Using a pitot tube to measure air velocity

USING A PITOT TUBE TO MEASURE AIR VELOCITY HOW TO

The advantage of this method is that it is easy to set up without disturbing the process. The basic construction of the Pitot Tube showing the Impact pressure and the Static pressure port О”P = The differential pressure (Pa, psi) measured by the pressure sensor which is the Velocity Pressure (Impact pressure вЂ“ Static Pressure) To simplify the calculation, below is the simplified formula to calculate the velocity of the air in a duct which is related to differential pressure: These pressures are the Impact pressure and the Static pressure (see photo below). In simple terms, we can calculate the velocity of the fluid (air) inside a duct or channel by determining the differential pressure.

The basis of measurement is through the use of BernoulliвЂ™s principle. It has the same application but with a different method and approach of measurement.ДЄ pitot tube is used to measure the velocity of air in a duct with just a small opening. If you are familiar with the vane anemometer, then you can relate to this easily. The Pitot Tube вЂ“ Where to use a Pitot Tube Anemometer This instrument is the Extech HD350 Pitot Tube Anemometer

This type of instrument is still new to me, but I wanted to share with you to be familiar with a pitot tube and it will also give you some ideas on how to use it. Using A Pitot Tube Anemometer to calibrate the volume flow transmitter used in the duct.How to verify the velocity and airflow in a duct using a Pitot Tube Anemometer.The basic principle of the Pitot Tube Anemometer.In this post, I will share with you the following: We just need a small opening anywhere in the duct or pipe to insert the Pitot tube. A simple placement of the vane (fan) in front of the opening of the duct directly measures the wind velocity or volume flow.Д«ut what if the opening or the output end of the duct is not accessible? It is here where we can use the Pitot Tube Anemometer.

Measuring or verifying the airflow coming out from the output end of the duct is very simple, an easy way is to use a vane anemometer.
