How To Fill Glass Barometer?

How to fill the weatherglass: Hold spout under tap and fill with a thin stream of water. The water level of the bottle itself should be approximately one inch (2.5cm) above the place where the spout joins the bottle. If used outdoors fill with rubbing alcohol during winter to avoid freezing.

How does a glass barometer work?

The principle is that the air left in the bottle above the water exerts the pressure of the air at the time the bottle was filled while the liquid in the spout is exposed to the changing atmospheric pressure. As the atmospheric pressure falls the water in the spout rises and vice versa.

What is the liquid inside a barometer?

Though other liquids can be used in a barometer mercury is the most common. Its density allows the vertical column of the barometer to be of manageable size.

How do you read a glass fluid barometer?

What pressure should I set my barometer?

To convert from hPa on the Met Office website to inches you will have to divide by 33.86. So for example if the Met Office observation shows 1013 hPa then you should set your barometer to 1013/33.86 = 29.92 inches or as close as possible to this.

How do you tell if a barometer is working?

Hold the instrument at the 45-degree angle and check the the level of the mercury in the glass tube with a long “stick” barometer. If the barometer is working correctly the mercury inside will rise quickly to fill the very tip of the tube leaving no air bubble.
