the measuring device largely prevent an incor-
rect measurement result due to air bubbles or particles.
