Component Properties – LDARtools

While a small number of these properties are required fields (denoted with *), you can customize your database by hiding properties that will not be used.

Your database will operate faster in some circumstances after hiding any properties you are not using. Of course, you can always put them back in the future, if needed.

To customize this aspect of your database, please reach out to our Support Team to get started. In the issue notes, just tell us which properties you want to hide or display.

There are two categories of properties:

Main Properties List

Property	Definition
Area	Geographical area designed as a part of a LUnit for helping group or locate components.
Barcode	Component has a barcode tag.
Batch Group	Field for tracking when a component is a part of a batch process.
Battery Limit	YES / NO field to indicate if a component is within a battery limit.
Building	Used for identifying a component with a specific building.
Cancel DTM Frequency	Checking this box will classify a DTM as an fDTM. This would be done when a particular LUnit or Process Unit has more DTMs (as a % of all valves) than the regulations allow. This will cause the DTM to be monitored at the base frequency of the component rather than on an annual basis. See the DTM article for more information.
Confined Space	Located in a confined space and requires a special permit.
Custom Field 1-5	Before using one of these custom fields, please contact our Support Team. We will work to help you avoid it!
CVS	Closed Vent System. A system is not open to the atmosphere and is composed of hard-piping, ductwork, connections, and, if necessary, flow-inducing devices that transport gas or vapor from a piece(s) of equipment to a control device, or back to a process.
Date Added	The date the component was added to the database and made Active.
Department	Used for identifying a component with a specific department.
Drawing	Used for identifying a Component with a specific Drawing.
DTM	Elevated component considered Difficult to Monitor.
DTM How	The specific method for getting to this DTM, such as Ladder, Manlift, Scaffolding, etc.
DTM Why	The specific regulatory approved reason why a component is marked as a DTM.
EP Number	EPN Reference Number.
Extra Seams	Indicates there is/are more than one seam on a component requiring special attention from the monitoring technicians and should trigger an additional seam for the purpose of calculations emissions. For instance, if you record a compressor as having 1 extra seam, then the technician can be told that in Chateau Mobile, and when the emission calculations are done, Chateau will add the extra emission for the additional seam.
Facility	The highest level of component classification. Multiple Facilities can be created in one instance of Chateau. Plants are nested within each facility. Most databases will have one facility.
FIN	Facility Identification Number
Flag	If this component was tagged in a SmartFlag project, you can reference the flag number here. Note: SmartFlags was discontinued on 10/8/2025 and is no longer a supported feature. See Add Via Photo.
Floor	Use for identifying a component with a specific floor.
Insulation	Describes the nature of any insulation which might be present on a component. The values relevant to your program should be loaded into the Insulation picklist in Settings / Picklists / Category = Component.
Isolatable	YES / NO field to indicate if a component is capable of being isolated from VOC service.
Isolatable Source	Text field for documenting the person who provided the information on which isolated field was populated.
Latitude/Longitude	Chateau collects the GPS coordinates from inspections performed on this component and uses them for the latitude and longitude data. Each new inspection’s coordinates will be averaged with all previously-recorded coordinates so the latitude and longitude will gradually be as accurate as possible. In order to filter out grossly-inaccurate coordinates, if the coordinate for any inspection is greater than one standard deviation from the existing average, it will not be factored in. In cases where a significant amount of inspection coordinates are incorrect, our support team can wipe the past coordinates so you can start over.
Level	Used for identifying a component with a specific level.
Location Description	Text field describing the precise location and identification of each component.
LowE Detail	Field for tracking a customizable list of Low Emissions properties. Develop this list in Settings / Picklists / Category = Component.
LowE Required	YES / NO field to indicate if a component is subject to Low Emissions requirements.
LUnit*	Stands for Location Unit. This is the basic identification level for all components identifying where it’s located. Essentially, it tells the technician where to get a safety permit to enter the LUnit. It is possible all LUnits can be nested in a single plant within a single facility. In many cases, the LUnit will be the same as the Process Unit. But in other—important cases—the two different properties may need to be tracked differently. A tank (in a tank field), for instance, may be assigned to the LUnit named “Tank Field,” but also assigned to the Process Unit where the material in the tank was produced. In most cases though, both are the same. See Process Unit for more details.
MMQ Group	For MMQ frequency components on the final phase of MMQ, this indicates which month of the quarter the component will be scheduled for monitoring. This is a customizable component property.
