Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter BACnet points list
Updated 6 November 2026
The InnovaMass 240i (inline) and 241i (insertion) are multivariable vortex meters measuring flow, temperature and pressure for steam, gas and liquids. Over BACnet MS/TP they expose 21 Analog Inputs (flow, temperatures, pressure, energy, totalizer, alarm state and vortex diagnostics), 11 Binary Input fault flags and a Binary Output to reset the totalizer.
This page lists 33 BACnet objects for the Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter — 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 240i/241i Vortex Flow Meter
Read flow, temperature, pressure, the totalizer and energy flow, and watch the BI fault flags and alarm AIs. Write the Reset Totalizer BO to clear the total.
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.

Network setup
- BACnet MS/TP at 9600, 19200 or 38400 baud; baud and MAC address are set with the Smart Interface Portal (SIP) software.
Watch out for
- Units follow the meter configuration; the units in the table are sample defaults.
Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter 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 BACnet Supported Device, Object and Property tables (manual pages 17-23). Object names are the Object Name property values; units are the sample defaults shown and follow the meter configuration.
- AI-14 Viscosity shows the unit enumeration "423" in the table; it is left blank here.
- No read/write column is printed; only the Reset Totalizer BO 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 240i/241i Vortex Flow Meter and exports what it actually has to Excel — free.

Questions about the Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter
How many BACnet points does the Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter have?
This list has 33 BACnet objects: 21 analog inputs, 11 binary inputs, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter BACnet points are writable?
1 of the 33 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 240i/241i Vortex Flow Meter BACnet documentation?
The source is InnovaMass 240i/241i Series BACnet Instruction Manual (IM240i/241i BACnet), revision V3.4/19, published free by Sierra Instruments at https://sierrainstruments.com/userfiles/file/manuals/240i-241i-bacnet-instruction-manual.pdf?x=5806.
What are the minimum BACnet points to integrate the Sierra Instruments InnovaMass 240i/241i Vortex Flow Meter?
Start with AI 1 Flow (Flow rate); AI 6 Totalizer (Flow total); AI 2 Temperature1 (Process temperature); AI 4 Pressure (Process pressure); AI 5 Energy Flow (Energy flow); AI 7 Alarm Status (Alarm relay state).
How do I check these points on the real InnovaMass 240i/241i Vortex Flow Meter?
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.
