Ways of Selecting a Flow Meter The flow rate of liquids and gases is measured by the use of an instrument that is known as a flow meter. One should take into consideration the familiarity of the working personnel with the device and their experience with calibration when buying a flow meter. 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. A device because it is less expensive one should not buy 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 basics to selecting the best flow meters 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 pressure, temperature, viscosity, density and many others are the fluid characteristics to be considered. For the flow meter to operate properly these properties should have an indication of how they should interact. There should also be a detailed composition of the fluid. Whether the fluid has solids and whether they are soft or abrasive or whether they have big or small particles this is to say that one should indicate. One should know the required meter range and this is done by identifying the minimum and maximum flows that will have to be measured so that one can select the best meter. 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. Since the moving parts are prone to wear and tear, usually the flow meters with moving parts are a cause of problems and failure. They also require clearance spaces for the moving parts that sometimes cause slippage into the flow being measured. Included in the different types of flow meters which are there are; 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. They are ideal for any waste liquids that are conductive. Usually the displays are integral and an analog output can be used or remote monitoring. The ultrasonic flow meters are also used for dirty water or waste water. The principle of operation employs the frequency shift of an ultrasonic signal when it is reflected by discontinuities in the liquid flow. The rotameter on the other hand is the most used for liquids and gases.Lessons Learned About Meters
