How I Became An Expert on Equipment

Ways of Selecting 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. Also one should take into consideration the cost of installation of the flow meter. Because a device is less expensive one should not buy it since this can be the most costly installation. An installation engineer one can consult when buying the flow meters just in case there are any flow measurement challenges. Evaluating the nature of the process fluid and flow characteristics are the basics to selecting the best flow meters. Also, one should consider the piping and the area the flow meter is to be located. The fluid characteristics 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. A detailed composition of the fluid should also be there. 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 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. 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. 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. 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. 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. Also the ultrasonic flow meters are 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. On the other hand the rotameter is the most used for liquids and gases.Lessons Learned About Meters
