Wind speedometer, air flow anemometer

What is an anemometer or air flow speedometer?

Anemometer is a tool to measure wind speed. The English name of this device is composed of the words anemos, which means wind, and meter, which means measuring. Anemometers can be divided into two general categories: 1- Wind speedometer 2- Wind pressure gauge. Although it should be noted that there is a direct relationship between wind speed and pressure. One of the simplest anemometer models is the cup model, which was invented long ago (in 1846 AD) and is made of four hemispheres that stand vertically on two perpendicular intersecting axes that rest on a rod. Among other examples of anemometers, we can mention the Asian model or windmill.

What is a wind speedometer or flowmeter?

A flowmeter is a device that can be used to measure the speed of moving air. We can also measure the air temperature that we are measuring through wind thermometers

The units of measurement of anemometers are feet per minute (ft/min), meters per second (m/s), kilometers per hour, miles per minute and Mach per hour, etc.

Anemometers can measure the speed of moving air through the rotating sensor they have, the blades of the vanes rotate freely to allow the air to flow, and as the air passes through the vanes, the blades move at the same speed. They come in and display the speed

What is CMM/CFM?

Cubic feet per minute (CFM) and cubic meters per minute (CMM) are units of air volume measurement. These expressions are the amount of air passing through a certain channel.

To do this, the area of ​​the air flow passage should be measured. This amount is in square feet or meters.

IR thermometer or laser thermometer installed on anemometers has many advantages, including:

Ability to calculate several parameters in one device

Avoiding wasting time and money

Checking hot spots in ducts, electrical panels and wired ducts

Use of anemometers:

Measuring air speed and temperature of ducts and channels

Air pressure testing in sensitive centers including calibration laboratories

· Testing the performance of vacuum cleaners such as hoods and reviewing them and analyzing their working conditions

Performance analysis of car engines

Monitoring the ionizing current output

Inspection of the ventilation system
