Factors to Consider when Selecting a Flow Meter A flow meter is an instrument that is used to measure the flow rate of liquids or gases. When buying a flow meter one should take into consideration the familiarity of the working personnel with the device and their experience with calibration. The maintenance factors such as availability of spare parts and the probability of failure are some factors one should put into consideration. The cost of installation one should also take into consideration. One should not buy a device because it is less expensive since this can be the most costly installations. An installation engineer one can consult when buying the flow meters just in case there are any flow measurement challenges. The best flow meters basics of selecting are evaluating the nature of the process fluid and the fluid and flow characteristics. One should also consider the piping and the area the flow meter is to be located. The characteristics of the fluid to be considered are the pressure, temperature, viscosity, density and many others. Of how they should interact these properties should have an indication for the flow meter to operate properly. Also there should be a detailed composition of the fluid. This is to say that one should indicate whether the fluid has solids and whether they are soft or abrasive or whether they have big or small particles. One should know the required meter range so that they can select the best meter and this is done by identifying the minimum and maximum flows that will have to be measured. Over its full range the flow meter’s performance may not be accepted unless one knows the measurement accuracy. When one is purchasing a flow meter they should choose the ones without moving parts over the ones with them. A cause of problems and failure are the flow meters with moving parts since they are prone to wear and tear. They also require clearance spaces for the moving parts that sometimes cause slippage into the flow being measured. There are different types of flow meters which include; rotameters, piston flow meters, paddlewheel, turbine flow meters, ultrasonic flow meters and magnetic flow meters. For in-line or insertion types the magnetic flow meters are available. For any waste liquids that are conductive, they are ideal. Usually the displays are integral and an analog output can be used or remote monitoring. For dirty water or waste water the ultrasonic flow meters are also used. The principle of operation employs the frequency shift of an ultrasonic signal when it is reflected by discontinuities in the liquid flow. The most used for liquids and gases on the other hand is the rotameter.Case Study: My Experience With Resources
