Another key point to comparing the different flow meters is that as long as the fluidic flow is a
continuous flow without pulsation, then the fluidic dynamic will have the system following the
Bernoulli equation:
where ρ is the fluid density; g is the acceleration due to gravity; P1 is the p
of the reference
meter; P2 is the pressure at the test meter; v1 is the velocity of the reference meter, and v2 is the
velocity of the test meter. h1 and h2 are the corresponding height for the meters which in most cases
is the same in the system. Therefore, it would be very critical to have the system not have a pressure
variation. (This explains our recommendations for the installations in Section 4). Also, the meter
measurement principle is often very important for the understanding of any discrepancies.
