What is an Ultrasonic Gas Flow Meter?
While it seems like a simple question, an ultrasonic gas flow meter is a very complicated piece of equipment. These devices are used to measure the flow of gases and fluids through a pipe. While some are fixed, they also come in an ultrasonic flow meter portable version. These units are great for getting a quick reading and are almost as accurate as the fixed version.
Features and Functions of a Ultrasonic Gas Flow Meter
The units are generally non intrusive so that they will not affect the flow running through the pipe being measured. There are several different methods for measuring flow from transit time correlation to concurrent transit time, pulsed Doppler and continuous wave Doppler. Not all applications are the same and it is important to be able to offer flow meters that suit the actual requirements. The use of non intrusive measuring devices has increased in popularity over the last ten years saving valuable time and in addition preventing the contamination of surrounding areas.
The ultrasonic gas flow meter is incredibly sensitive piece of equipment and a good one will be able to tell within a very fine area how much gas is flowing. These clamp on ultrasonic gas flow meters can measure the erosive, corrosive, toxic, high purity sterile gases or any application where penetrating the pipe wall is undesirable. Theses meters generally will have a wide range and the meters will have no wetted or moving parts for virtually no maintenance. A clamp on ultrasonic gas flow meter will not cause any drop in pressure, as it resides outside the pipe.
For the most part meters will also offer the option to export there readings directly to a computer. This can be done through any number of auxiliary inputs and is useful to monitor and compare data from multiple ultrasonic gas flow meters.
As you can see a gas flow meter is much more complicated than it would first appear. They come in a variety of forms and can be used in a variety of applications. It is up to you the user to decide what the best application for your ultrasonic gas flow meter is, and which one will best fit.
Whether it is a fixed or portable unit, whether it measures multiple values simultaneously or simply does individual ones is up to you. The important thing is that these devices no longer need to be placed inside the pipe and you can safely and reliable measure the flow with no harm to the outlying areas.
