Abstract

A pressure-measuring device is described which combines the principles of a hypsometer and a mercury barometer. It provides the accuracy and stability of the latterthe sensitivity of an aneroid device, and the mechanical simplicity and ease of telemetry of a hypsometer. This instrument appears ideally suited for use in automatic weather stations or installations where remote readout is required.
