Annubar is one type of Flow element, i.e. primary element
for flow measurement. Some others are Flow Nozzles, pitot
tube,Ventury Tube,Aerofoil etc.)
Annubar basically measures DP (Differencial Pressure) and
has Diamond shaped sensor used for this.
In next generation , instead of diamond shape, an improved
Aerodynamic Bullet Shape flow element is available, it is
called Verabar. Advantage: Better accuracy, operating
range, signal stability and resistance to clogging.
