A flow meter is an important piece of equipment in various industries. The device measures the mass flow rate or volume of fluid that passes through a pipe. Flow meters can be used for liquids such as water or gases such as air. You must choose the suitable model for your needs.
We’ve put together a list of some things to keep in mind when looking for a flow meter:
Size-Flow meters are available in varying sizes, ranging from miniature models meant for single point-of-use applications to large models designed to monitor entire industrial pipelines. Knowing the intended use of your flow meter will help you decide which model will suit you best.
Viscosity– The viscosity can be too high or low for some meters. Also, certain viscosities can require a multi-stage turbine meter. Some meters are better on certain fluids than others. For example, an ultrasonic meter-see the 2nd generation here works best on fluids with high levels of dissolved solids and suspended particulates. Furthermore, a magnetostrictive meter works well for liquids with low dissolved solids and particulate levels.
Type of fluid-The type of fluid being monitored can also influence the type of flow meter used. For example, you can choose between volumetric or gravimetric flow meters depending on the type of fluid being measured. A volumetric flow meter will give you an accurate reading if your fluid has a constant density, while a gravimetric flow meter will give you an accurate reading regardless of density.
Calibration procedures-Flow meters must be calibrated before use, so it’s crucial to find out what calibration procedures are necessary for the model you’re considering buying. Some models require that you recalibrate every time, but some feature automatic calibration modes activated whenever a new sensor is attached to the device, making it easy and convenient to recalibrate at any time.
Accuracy– Inaccurate flow readings can result in inaccurate product measurements and may cause your business to lose money. Your flow meter should be able to consistently produce accurate readings within 0.1% of the actual volume, no matter what type of liquid you are measuring or the speed that the liquid is moving through your piping. In addition, you should invest in a flow meter that can be recalibrated if necessary. Some flow meters cannot be recalibrated, which means that if you notice inaccuracy within your measurements, you will have no way to adjust.
Durability– Durability is an essential factor when choosing a flow meter. Consider the cost of the flow meter and how long it should last. You are not recommended to purchase a flow meter with a short shelf life. This will cause problems later on when the device fails, which means you will have to purchase another one, which can be costly.
Ease of use– Ease of use is very important in a flow meter, as it will determine how comfortable the user feels when using it. If a flow meter is easy to use, the user will feel confident and less stressed when using the device. Also, if the user feels confident in the flow meter, they are more likely to use it correctly.
Pressure- Pressure is a crucial factor when choosing a flow meter. In many applications, the accuracy of the measurement is defined by the accuracy of the pressure sensor that is used to obtain the flow rate. The pressure sensor must measure both positive and negative pressures.
Finally, flow meters are used to measure and manage flow rates of fluids moving through various applications, from water, gas, oil, or steam. Flow meters have changed over the years, with digital sensors and advanced electronics being used instead of mechanical ones.
