How To Choose The Right Flow Meter
Simply defined, a flow meter is a device that measures how much fluid is flowing through a pipe and at what rate. In practice, however, flow meters are a little more complicated. They vary depending on the application and the degree of precision you expect, among other things.
Here are a few important points to keep in mind before purchasing a flow meter.
1. Choosing a flow meter for basic necessities
2. Choosing a flow meter based on the type of fluid
A simple way to find the right device is by looking at a flow meter's Reynold's number. Different Reynold's values correspond to fluids of different viscosity, enabling you to pick the right flow meter for the fluid at hand.
3. Choosing a flow meter based on its measurement range
4. Choosing a flow meter based on accuracy
5. Choosing a flow meter based on type
Each type of flow meter is best suited for a certain type of application or fluid. Choosing the right type is critical because the accuracy of measurement depends heavily on this factor.
Here are a couple of examples. Coriolis flow meters are great for measuring the mass (not volume) of viscous fluid flowing through a line. Electromagnetic flow meters, meanwhile, can take measurements across a wide range.
Besides viscosity and flow range, a few other factors also need to be taken into consideration while selecting a flow meter. These are:
Picking the right product can be difficult for the uninitiated.
