What is the beta ratio (β)?

The beta ratio (β) defines how strongly the pipe cross-section is restricted. The beta ratio should thus be considered as a factor. A beta ratio of 0.75 corresponds to a restriction of 75 % of the pipe cross-section.

What is the difference between differential pressure Δp and permanent pressure loss?

The differential pressure Δp is the differential pressure measured across the restriction, which is converted to a flow rate by a differential pressure transmitter (pressure drop inside the meter section). The difference between the upstream pressure and the ... More
