Title:
PORTABLE DEVICE FOR IN-SITU MEASUREMENT OF ACTIVE PRESSURE
Document Type and Number:
WIPO Patent Application WO/1998/023927
Kind Code:
A1
Abstract:
The disclosed portable device for measuring active pressure is set in the path of a liquid flow. The device is comprised of a body (1) through which the flow runs, wherein said body comprises a measuring channel (2) in the form of a diffuser, a converging tube and a diffuser combined together. The cross-sectional areas at the entry (3) and exit points (4) are identical. A large differentil $g(D)P is obtained between the pressure values P�max? and P�min? at the points of maximum (5) and minimum (6) sections, thereby ensuring highly accurate measurements.
