Abstract
We have perfected a very sensitive, high-resolution electronic flow-meter. The module we have been working on has a cut-off frequency of 200 Hz. It works in a range of pressure-difference from 1 to 100 pascals, with a resolution of 0.1 pascal. The device has enabled us to carry out a series of ground measurements tests of the air's dynamic pressure and of the structure ratio of this parameter, as well as differential pressure measurements. Used as a very sensitive variometer, it has permitted measurements in altitude by means of a meteorological plane specially equipped for turbulence measurements. It can also be operational in a captive balloon or in a glider.
