Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) BACnet points list
Updated 6 November 2026
The legacy InnovaMass 240/241 vortex meters expose a short BACnet MS/TP object list: 19 Analog Inputs (volume and mass flow, two temperatures, pressure, density, energy, two totalizers, status register, analog output channels and vortex diagnostics), four alarm Binary Inputs and a reset Binary Value.
This page lists 24 BACnet objects for the Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Sierra Instruments’s own free documentation, linked below.

BMS integration notes: Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1)
Read flow, temperature, pressure and the totalizers, and map the alarm BIs (Alarm1-Alarm3).
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| AI 1 | Volume Flow | Volumetric flow | Read |
| AI 2 | Mass Flow | Mass flow | Read |
| AI 3 | Temperature 1 | Process temperature | Read |
| AI 5 | Pressure | Process pressure | Read |
| AI 8 | Totalizer 1 | Flow total | Read |

Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- From the object property summary tables (manual pages 16-17). The unit lists in the Analog Input description table depend on the meter setup and are not repeated here.
- The last AI row is printed as "A19"; it is read as AI 19.
- The guide gives a Device Communication Control password; no read/write column is printed and only BV 1 Reset is treated as writable.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) and exports what it actually has to Excel — free.

Questions about the Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1)
How many BACnet points does the Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) have?
This list has 24 BACnet objects: 19 analog inputs, 4 binary inputs, 1 binary value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) BACnet points are writable?
1 of the 24 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.
Where is the official Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1) BACnet documentation?
The source is InnovaMass 240/241 BACnet Instruction Manual (IM240/241 BACnet), revision Rev. V1, published free by Sierra Instruments at https://sierrainstruments.com/userfiles/file/manuals/240-241-BACnet-Instruction-Manual_v1.pdf?x=2029.
What are the minimum BACnet points to integrate the Sierra Instruments InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1)?
Start with AI 1 Volume Flow (Volumetric flow); AI 2 Mass Flow (Mass flow); AI 3 Temperature 1 (Process temperature); AI 5 Pressure (Process pressure); AI 8 Totalizer 1 (Flow total); BI 1 Alarm1 (Alarm 1 state).
How do I check these points on the real InnovaMass 240/241 Vortex Flow Meter (legacy, BACnet v1)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
