Most issues with electromagnetic flow meters start with installation. We have known many companies to install an electromagnetic flow meter without the minimum requirements or instructions. When they complain about inaccuracy, field techs often find out that someone installed the meters incorrectly or in applications that wouldn’t support them.

How to install an electromagnetic flow meter

You won’t find any mysteries here. You need a minimum inlet and outlet run, a product with the minimum conductivity needed for your type of electromagnetic flow meter, and most importantly: full pipes. If you have earthing rings on hand, they also won’t hurt.

Now that you have an idea of how little it takes, let’s fill in those basics with some details. Before I do, you should know that these conditions can vary by vendor and model, so double check before installing.

Electromagnetic flow meter installation requirements

  • The market standard for minimum conductivity seems to hover around five micro-siemens per centimeter, although you can find devices above and below that standard.
  • You should aim to install electromagnetic flow meters vertically with the flow going up. That way, you always have the pipe full or empty.
  • You can install them horizontally, just make sure you install the transmitter correctly. For high temperatures, you should install it upside down.
  •  You’ll find different recommendations on inlet and outlet runs, but you often see at least five times the diameter before the electromagnetic flow meter and two times after.
