2.1 Serial numbers
No spaces between characters of serial numbers
Enter the serial number indicated on the device information plate with no spaces between characters.
- Enter the serial number of:
- the device or component as indicated on the information plate of the device, with no spaces between characters (more information on entering the serial numbers of volumetric devices is found later in this section);
- the primary device in the Serial number field.
- the secondary device in the Secondary serial number field (any additional components will be added separately).
Refer to the Online Reporting Application User manual for information about adding and/or updating device information.
Missing or illegible serial numbers
- If the serial number of a device cannot be determined, after verifying in ORA, contact the nearest Measurement Canada office or the ORA support desk.
- If the serial number still cannot be found, create a unique one in accordance with Measurement Canada’s bulletin GEN-39.
- Enter “replacement plate” in the Comments field.
Multiple devices with the same primary serial number
ORA does not accept multiple devices with the same primary serial number in the same establishment, unless a secondary serial number allows for their differentiation. The only active devices should be the ones with the correct primary and secondary serial numbers.
Incorrect serial numbers in ORA must be updated (e.g. a “B” was entered when it should be an “8”).
Gravimetric devices
- Primary serial number: load receiving element (base)
- Secondary serial number: electronic indicator
- Components: computer, load cell, etc.
Weighing systems with multiple load receiving elements
For definitions and configuration scenarios for weighing systems with multiple load receiving elements, refer to STP-26.
Type 1: Multiplex scales
- Each load receiving element must be a separate device in ORA.
- Each load receiving element must be identified in some manner to prevent confusion (e.g. scale A, scale B).
- The same indicating element must be entered for each of the load receiving elements.
Type 2: Multi-deck scales
- Each load receiving element and its corresponding indicating element must be entered as a separate device in ORA.
- The primary serial number is that of the load receiving element and the secondary serial number is that of the corresponding indicator.
- For each multi-deck scale, indicate in the device Comments field the serial numbers of all the primary elements that form the multi-deck scale.
- Example: Primary element serial numbers 123456, 784569 and 123 form a multi-deck scale.
Replacement indicators (loaner or spare)
For installation, examination, usage and marking requirements, as well as definitions, refer to bulletin M-20.
- When a load receiving element has a spare indicator, it will be captured twice in ORA, creating two distinct devices: once with the in-service indicator, once with the replacement indicator.
- When used as a replacement indicator, you must indicate “spare indicator for scale [xxx]” or “loaner indicator for scale [xxx]” in the Comments field.
Addition and removal of indicators in ORA
Do not change the existing indicator serial number when a new indicator has been installed. To add a new indicator to an existing base, you must create a new device (scale and new indicator). You must then deactivate the old device (scale and old indicator).
Volumetric devices
- Primary serial number: measuring element (meter)
- Secondary serial number: register (indicator)
- Components: automatic temperature compensator (ATC), pulser, etc.
Notes:
- A single fuel dispenser (i.e. one meter housed within the cabinet) or high-speed dispenser approved as a complete unit with an integral register has a single serial number for the entire device.
The following examples illustrate how to enter serial numbers in ORA.

8Q60-22185B

A174-5614
- For fuel and high-speed dispensers, where more than one meter is housed in a cabinet and each has a designator code (e.g. A1, B) and a common serial number, enter the designator code and serial number for each meter as they appear on the information plate.
The following examples illustrate how to enter serial numbers in ORA:

A11001100801
B11001100801

A1020721215B
B1020721215B

A3091197184B
B1091197184B
B2091197184B
B3091197184B
- For fuel and high-speed dispensers, where more than one meter is housed in a cabinet and each has a common serial number and a designator code that is indicated separately from the common serial number (i.e. on a separate line or somewhere else on the information plate), the designator code must follow the serial number.

- When a dispenser has been retrofitted with an approved replacement register or an ATC, record both the serial number of the dispenser and that of the register.
- Most bulk metering systems consist of a primary component and one or more separately approved secondary components, each having their own information plate and serial number.
- To ensure consistency, wherever possible, compare the database serial numbers with the new serial numbers to ensure that they were recorded in exactly the same format. Corrections and recommended deletions should be flagged for the ORA support desk.
