Abstract

The operating principles and mechanical construction of a micromanometer, which utilizes air in lieu of a liquid as working fluid, are described. Some of the noteworthy features of the instrument include its high sensitivity and accuracy, quick response, wide range, and ease of manipulation. Differential pressures of the order of 5 × 10−3 mm water gage can be measured with an error of 1 per cent under normal laboratory conditions. The maximum range of the prototype described is 25 mm water gage, and the corresponding error at this value amounts to about 0.25 per cent.
