Section A Introduction
Scope
The Eldridge Products, Inc. Series 8000 Master-Touch mass flow meters Revision 1 is HART Protocol
Revision 6.0. enabled. This document specifies all the device specific features and documents the
HART Protocol enabled details. The functionality of this Field Device is described sufficiently to
allow its proper application and its support in HART capable Master Applications.
At this time EPI does not provide a Device Description (DD) file. A DD is not required for
communication with HART-enabled devices. It is an optional enabling element of HART
technology
Purpose
This specification is designed to compliment other Series 8000MP and 8000MPNH Master-Touch
documentation by providing a complete description of this Field Device from a HART Enabled
communication perspective.
Document Use
This specification is designed to be a technical reference for HART-enabled Master Application
Developers, System Integrators and knowledgeable End Users. It also provides functional
specifications used during Field Device development, maintenance and testing. This document
assumes the reader is familiar with HART Protocol requirements and terminology. For information
concerning the functions of the Master-Touch flowmeters, please see the Master-Touch Instruction
Manual.
Device Identification
Manufacturer Name:
Eldridge Products, Inc.
Model Name(s):
Series 8000
Manufacturer ID Code:
240
Device Type Code:
128
HART Protocol Revision:
6.0
Device Revision:
1
Number of Device Variables:
2
Software Revision:
1
Physical Layer Supported:
FSK
Hardware Revision:
1
Default Polling Address
0
Device ID:
See Note 1
Note 1: The first digit of the EPI serial number was dropped to create the HART Device ID. For
Example: 25051003 will become 5051003.
The tag, long tag, message, date, descriptor, polling address, and final assembly numbers are set to 0
at default. These values are stored in EEProm and changeable via HART commands. When changing
items such as the polling address, the old address is used to send the response data. At the
subsequent command the new address would be used.

The Primary Variable is the Flow Rate value. The Units code is dependent on the customer specific
requirements of the device. Please see the Master-Touch Instruction Manual for specifics regarding
the Flow Rate.
The Secondary Variable is the Totalizer. The units are dependent on the Flow Rate units. Please see
the Master-Touch Instruction Manual for specifics regarding the Totalizer.
Status Information
When the field device is reset or powered on, the CS status will be reflected per the HART spec.
Universal Commands
This field device supports all the Universal Commands listed in HART 6.0 Specification.
Commands 4, 5, and 10 are reserved per the HART spec and the field device will respond with a
response code of 64 – Not Implemented
Command 15’s damping value is set to 0 and has no meaning.
Tag, Descriptor, Date, Long Tag, Message, Final Assembly Number are stored in EEProm as
received from the Master. This device does not interrogate the data within these variables.
