The availability of many flow technology options makes people to consider selecting the flow meter for an application as a bewildering task. There are many factors that they need to consider while choosing the flow meter. A wide array of factors are there influencing the selection of flow meter and cost is one of the factors. Most of the users just like to know the rate of gas or liquid moving through the pipe. In these cases, a flow indicator distributed by a flow meter vendor at the fraction of the price of simple flow meter will suffice. These are easy and simple to install and need no external power. People can use these instruments to offer local flow indication. Even where there are demands for something that is more sophisticated like a flow indication to within 10 percent, there may occur no need of buying a flow meter. Many of the installations feature joints or bends that can get converted into crude flow meter by buying differential pressure transmitter, installing the sensors and measure the variation in pressure between many points.
When people have decided to buy a flow meter they do not consider buying the cheap one. Even though it seems the best idea to save their money, going with the lowest price solution can result in some problems. They should stay careful where the reductions in purchase price are achieved by cuts in expertise and supplier back up. The cost-effective installations are the one where the vendors can offer better technical back up support. The last thing they need to consider while choosing the flow meter is how the gas or fluid behaves when it flows through the pipeline. By knowing how it behaves, they can narrow down their choice and buy the best flow meter for their application.
