Total water content instrument

摘要

An instrument for sampling both solid and liquid water particles in the atmosphere and continuously producing an electrical output response directly equivalent to the total percentage water content of the atmosphere sampled. The solid and/or liquid water particles are collected by using a large funnel shaped scoop of 100 cm2 to allow high volume collection at nominal aircraft speeds. The water is routed into the detection device which includes a concentric cylinder flow-through capacitor that varies in capacitance according to the dielectric of the fluid enclosed.
