IL01.
Two characters have been used to identify the Instrument Type and there is no need to use a modifier. The
total number of characters in this code is 13.
If Instrument Loop WP025-IL01 contained two flow indicators then the Instrument Locations would be
WP025-IL01-FI01 and WP025-IL01-FI02. Two characters have been used to represent the Instrument Type
(FI) and two digits have been used to represent the Modifier (01 for Flow Indicator 1 and 02 for Flow
Indicator 2). The total number of characters in this code is 15.
The format of the Instrument Location description is:
W; X Y
Where:
W is the description representing the Instrument Loop (see 4.3.4 Level 4 – Instrument Loop (Simple
Facilities) for standards related to describing an Instrument Loop).
X is the description representing the Instrument (see 4.4.2 Instruments (Complex and Simple Facilities)

4.4 Units and Instruments
Units and Instruments have the same coding and naming convention irrespective of whether they are part of
Complex or Simple Facilities.
4.4.1 Units (Complex and Simple Facilities)
Units exist at Level 8 for Complex Facilities and Level 6 at Simple Facilities. A Unit is a physical asset which
is mechanical, electrical or structural. In the vast majority of cases each Unit is located under a single Unit
Location, however in special cases a Unit may be located under an Instrument Location or under both a Unit
Location and Instrument Location simultaneously (see Section 4.5 Hierarchical Relationships for Units and
Instruments for further details).
Each Unit has an alpha numeric code and an associated description.
If the Unit has been tagged in the field then the format of the code is:
ANXXXXXX
Where:
AN is the code representing the term “Asset Number”.
XXXXXX is a 6 digit sequential number which is unique when used with the “AN”
prefix.
If the Unit has not been tagged in the field (due to technical limitations) then the format of the code is:
NTXXXXXX
Where:
NT is the code representing the term “No Tag”.
XXXXXX is a 6 digit sequential number which is unique when used with the “NT” prefix.
The naming convention for the description of a Unit depends on whether the description of the associated
Unit Type contains a forward slash and whether it has an associated Sub-Type (refer to 9.5 Unit Location
Suffix for a list of available Unit Types).
If the associated Unit Type is not configured in the corporate asset management system with a Sub-Type
then the Unit description is:

Refer to 9.6 Unit Sub-types for a list of available Sub-types.
Examples of Units (codes and descriptions) include:
AN001234 – Motor Control Centre
AN001156 – Collector - Screw
NT000298 – Pump - Integral Motor (Centrifugal)
A full listing of Units is detailed in the corporate asset management system.
4.4.2 Instruments (Complex and Simple Facilities)
Instruments exist at Level 8 for Complex Facilities and Level 6 at Simple Facilities. An Instrument is a
physical asset that measures and/or regulates physical quantity/process variables such as flow, temperature,
level, or pressure. In the vast majority of cases each Instrument is located under a single Instrument
Location, however in special cases an Instrument may be located under a single Unit Location or under
multiple Instrument Locations simultaneously (see Section 4.5 Hierarchical Relationships for Units and
Instruments for further details).
Each Instrument has an alpha numeric code and an associated description.
If the Instrument has been tagged in the field then the format of the code is:
ANXXXXXX
Where:
AN is the code representing the term “Asset Number”. Note: the majority of instruments in the
field still have an “LMI” number. All new tags applied to assets in the field will conform to the
“AN” coding convention.
XXXXXX is a 6 digit sequential number which is unique when used with the “AN”
prefix.

A full listing of Instruments is detailed in the corporate asset management system.
4.5 Hierarchical Relationships for Units and Instruments
4.5.1 Common Scenarios
In the vast majority of cases, each:
Unit is located under a single Unit Location; and
Instrument is located under a single Instrument Location.
Exceptions to the common scenarios are detailed in the following sub-sections.
4.5.2 Instrument not Part of an Instrument Loop
An Instrument is not created as part of an Instrument Loop if it satisfies at least one of the following criteria:
It is part of a piece of equipment and only applicable to the equipment, and does not display
readings or set alarms off anywhere (e.g. pressure switch).
It will be run to failure or very infrequently maintained.

If an Instrument is not part of an Instrument Loop then it will be located under a Unit Location within an
Equipment Location.
4.5.3 Unit with Integral Instrument
In this case the physical asset is predominantly mechanical or electrical in nature but has some
instrumentation to assist in carrying out its function. Examples of Units with Integral Instruments include:
Sampler
Chlorinator
Suphunator
Valves (with integral position transmitters)
VSD (with integral speed controller)
Metering / Dosing Pumps
A Unit with integral instrument is located under a single Unit Location within an Equipment Location and a
single Instrument Location within an Instrument Loop (i.e. it has two parent assets).
4.5.4 Unit that Supports an Instrument Loop
In this case the Unit serves no other purpose but to provide an Instrument Loop with a specific function. In
addition, the Unit would be disposed if the Instrument Loop were replaced.
A Unit that supports an Instrument Loop is located under an Instrument Location within an Instrument Loop.
5 Field Labelling Requirements
The following levels in the asset hierarchy require labelling in the field:
Equipment Location
Unit Location
Instrument Loop
Instrument Location
Unit / Instrument
Valve Location – Manual
Dam Structure Monitoring Location
