Procedure III. Vortex Sensor Verification
Step 1: Signal-to-Trigger Level
A. Read Signal-to-Trigger (Sig/Tr) Level under
normal flowing conditions
HART Commands: 1 (Device Setup), 4 (Detailed
Setup), 3 (Signal Processing), 1 (Optimize Flow
Range), 3 (Sig/Tr)
A.1 IF the Signal-to-Trigger Level is >4, Sensor is
assured to be Healthy.
NOTE:
Signal-to-Trigger level will vary even at steady flow.
Verify that average of several readings remain above
4.
A.2 IF the Signal-to-Trigger Level is <4, See
Appendix B
Procedure IV: Temperature Sensor Verification
(For MTA Option Only)
Typically, temperature sensors and temperature
transmitters are verified as individual units. However,
due to the Rosemount 8800D design that uses a
Type N special limits thermocouple and a custom
interface between the thermocouple and the
electronics, best practice is to verify the components
as a system.
Step 1:Remove thermocouple from meter
body
A.Turn off power to the Rosemount 8800D.
B. Remove the thermocouple from the meter
body by using a 1/2-inch open wrench.
NOTE:
Use plant approved procedure for removing a
temperature senor from a thermowell.
C. Remove the thermocouple from theelectronics
by using a 2.5 mm allen wrench to remove the
cap head screw from the electronics.
D. Gently pull the thermocouple connector from
the electronics.
Step 2:Remove electronics housing from the
meter body
NOTE:
If removing the electronics housing is not desired, a
spare set of electronics may be used for temperature
sensor verification.
A.Turn off the power to the Rosemount 8800D.
B. Disconnect the wires and conduit from the
housing.
C.Loosen the screw on the support tube access
cover if present.
D. Remove the access cover (if applicable).
E. Use a 5/32-inch hex wrench to loosen the
housing rotation screws (at the base of the
electronics housing) by turning the screws
clockwise (inward) until they clear the bracket.
F. Slowly pull the electronics housing no more
than 1.5 in. (40 mm) from the top of the
support tube.
NOTE:
Damage to the sensor cable may occur if the sensor
cable is stressed.
G. Loosen the sensor cable nut from the housing
with a 5/16-in. open end wrench.
Step 3:Reconnect thermocouple to
electronics
A. Insert the thermocouple connector into the
electronics housing using care to align the pin
and the cap head screw.
B. Tighten cap screw with 2.5 mm allen wrench.
Step 4:Bring thermocouple and electronics
assembly to the designated temperature
sensor calibrator or precision liquid bath
NOTE:
System accuracy shall be no less than ±0.025 °C
(±0.045 °F).
System stability shall be no less than ±0.025 °C
(±0.045 °F). Extreme care should be taken that the
calibration source is operating properly and within
specifications.
A. Connect power to the Rosemount 8800D.

Rosemount 8800D
Step 5:Set temperature sensor calibrator or
precision liquid bath to a set point of 100 °C
(212 °F)
A. IF Process Temperature value in the
electronicsmatchesthe referencetemperature
sensor within 2 °C (4 °F), then the
thermocouple is healthy and within
specifications.
B. IF Process Temperature value in the
electronicsmatchesthe referencetemperature
sensor within 2 °C (4 °F), then repeat with a
new electronics and thermocouple to verify the
calibration source.
B.1. IF the new set of electronics and
thermocouple works, then contact your
local Rosemount representative for
assistance with returning the unit to the
factory.
B.2. IF the new set also fails, then verify the
calibration source.
HART Command: 1 (Device Setup), 1 (Process
Variables), 4 (View Other Variables), 9 (Process
Temperature)
Procedure V: Perform Density Test Calculation
(For Use Case II Only)
For Use Case II – copy from above, the electronics
verification was performed using a fixed process
density. When the device is in Tcomp Sat Steam
mode, the process density is dynamically calculated
from the measured process temperature. This
procedure will verify that the electronics can
calculate the corresponding density of saturated
steam for given process temperatures.
