Influence of direction

The correct design of the shape of the sensor head decisively
flow
probe
influences the accuracy of the flow measurement. This is particu-
larly true for correct measurement when the sensor is rotated on or
along its longitudinal axis, away from the prescribed direction of
flow onto the sensor.
The VELOPORT 20 sensors have excellent characteristics in this
respect and demonstrate relatively small angle dependence.
The measurement error in the range from +/- 15° is less than 3% of
the measurement value.
