FAQ

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.

What is the sonic condition?

The sonic condition is when a gas flows through an orifice and its pressure drops, a critical pressure value exists for which flow rate reaches the speed of sound in that gas. This happens when Pout/ Pin ratio is approx. 0.5. At sonic condition, flow rate and pout ... More
