Verify Mass Flow Measurement; Verify The Zero - Emerson Micro Motion 5700 Configuration And Use Manual

Quick start
March 2019
If your sensor does not show an FD value, contact customer service.
If your sensor tag does not show a DT or TC value, enter the last 4 characters of the density calibration factor.
In the sample tag shown above, the value is shown as 4.44.
Do not confuse the Meter Factor line on the pictured sensor tag with any meter factor settings discussed in
this manual.

2.10 Verify mass flow measurement

Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available
method.
Procedure
Read the value for Mass Flow Rate on the transmitter display.
•
Menu > Operations > Process Variable Values
Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables
•
panel.
Connect to the transmitter with the Field Communicator and read the value for Mass Flow Rate.
•
Online > Overview > Mass Flow Rate
Postrequisites
If the reported mass flow rate is not accurate:

2.11 Verify the zero

Display Menu > Service Tools > Verification & Calibration > Meter Zero > Zero Verification
ProLink III Device Tools > Calibration > Smart Zero Verification and Calibration > Verify Zero
Field Communicator Service Tools > Maintenance > Calibration > Zero Calibration > Perform Zero Verify
Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field
zero can improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the meter unless one of the
following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
