How do I read a wheel barometer?

The main circular dial shows atmospheric pressure measured in inches of mercury, pointing toward indicators like 'Stormy', 'Rain', 'Change', 'Fair', and 'Very Dry'. A secondary pointer, adjusted by a brass knob on the glass bezel, is set over the primary needle to track daily changes. Rising pressures indicate improving weather, while falling readings suggest approaching rain or wind. The smaller spirit level at the very bottom ensures the entire instrument hangs straight so the internal weights move freely.

Were these barometers meant for walls?

Every example of this form was designed strictly for vertical wall hanging rather than freestanding placement. The long wooden trunk provided the necessary drop for the internal mercury cistern and siphon tube. Placing them away from direct sunlight, radiators, and heavy foot traffic protected both the delicate mahogany veneer and the sensitive glass tubes inside.

Are these barometers still accurate?

Many surviving examples remain fully functional when serviced and correctly levelled on a sturdy wall. The mercury columns respond naturally to shifting barometric pressure systems in the surrounding room. Transit can occasionally disturb the mercury column, requiring careful handling or professional resetting before accurate readings resume.
