You'll find a few general installation tips here that will help you figure out what to think about while designing and installing your flow meter such as a vortex flow meter. 

1. Make sure the fluid you're weighing is a single-phase fluid. 
Make sure the fluid you're weighing is a single-phase fluid, which means it's either a gas or a liquid. If the fluid is two-phased, the flow meter must be selected with the intention of accurate measurement under such conditions in mind. 

2. Make sure the flow meter is pointing in the right direction. 
The orientation of a flow meter's installation can have a significant impact on the meter's efficiency and accuracy. With the exception of the Rotameter, which can only be placed vertically with a flow from bottom to top, most flow meters can be built in any direction. 

3. The fluid must always be present when installing a flow meter for gas/liquid applications. 
Even if there is no flow, the flow meter should always be put in a position where it is loaded with the fluid when installing a gas or liquid flow meter. For the second undesired step, there should be an escape route available. 

4. The installation of a flow meter for gas/steam applications should be done at a high point. 
When pressure and temperature conditions cause the gas to transform into a liquid, the liquid is formed. Any condensate stuck in the lower part of the pipe as a result of this would be trapped. As a result, flow meters for gas or steam applications should always be installed at a high point in horizontal piping to allow liquid to drain away from the flow meter. 

5. Install the piping in such a way that bubbles aren't created. 
Gas escapes the liquid solution as a result of a sudden pressure drop in the flow line. Cavitation is the term for this phenomenon. Valves and sharp shifts in diameter are vulnerable to gasification. As a result, it's important to mount the piping in such a way that bubbles don't form. 

Now that you've heard about the most important things to remember while installing a flow meter, you'll be able to get the most out of your system. You can now move on to determining which flowmeter is best for your application in the next phase.
