The main advantages in regard of other primary flow sensor as ventury tube and orifice plate are very characteristic.
DEBIX flow sensor can be used on all usual such liquids as water, petrol, oil or such gases as air, butane. Over heated or saturated steam flowrates can be measured to make energy balance.
The DEBIX probe allows measures in all kind of pipe such as carbon steal or concrete and all various forms (circular, square or rectangular).

Flow = f(√∆P) - Extension of Bernoulli theorem.

HP side: static P + dynamic P
Facing the flow, 4 ports are localised cutting the surface in 4 sections of equal flowrate. These 4 measured pressures are averaged and get added with static pressure into the pipe.
LP side: static P
Opposite flow, a 5th port get static pressure .
So, on the connection head, it is possible to get a differential pressure image of the flow as:
∆P = (HP - LP) = stat. P + dyn. P - stat. P = dyn. P
