    Ultra sonic flow meter.

    Does anyone use these for chillers or heat pumps?
    How do you check the flow of the liquid trough heat exchangers?

    I have used them before. They can work very well. I usually use a pressure drop method but it certainly has it limitations.
    "Right" is not the same as "Wise".

    Don't step on my favorite part of the Constitution just to point out your favorite part.

    they work well if you set them up correctly. you have to know the exact wall thickness of the pipe, and a few other exact details....if you're off, your readings won't be accurate.

    this more of a balancing tool than a service tool.

    I use the Katflow 230 from Katronic. It has the wall thickness sensor. Works great and can log the flows.
    Otherwise I use a Comdronic if the system has a DRV on it

    We are using the Fuji meter , it is badass. It logs , reads wall thickness , etc . It's not cheap though .
