You may have heard of a peak flow meter if you have Asthma and wonder is it really worth it. How do you use it? What good is it really? Well it turns out that it's often hard to tell how strong your breathing is at any given moment. There are so many other things going on in your life - if you're tired, if you're feeling happy, if you're feeling down. And you may think you know how tight your airways are, but often people don't. I'm Dr. Alan Greene and I want to explain to you how powerful it can be to have real numbers telling you how well you're breathing. If you've got accurate numbers and you keep them day after day, you can use that to adjust your medicines. That means you can use the lowest amount of medicine possible to feel the best possible.
So here's how they work. Usually there's a mouthpiece. You just screw into one end so you can keep it clean. And there's a little gauge here that reads the numbers and you move it all the way down to 0. Then just seal your mouth around the mouthpiece and blow hard, as hard as you can once. (Blow sound) Made it almost to the end. Scored pretty well. Then what you do is write down that number. Pull it back to the beginning and do it a total of 3 times. Whatever the highest number is, that's how well you're breathing right now. Then you can compare it that your asthma action plan. That number will either fall in the green zone, or the yellow zone, or the red zone. And it will help you know exactly what to do to best control your asthma with the minimal amount of medications. Really, really worth it.

Depends on what type of flow meter your inquiring about. Almost all cases point to yes. Here is a site that will help you if your inquiring about a specific one that i cannot answear for all of http://www.flowmeterfacts.com/.
Move the marker to the bottom of the numbered scale.Stand up straight.Take a deep breath. Fill your lungs all the way.Hold your breath while you place the mouthpiece in your mouth, between your teeth. Close your lips around it. Do not put your tongue inside the hole.Blow out as hard and fast as you can in a single blow. Your first burst of air is the most important, so blowing for a longer time will not affect your result.Write down the number you get. If you coughed or did not do the steps right, do not write down the number. Do it over again.Move the marker back to the bottom and repeat these steps 2 more times. The highest of the 3 numbers is your peak flow number. Write it down in your results log.Reviewed ByReview Date: 03/10/2009David C.

An electromagnetic flow meter is a flowmeter which uses the electromagnetic technology to determine the amount of volume flow though a pipe. View the Related Links section for a link with a video about this.
Flow in a venturi meter refers to the rate at which a fluid passes through the device. The flow of fluid is measured by the pressure difference created between the converging and diverging sections of the venturi meter. This pressure difference is directly related to the flow rate of the fluid passing through the venturi meter.
Averaging peak expiratory flow rate readings is not recommended because it may mask fluctuations that could be important for diagnosing and managing conditions such as asthma. It is more beneficial to monitor the peak flow variability to better understand how the condition is progressing and to tailor treatment accordingly. Individual peak flow readings can provide valuable insights into a person's respiratory health that may be obscured by averaging.
because that is what the peak flow meter reads after you have blown into it

A peak flow meter is used to measure the maximum speed at which air can be exhaled from the lungs. It is commonly used to monitor and manage conditions such as asthma and other respiratory problems.
To monitor a one's ability to breathe out air.
There is no specific amount of air that confirms asthma, but if your peak flow reading is consistently below 80% of your personal best, it may indicate asthma or poor control. Readings below 50% suggest a medical emergency. Always consult a doctor for proper diagnosis.

it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.

Peak flow meters can range in price from around $15 to $60, depending on the brand and features included. You can find them for purchase at most pharmacies or medical supply stores.
te average for a 14-15 year old on a peak flow meter is 800.
