FAQ

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 are primary flow elements?

Primary flow elements are built into piping systems and generate a defined differential pressure through a partial restriction in cross-section within the flow meter. The square root of this differential pressure is proportional to the flow rate.
