Ultrasonic Signals Used in Portable Gas Flow Meters
By [http://ezinearticles.com/?expert=Gottlieb_Wendehals]Gottlieb Wendehals

Have you ever needed to test the flow rate of a fluid, but there was no flow meter installed? At times like that, a portable flow meter is extremely useful. A portable flow meter can still measure the flow rate of a fluid with accuracy, but is portable, so one can move it around and test multiple locations. They are made portable because the transducers small and light enough to hold in one hand. Ultrasonic signals in gas flow meters are used because they are non-invasive, that is they do not touch the fluid being measured. They are created to be able to measure many types of fluids, such as oxygen, steam, or diesel. This article will explain the usefulness of a portable ultrasonic gas flow meter.

Portable ultrasonic gas flow meters are usually light enough for someone to hold in one hand. This allows for easy transportation, and easy measurements of multiple locations. The main reason why they are light weight is because the transducers are made to be as light and small as possible. Even though they are portable, that does not mean that quality is lost in measurement. A portable flow meter can be as accurate as it is portable.

All portable flow meters are non-invasive. This is because it would need to work with multiple fluids, otherwise being portable would not do any good. Typically a portable flow meter will use ultrasonic because it does not interfere with most fluids. Ultrasonic is also a very useful because it is easy to produce and to measure with, and it works on simple echolocation or Doppler principles.

Because ultrasonic waves do not interfere with many fluids, it can be used with multiple types of fluids. Examples include oxygen, steam, diesel, or just plain normal or compressed air. As long as the fluid is within the technical specifications, a portable ultrasonic gas flow meter can be used for it.

Portable ultrasonic flow meters are very useful for people who use machinery that use a type of fluid for normal operation. Even if a person forgot to buy a non-portable flow meter, a portable flow meter is a suitable substitute until he or she can get a non-portable one. Most portable flow meters use ultrasonic signals, though some can use electromagnetic signals. Ultrasonic waves typically do not cause interference in the fluid's rate of flow and can provide very accurate readings. A portable ultrasonic flow meter is usually small enough to carry around with one hand, so they are easy to transport as well as use. If you do not have a portable ultrasonic flow meter, and use machinery that uses fluids, then get one today!
