Abstract
Flow straightener for improving the flow profile in a gas line ahead of a flowmeter, comprising at least three plates with regularly distributed perforations and spaced apart parallel to each other perpendicularly to the axis of the line. The perforated plates are mounted with a circumferential sealing (preferably welded) in or on a sleeve which can be inserted in the line with a sliding fit.
Claims2
A device for improving the flow profile in a gas line ahead of a flow meter, the said device comprising three plates with regularly distributed perforations, said plates being spaced apart parallel to each other at a distance approximately equal to half of the internal diameter of said line and disposed perpendicular to the axis of the line, said perforated plates being mounted in said line with a circumferential sealing in or on a sleeve which can be inserted in said line with a sliding fit, with the total surface area of the perforations in each separate plate equaling 15-25% of the ree sectional area of said line.