Step 1:Verify Process Fluid is set to Tcomp
Sat Steam
HART Commands: 1 (Device Setup), 3 (Basic
Setup), 2 (Process Config), 2 (Process Fluid)
Please note you MUST SEND the data whenever
changes are made.
Step 2:Enter Density Test Calculation
HART Commands: 1 (Device Setup), 2 (Diagnostics
and Service), 1 (Test/Status), 3 (Density Test Calc)
Step 3:Enter a process temperature of interest
between 80-320 °C (176-608 °F)
Step 4:Compare calculated density to ASME
Saturated Steam Table found in APPENDIX C
Procedure VI: Meter Body/Shedder Bar
Verfication (Required)
NOTE:
Shedder Bar inspection is not required in the vast
majority of applications. It is very unusual that a
vortex flowmeter will require re-calibration for
shedder bar wear in normal applications. (Vortex
meters count the frequency of shedding which is
proportional to the fluid velocity – and is not highly
sensitive to edge sharpness). Exceptions to this are
highly corrosive applications, or applications with
high levels of suspended solids. Wear in these types
of applications may be significant enough to cause a
shift in the meters K-factor, and require re-calibration.
This is an unusual circumstance.
If shedder bar wear is suspected, the following steps
can be followed to determine if it is significant
enough to warrant re-calibration.
Step 1: Remove meter from process line.
Step 2: Inspect Shedder Bar leading edge for
sharpness.
A.Visual Inspection
This requirement may be considered satisfied
by visual inspection if the edge does not seem
to reflect a beam of light when viewed with an
unaided eye.
Procedure VII: Wet Calibration (If Required)
If the criteria of Procedures I through VI cannot be
met or completed successfully the meter body should
be re-calibrated by a certified Flow Test lab. If
convenient, the meter can be sent back to the
Rosemount Factory in Eden Prairie, MN, USA or a
local Rosemount Service center that supports vortex
calibration. If this is impracticable due to location, all
developed industrial nations will have National
Technical Standard-certified Flow Labs which may
perform this service.

APPENDIX B: VORTEX SENSOR HEALTH
VERIFICATION
Verifying Vortex Sensor if Signal-to-Trigger Level is
less than 4
STEP 1: Check Sensor and sensor lead wire for
shorts
a) Isolated from the process
b) Can be checked with no process shutdown
c) Single sensor for all designs, line sizes
d) Can be replaced in the field without impacting
calibration and without breaking the process seal(1)
PROCEDURE STEPS:
1. Loosen the three housing rotation screws with
Allen head wrench.
2. Slowly pull electronics housing - NOT MORE
THAN 2 INCHES from top of support tube (To
avoid damage to lead wire).
3. Loosen and remove sensor cable nut (using a
5/16-in. wrench)
4. Using Multi-meter touching co-axial connector
pin (and grounded to meter body), verify that
sensor impedance is > 1 megaohm.
5. If multi-meter reads short, sensor must be
replaced*. See Reference Manual for details.
A special connector has been developed to make
this measurement easier. A part is available from
www.pasternack.com and is part number
PE36517-18. A picture of the connector can be
found below:
STEP 2: Check Sensor/Post Interface for damage
PROCEDURE STEPS:
1. Sensor should only be checked for mechanical
damage if all other potential sources have been
checked first.
2. Sensor/Post interface is important, and can be
damaged when removing or inserting sensors.
3. Sensor should fit on post snugly. If sensor can
be removed (pulled) from post easily, it likely
has been damaged from a slug flow or water
hammer, and should be replaced with a new
sensor(1).
4. Sensor/Post interface should be round. If
damaged, it may be slightly ‘ovaled’.
5. Sensors should not be removed and reinstalled
more than once, due to the potential for
damage.
(1) Although no process seal is broken, it is recommended
that the pipe be de-pressurized when replacing sensors
