INTRODUCTION TO HART ®FIELD DEVICE SPECIFICATIONS
Scope
The Universal Flow Monitors water flow transmitter, model ME Transmitter complies with HART Protocol Revision 7.0. This
document specifies all the device specific features and documents HART Protocol implementation details (e.g., the Engineering
Unit Codes supported). The functionality of this Field Device is described sufficiently to allow its proper application in a process
and its complete support in HART capable Host Applications.
PURPOSE
This specification is designed to complement other documentation (e.g., the installation manuals specific to PI, MN/MM/MH/
model flow meters) by providing a complete, unambiguous description of this Field Device from a HART Communication
perspective
WHO SHOULD USE THIS DOCUMENT?
The specification is designed to be a technical reference for HART capable Host Application Developers, System Integrators and
knowledgeable End Users. It also provides functional specifications (e.g., commands, enumerations and performance
requirements) used during Field Device development, maintenance and testing. This document assumes the reader is familiar
with HART Protocol requirements and terminology.
