Manometer
Seismometer was created in 1880.
Manometer
When mercury is used a manometer fluid and the manometer tube is inverted it will measure the small pressure difference in liquids. This is a tool used by scientists.
Not quite; This is what the first source said about how a thermometer works; This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. In other words, the thermometer goes up or down due to the expansion of the alcohol or mercury due to the heat. After reviewing the second source, you will see that the columns go up and down due to the atmospheric pressure. If it goes up and down due to atmospheric pressure it is a manometer. A manometer does not work if it is not exposed to the atmosphere. A thermometer is sealed off to the outside. This is another reason why a thermometer is different from a manometer.
A barometer measures atmospheric pressure, while a manometer measures the pressure of gases or liquids in a closed system.

the most common type of manometer are u-tube type,inclined and the cistern type of manometer
To set up a manometer, first ensure that it is securely mounted in a vertical position. Fill the manometer with a fluid, typically mercury or water, making sure there are no air bubbles. Connect the manometer to the system you want to measure the pressure of, and then observe the height difference of the fluid levels in the manometer to determine the pressure.

A 2005 Dodge Caravan does not have a manometer.
Electrical manometer is an electronic manometer use to record pressures between two points. It is commonly used in recording pressure in bridges.
A manometer is used to measure pressure. A well-type manometer measures a singular height of pressure and is normally highly accurate.
