Calibration Verification Practices
Rosemount 8800D Vortex Flowmeters (HART
INTRODUCTION
This guideline is intended for users of Rosemount
8800D Vortex flowmeters to develop plant specific
calibration/verification procedures and is focused
on procedures that do not require the removal of
the vortex meter body from the line or shutdown of
the line. This document shall provide the basis for
verification of the calibration of Rosemount 8800D
Vortex flowmeters. It does not include calibration
applications associated with the F
fieldbus communication protocol. It was prepared
by Technical Specialists at Rosemount Flow
Division's headquarters in Eden Prairie, MN, USA.
Overview
This section is for the use of those who are
generally experienced in the calibration and
verification of electronic transmitters including the
use of a Field Communicator and/or AMS Device
Manager. It is not intended to replace the general
calibration/verification procedures as detailed in
Section 2, the 475 Field Communicator Manual, or
the Rosemount 8800 Vortex flowmeter user's
manual. This section will outline the
documentation and hardware required for
calibration/verification of the Rosemount 8800
Vortex flowmeter.

Hardware and Tools Required:
Power supply, 10-55 VDC
1
Multi-meter, 4-
/
digits (within NIST
2
traceable calibration compliance time
period)
475 Field Communicator or AMS Device
Manager
Precision Load Resistor: 250 ohms +/-
0.01% 2 watt or 500 ohms +/- 0.01% 2 watt
Jumper wires with end connectors
Temperature Sensor Calibrator or Calibrated
Oil Bath (MTA Option Only)
Pre-Configuration Checks (Field
Communicator not connected to transmitter)
Verifying the Security Jumper Status
Insure that power is removed from the transmitter.
Remove the housing cover opposite the field
terminal side. Position the security jumper as
desired. If the Security jumper is not installed –
SECURITY OFF (NOT write protected).
