Hi. We want a flow meter that can save us money on installation, and we heard about loop-powered devices. Can you tell us more about the Yokogawa AXR, specifically what limitations it has?
Expert’s answer: Yokogawa AXR limitations
Loop-powered magmeters like Yokogawa AXR have surprisingly few limits. Sometimes, you won’t have a two-wire device in the exact size or accuracy you need from one manufacturer or another, but that’s about it.
Today, most of the options on the market offer the same level of quality that as a four-wire device. For a new application, you should use a loop-powered device to save money on the installation.
However, when we talk about loop-powered Coriolis meters, we still have size limits. Sometimes you’ll run into a “fake” loop-powered device, where you have to install a converter to have the 4-20 mA.
So in your case, you can install a loop-powered magmeter without fear and reduce your installation costs!

It gives a reading if there is nothing passing through it. I removed it and found no coating or damage to the internal wall. I just wondered if there is anything else I can check?
