How to Select 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. One should not buy a device because it is less expensive 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. The piping and the area the flow meter is to be located one should also consider. 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. 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. The flow meter’s performance may not be accepted over its full range unless one knows the measurement accuracy. The flow meters without moving parts one should choose over the ones with them when purchasing flow meters. Since the moving parts are prone to wear and tear, usually the flow meters with moving parts are a cause of problems and failure. Clearance spaces for the moving parts that sometimes cause slippage into the flow being measured they also require. Different types of flow meters are there and they 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 integral the displays are and an analog output can be used or remote monitoring. Also the ultrasonic flow meters are 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 most used for liquids and gases on the other hand is the rotameter.Lessons Learned About Meters
