Hi @noelfaithfulkari2857, There are location, environmental, and position considerations when it comes to Mag sensor installation which Section 3 of the 8732 Manual covers into more detail. Here is the link to the 8732 Manual:
We also will be releasing a new set of videos that covers preparation for installation and the installation process for Mag meters. Please check back soon for these new videos!
i used 8750w, when pipe is empty flow then transmitter show numers. how to set to zero reading. anorher issue was unstable of reading. hope you help our problem, thanks.
Hi @udansyambasul, The Rosemount 8750W, along with the other Rosemount Mag transmitters, come standard with Tunable Empty Pipe Detection diagnostic. This diagnostics provides a means of minimizing issues and false readings when the pipe is empty. Tunable Empty Pipe Detection diagnostic is set at the factory to properly diagnose most applications but can be optimized to meet unique applications.
1. Record the empty pipe value with a full pipe condition. Example: Full reading = 0.2 2. Record the empty pipe value with an empty pipe condition. Example: Empty reading = 80.0 3. Set the empty pipe trigger level to a value between the full and empty readings. For increased sensitivity to empty pipe conditions, set the trigger level to a value closer to the full pipe value. Example: Set the trigger level to 25.0 4. Set the empty pipe counts to a value corresponding to the desired sensitivity level for the diagnostic. For applications with entrained air or potential air slugs, less sensitivity may be desired. Example: Set the counts to 10
This procedure can also be found in section 9.3.2 of the Rosemount 8750W Manual that can be accessed through this link:
Thanks for knowledge sharing. What's the procedure for installation

The flowmeter rosemount is fault ,rate waving too much how work maintenance . Please
