How to Select a Flow Meter A flow meter is an instrument that is used to measure the flow rate of liquids or gases. One should take into consideration the familiarity of the working personnel with the device and their experience with calibration when buying a flow meter. One should also consider the maintenance factors such as availability of spare parts and the probability of failure. 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. When buying the flow meters one can consult an installation engineer 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. The piping and the area the flow meter is to be located one should also consider. The pressure, temperature, viscosity, density and many others are the fluid characteristics to be considered. Of how they should interact these properties should have an indication for the flow meter to operate properly. A detailed composition of the fluid should also be there. That one should indicate whether the fluid has solids and whether they are soft or abrasive or whether they have small or big particles this is to say. 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. Unless one knows the measurement accuracy, the flow meter’s performance may not be accepted over its full range. 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. The magnetic flow meters are available for in-line or insertion type. 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. Employed by the principle of operation is 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
