An introduction of gas flowmeter
A gas flowmeter is a device used to measure the flow rate of gaseous substances. By the name itself, it shows that the device can be carried anywhere. It does not need to be connected to an electrical output. It is therefore handy. However, using this kind of device is quite tricky so read on to know more about how it works.
The device uses two transducers that are placed on the pipe at a one foot distance, although the distance may vary for some kind of gas flowmeters. When the transducers are set in their approximate distances, make a ring on one of the transducers.
Wait for a while then you can do the test for the second time and so on. The test can be done continuously to get a good observation on how the pipe runs in a certain period of time.
However, you have to know the things that may affect the results of the test. These should be considered to avoid further negative results. One factor that should be looked upon before performing the test is the transparency of the stream.
A cleaner stream will not have any problems with portable flow meter. If the gas flowmeter is contaminated, the result may be inaccurate.
The diameter of the pipe that is tested also affects the result of the measurement. There are specific flow gauges for pipes of different sizes. When testing pipes using flow meters, be sure that you are holding on to the appropriate unit size or the whole measuring thing is ruined.
Exact fitting of the flow meter to the pipe is needed. When you measure for flow rates, make sure the test is done not only once but in a number of times.
This is to ensure a smaller number of errors and to compare for any differences when there are other factor that have been affecting the entire performance. Better results will be obtained when there are more readings. This is because of the varied speed, temperature, or pressure of the gas being measured.