MMQ Phase	Indicates the current phase of component with an MMQ frequency. M1/Q1 for the first month/quarter of the phase, M2/Q2 for the second month/quarter, and MMQ for when no leaks happened in the first two periods and the components is now on quarterly/annual.
NDE	An item is classified as having been built to the standard of Non-Detectible Emissions.
OGI Site Identifier	YES / NO field indicating if a component is being used as an OGI Site Identifier for image confirmation purposes.
P&ID	For recording the P&ID number with which a component is associated.
Permit Group	Used for identifying a component with a specific Permit Group.
Physical State*	Light Liquid (LL), Gas/Vapor (GV), or Heavy Liquid (HL).
Piping Segment	Used for identifying a component with a specific Piping Segment.
Plant	Multiple plants can be nested into any facility. You will then nest any number of LUnits within any plant. It is possible you will have one or more plants.
POEL	YES / NO: Indicates if a component is a Potential Open-Ended Line. This field will enable you to quickly build a tour to perform a field audit of all your POELs.
Profile*	Identifies the current operating status of the component: Active, Inactive, TUPurged, TUInService This list cannot be edited.
Process Section	Used for identifying a component with a specific Process Section. This field is useful if you have a specific group of components covered by a special permit.
Process Unit	Allows you to sort, track, manage and report components by Process Units, which may be different from LUnits (used for Locational purposes). For instance, report components from the originating LUnit to Tank Farm and Storage, you can use this field. See LUnit for more details.
QQA Group	For QQA frequency components on the final phase of QQA, this indicates which quarter of the year the component will be scheduled for monitoring. This is a customizable component property.
REN	Reference Equipment Number: ID of a major piece of equipment used to group and sort components for identification and route sequencing purposes.
Route Sequence	Numeric sequence applied to all components indicating the physical order in which the technician should monitor them. In a Tour in Chateau Mobile, the components will normally be sorted according to the Route Sequence in ascending order. If the components have no Route Sequences, they will appear in random orders in Tours. If you would rather use the Tag Number sequence to sort the components in the Tours, then go to Settings / Miscellaneous and enable Sort Tours by LUnit then Tag (not Route Sequence). If you do not have Route Sequences already, here are your options: Use the Modify Route Sequence feature to set the preferred route sequence Go to Settings / Miscellaneous and enable Sort Tours by LUnit then Tag (not Route Sequence) if your tag numbers resemble the order in which you want them inspected. If you have an upcoming data remediation project, update the Route Sequences in Add Via Photo.
Safety Equipment	Used for specifying safety equipment that might be required for monitoring a component. Develop this list in Settings / Picklists / Category = Component.
Size	The physical dimension indicating a characteristic of a component expressed in inches or a fraction thereof. This will dictate the minimum M21 monitoring time, assuming the Inspection Sample Times are set up.
Stream	Identifies the process stream the component is in contact with.
Structure	Used for identifying a component with a specific structure.
Sub-Area	Geographical area designed as a part of an area for helping group or locate components.
SubREN	Locational modifier for a REN, such as level or compass direction, enabling the grouping of all components North of a REN, or on the top of a REN together.
SubSubType	A more precise component identification type involving a breakdown within the SubType category. For example, Orifice, Blind, Freestanding, and Valve End are SubSubTypes of the Connector SubType of Flange.
SubType	Special types of certain kinds of components. Check valve and block valve are SubTypes of valves. Flange and threaded are SubTypes of connectors. Canned or diaphragm are SubTypes of pump.
Tag*	In Chateau, the tags can consist of numbers, letters, special characters, or any combination thereof. Also, you do not have to use padded zeros. Chateau recognizes tags with decimal numbers (e.g., 1.001, 1.002, 1.003) as Subtags of the corresponding whole number (e.g., 1), but does not recognize lettered tags (e.g., 1a, 1b, 1c) as Subtags.
Type*	Component Type, such as Valve, Connectors, Pump, etc.
UTM	Unsafe to Monitor.
UTM Why	Indicates why a component has been classified as UTM.
Work Scheduled	Indicates a month in which a component is preferred to be monitored that is more specific than the regulatory schedule requirement. See the Work Schedule article for more details.

Custom Properties

If the properties currently available in your database do not meet your specific needs, please contact our Support Team to request the addition of custom properties. When submitting your request, be sure to include the following details:

The name of the property
Whether it should be a text field, or a Yes/No field
Whether it should be added to the Main Properties list, or the Exemption Fields

Example: If you would like to add “Welded” as a property to exempt a component from monitoring, please let us know “Welded” should be a Yes/No field under the Exemption Fields.

Once we confirm the property has been added, don’t forget to update the Chateau Mobile fields to ensure the new property appears on your technician’s handheld devices.

Note: Custom added properties will not appear in the Query Builder on any grids in Chateau.
