Expert’s answer: How to do a Yokogawa AXR field zero adjust

Of course I can show you how to do a Yokogawa AXR field zero adjust. First, you need to set up the pipe. Make sure it’s completely filled without flow. You need a valve before and after the meter to do this. You may even need a bypass, but you gotta do what you gotta do!

Once you have made the pipe completely filled without flow, then check the flow indication on the local display. The display should indicate zero flow. If not, then you need to do the zeroing adjustment. On the display, go through these menus:

Setting Mode > Adjustment > Auto Zero Exe > Execution > Done

Now the transmitter will do the zero adjustment. If you did the procedure correctly, then the meter will indicate zero flow. For more information, go to page 142 in the technical manual.

I have 10 field flow meters from Yokogawa, and I’d like to do loop tests directly on the display, instead of a field communicator. Could you give me the step by step?

Yokogawa AXR installation requirements

Hi there. Is there a minimum upstream and downstream pipe when I install an electromagnetic? I’m afraid that in my installation we won’t have enough space, so wanted to ask, what’s the impact and what’s the requirement?

Yokogawa AXR limitations

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?
