5 Considerations When Selecting a Flow Meter
Whether you are doing the flow meter selection in-house or a vendor or contractor selection of flow meters doing the selection for you, there are many factors you need to consider to successfully see this process through.
To select the right flow sensor or meter, you need to consider many important factors: The basis of a good flow meter selection is a clear and thorough understanding of the requirements of the particular application that the flow sensor is intended for.
Some of these application requirements include: If remotely, should the transmission be analog, digital or shared. If shared, what is the minimum data update rate or frequency.
Many users often just want to know the rate at which a liquid or gas is moving selection of flow meters a pipeline.
In such cases, a simple flow indicator, available from any flowmeter vendor at a fraction of the cost of the simplest flowmeter, will selection of flow meters suffice. Simple and easy to install and requiring no external power, these instruments can be used to provide local indication of flow.
Flowmeter Selection Guide
Many installations typically feature bends or joints that can be readily converted into a crude flowmeter by purchasing a differential pressure transmitter and installing sensors to measure the difference in pressure between two or more points. Although it might seem the best way to save money in the short term, opting for the lowest cost solution may potentially result in problems later down the line.
Be particularly careful where reductions in the purchase price have been achieved by cuts in supplier back-up and expertise. Ultimately, the most cost-effective selection of flow meters will be the one where the supplier can offer good technical back-up, independently traceable test facilities, an established track record and a reputation for high-reliability products based on sound research and development.

Most of the information available on the web is useful, although some misinformation is available.
Selecting A Flowmeter
Contact Several Possible Suppliers Some companies will simply market their flow metersbut some organizations will have discussion and consultation with selection of flow meters to provide an optimal flow meter to meet their project and financial objectives.
It is advised to use a reliable supplier with a proven quality system and an internationally recognized, traceable calibration system in order to get a high level of after care service and knowledgeable support. Compare Technologies Pragmatically After purchase, several technological solutions will usually be offered to that particular flow metering application.
Users must consider each solution carefully. The comparison of proposed technological solutions helps users to match a flow meter to their operating parameters, ease of use, its cost of ownership and the level of support it may need.
HOW TO SELECT A FLOW METER | Flow Knowledge | KEYENCE America
Technologies such as electromagnetic, Coriolis, ultrasonic, and thermal flow material are viable options to measure a bespoke selection of flow meters at low flow rates. Better accuracy can be obtained with Coriolis but at a higher cost. Electromagnetic may be a suitable solution but is dependent on the conductivity of the fluid.
Thermal is characterized by slow response time and poor accuracy. Ultrasonic is an ideal solution in terms of price, user-friendly operation, and performance for most applications, especially applications involving low flow.
The charts shown in Figure 3 present the key features of different types of flow metersof which a perfect flow meter would be a completely solid filled pentangle.
Top Tips for flowmeter selection
What about the pressure selection of flow meters temperature of the fluids and gas - how will that affect the performance of the flow meter or accuracy of measurement? Behavior of the flow meter is prominently defined by the Reynolds number.
It is a dimensionless quantity which defines the relationship between momentum and velocity of fluid that can determine whether the flow or stream is laminar or turbulent. This flow meter attribute, along with the flow meter chemical compatibility materialfluid pressure and temperature will help identify the performance capabilities and accuracy of the flow meter for the specific liquid or gas application.
