What do I need to install KROHNE’s OPTIFLUX 4000?

Flow Q&A

We are implementing a new water flow measurement, it's nothing complicated. However, we would like to know the right way to install the OPTIFLUX 4000 from Krohne. Could you share some documents with that information?

Expert’s answer

The OPTIFLUX 4000 huh? Your question is a popular one in flow meter installation. You should always find out first rather than install and find mistakes later.  Electromagnetic flow meter installation has no special secrets, but you need to pay attention to the little details.

Here we’ll list the most relevant points to check before and during your installation of the OPTIFLUX 4000. These recommendations come straight from KROHNE, so ignore them at your peril. I’ll link you to the manual as well.

OPTIFLUX 4000 installation requirements

  • Chemical properties: First, if you want to use an electromagnetic flow meter, then your product has to conduct an electrical current. Simple, right? Just make sure. You never know.
  • Flow direction: The body of the meter has an arrow on it to show the flow direction. However, you can set it up for reverse flow too. So again, make sure you have it set the way you want.
  • Inlet and outlet run: Every electromagnetic flow meter requires a minimum inlet and outlet run to allow a laminar flow. Some new meters claim that they don’t need minimum runs, but you get less accuracy from those. Your call.
  • Installation: Here you can’t have high vibration or magnetic fields because they can affect flow measurement. Also, the best way to install this meter is with the flow going up, so you always have the pipe filled or empty. However, the manual may suggest other setups for different situations.

The OPTIFLUX 4000 and all electromagnetic flow meters in general need these conditions met for their installation. While some companies offer meters that don’t need inlet and outlet runs, this choice will affect the accuracy. Remember to read the fine print to know the impact and requirements for those fancy features before you buy the meter.
