Abstract. WHILE a barometer of the Fortin pattern is generally regarded as a better laboratory instrument than one of the Kew pattern, many observers prefer the latter, owing to the difficulty Background. A barometer is a type of manometer.A document on manometers may be accessed by clicking on the blue button to the right; it will appear in a separate window.. Y ou will also need to know how to read a vernier scale.A document on this may be accessed by clicking on the green button to the right; it too will appear in a separate window. A Fortin barometer is usually also provided with a gimbal mount to that it may be maintained vertical. This, of course, is especially important in marine instruments. Restoring the Vacuum in a Fortin Barometer. The quality of the Torricellian vacuum is the most important factor controlling the accuracy of a Fortin Barometer.

Mercury is contained in a leather bag at the base of the mercury reservoir, and height, H, of the mercury in the reservoir can be adjusted using the screw at the base of the barometer to depress or relase the leather bag.To measure the atmospheric pressure, the screw is adjusted until the pointer at H is just touching the surface of the mercury Look up a route map or download weekly timetables for any train, bus, ferry, light rail or coach service.

Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries..
