Ways of Selecting a Flow Meter An instrument that is used to measure the flow rate of liquids and gases is a flow meter. When buying a flow meter one should take into consideration the familiarity of the working personnel with the device and their experience with calibration. 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 best flow meters basics of selecting are evaluating the nature of the process fluid and the fluid and flow characteristics. Also, one should 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. These properties should have an indication of how they should interact 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. So that one can select the best meter they should know the required meter range and this is done by identifying the minimum and maximum flows that will have to be measured. The flow meter’s performance may not be accepted over its full range 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. Usually the flow meters with moving parts are a cause of problems and failure since the moving parts are prone to wear and tear. Also they 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. The magnetic flow meters are available for in-line or insertion type. 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 frequency shift of an ultrasonic signal when it is reflected by discontinuities in the liquid flow is the principle of operation that is employed. On the other hand the rotameter is the most used for liquids and gases.A Simple Plan: Equipment
