Yes, a barometer can be used below sea level to measure atmospheric pressure. However, the reading may be slightly affected by the pressure of the water above it, which needs to be accounted for to obtain an accurate measurement.
Positive integers can represent elevations above sea level, while negative integers can represent elevations below sea level. For example, an elevation of 500 meters above sea level can be represented by the integer +500, while an elevation of -200 meters below sea level can be represented by the integer -200.
Standard atmospheric pressure at sea level is taken as 1 atmosphere for all intensive purposes. Atmospheric pressure near to the surface of the earth is about 1 atm. If we go above it decreases and increases we move towards the center of the earth.
The simple answer is zero feet elevation, but first of all, it is almost impossible to tell that you are at the exact sea level that is the average of all the different sea levels caused by all the different tide elevations. That is why GPS and surveying do not much use "mean sea level", anymore. These days "zero elevation" is determined by the strength of the field of gravity as calculated and measured all around the world.
Meteorologists use a barometer to measure air pressure. A barometer can be either an aneroid or a mercury type and helps meteorologists predict changes in the weather based on differences in air pressure.
No, a barometer does not use a bimetallic strip. A barometer measures atmospheric pressure, usually using a column of mercury in a glass tube. A bimetallic strip is typically used in devices to measure temperature, as it bends with changes in temperature due to its two bonded metal strips with different coefficients of thermal expansion.

To calculate altitude accurately and efficiently, you can use a barometer or GPS device. The barometer measures air pressure, which decreases as altitude increases. By comparing the air pressure to a standard pressure at sea level, you can determine altitude. GPS devices use satellites to determine your exact location, including altitude. This method is accurate and doesn't rely on weather conditions like a barometer.

Use positive numbers for altitudes above sea level, zero is sea level itself, and negative numbers for altitudes below sea level. As for the picture, use a number line - but make vertical instead of using the commonly used horizontal position.
