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. 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. One should also take into consideration the cost of installation of the flow meter. 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 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. 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. Over its full range the flow meter’s performance may not be accepted unless one knows the measurement accuracy. The flow meters without moving parts one should choose over the ones with them when purchasing flow meters. Usually the flow meters with moving parts are a cause of problems and failure since the moving parts are prone to wear and tear. Clearance spaces for the moving parts that sometimes cause slippage into the flow being measured they also require. 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. For any waste liquids that are conductive, they are ideal. The displays are usually 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 frequency shift of an ultrasonic signal when it is reflected by discontinuities in the liquid flow is the principle of operation that is employed. The most used for liquids and gases on the other hand is the rotameter.Lessons Learned About Meters
