PORTABLE DIFFERENTIAL PRESSURE GENERATOR

摘要

A portable pressure differential generating system having a portable flow accelerator (100) having with a high pressure region (110) with a first cross sectional area and a low pressure region (106) with a second cross sectional area, the first cross sectional area being larger than the second cross sectional area. The accelerator (100) further includes an accelerator low-pressure tap (104) in fluid connection with the low-pressure region (106) of the flow accelerator, the low-pressure tap (104) is adapted for fluid connection with a low-pressure port of a pressure-measuring device. The accelerator further includes an accelerator high-pressure tap (108) in fluid connection with the high-pressure region (110) of the flow accelerator (100), the high-pressure tap adapted for fluid connection with a high pressure port of a pressure measuring device. The system includes a portable pump (124) in fluid connection with the passage in the flow accelerator (100).
