The aerometer is an instrument used in industry to measure the concentrations of substances. They are used in the food industry in order to ensure market production. It guarantees the reduction of time in food production and the reliability of the quality of the finished product.

What is the Aerometer?

The definition of aerometer comes from the Greek “Aero” which means air and “meter” which is measure. So aerometer means the measurement of air. Measure the physical properties of air or other gases. It is designed to perform the measurement of the density of air and gases mostly. It is used to determine the density.

The flow, the concentration of air or a certain gas. It measures the specific weights, the relative density of liquids and the concentrations of solutions. They are instruments that float on the surface of liquid or gas. It is also known by the name of densimeter. It is a simple instrument that works based on the Archimedes principle.

Features of aerometer

The aerometer

It refers only to the device taking into account that they have a varied size, they are small and transparent. Its shape is cylindrical, hollow with a circular end. It is made of thick glass. Pose a scion shaped like a flat sphere. With a small amount of mercury in its background. It has a rod with some measurements for grading the instrument,

Types and divisions

In the market there is different variety of aerometer. Hall's.1. Hutchinson's.3.The JPEG. From Frokjaer-jensen.910. Smith's.78. The Struve. 45. The Scheurer.  They are divided into: constant volume and variable weight, where the instrument is immersed in the gag or liquid for one minute, letting out a constant volume to make the measurement.

Of variable volume and constant weight, the device is introduced at different depths according to the density of the liquid or gas, a variable volume of liquid or gas is allowed to dislodge from the apparatus. The instruments used to perform the measurement are Baumé, Cartier. Of variable volume and variable weight, the appliance is submerged allowing gas or liquid to escape in different quantities.

varying its weight according to the bodies whose density it determines. The most used instruments in this measurement is Rousseau's, Paquet's.

Aerometer how it works according to the scale

Making reference to the aerometer of variable volume and constant weight, according to how the instrument is graduated. In those that use arbitrary scale (Baumé, it is different taking into account what liquid it will be used for, Cartier). measurements at first gives out the degrees of concentration, a second measurement is necessary.

Use the conversion measures to get the result. The special scale of (Gay-Lussac). Use the one for volume and density. The Baumé aerometer has a wide variety of application. Used in liquid substances with low density with reference to water. The names are usually: The most acidic, they take into account the number of degrees from 0° to 70°.

It weighs syrups, with degrees from 0° to 40°, weighs salts from 0° to 45° and weighs milk from 0° to 15°. The low density reference with respect to water is that of ethers.

Use of the Aerometer

It is used in many areas of research to determine the purity, density of a substance or a gas. It is used for the quality control of a mass-distributed product such as the sector power. It also performs the measurements to substances with densities pre-established. Widely used in physics and chemistry in investigations of analysis of a sample.

How is the aerometer used?

What must be done is to insert a quantity of the sample into a graduated cylinder. Proceed to shake the sample with a glass rod to equalize the density and temperature of the sample. Select the appropriate aerometer, which is clean, whose measurement scale is above that of the sample to be determined.

Proceed to introduce the instrument into the liquid gently, without touching the walls of the container. So that it does not sink or break at the bottom. Give a lapse of time for the aerometer to balance. The realization of the reading is based on the meniscus. The temperature is checked and corrected.

So far I brought you information about the aerometer, I hope you have understood and served. Remember you can review it whenever you are interested.
