Definitions
- this system has a symmetrical configuration which allows first of all to simplify its insertion in the fluid flow line.
- this symmetry in the geometry of the flow member 1 implies that the measurement system is very insensitive to upstream and downstream conditions since the filter 4 has exactly the same effects in terms of pressure loss whatever the meaning considered fluid flow.
- the accuracy of the measuring system is therefore independent of the direction of the flow, which is particularly advantageous in certain application areas such as the automobile, for which certain flows, for example the flow at the intake of the engines thermal, can periodically change direction.
