Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP BACnet points list
Updated 12 November 2026
The FT1 is an insertion or inline thermal mass flow meter for gases. With the RS485 option set to BACnet MS/TP it acts as a BACnet Smart Sensor with four Analog Inputs: flow, gas temperature, flow total and elapsed time since the total was reset.
This page lists 4 BACnet objects for the Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Fox Thermal’s own free documentation, linked below.

BMS integration notes: Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP
Choose BACnet in the COM menu, set baud, MAC, Max Master, device instance and name, power cycle, then read AI 1 flow and AI 3 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.
| Object | Name | Why | Access |
|---|---|---|---|
| AI 1 | Flow | Gas flow rate | Read |
| AI 3 | Total Flow / Reset Total | Flow total since last reset | Read |
| AI 2 | Gas Temperature | Gas temperature | Read |
Network setup
- In I/O > COM set Comm=BACnet, then baud (9600-115200), MAC (0-127), Max Master, device instance (0-4194303) and device name (9 characters max).
- A power cycle is needed before new communication settings take effect.
- Device profile is BACnet Smart Sensor (B-SS); Fox Thermal vendor ID 650.
Watch out for
- Modbus RTU and BACnet MS/TP are only available if the RS485 option was ordered from the factory.
Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP 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.
| Description | States | |||||
|---|---|---|---|---|---|---|
| AImin | 1 | Flow | Gas mass flow rate | Read | ||
| AImin | 2 | Gas Temperature | Gas temperature | Read | ||
| AImin | 3 | Total Flow / Reset Total | Flow total since last reset | Read | ||
| AI | 4 | Elapsed Time since reset | Time since the total was reset | Read |
No points match these filters.
Object ID lookup: Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP point IDs by name
Integration notes
- The manual lists the objects as plain text (Analog Input 1 = Flow and so on) without units or access; all four are listed read-only here and units follow the meter's display settings.
- The ONICON F-5500 thermal mass flow sensor manual (DOC-0005059) prints the identical four objects; that meter reports ONICON's vendor ID 206 instead of Fox Thermal's 650.
- The AI 3 label "Total Flow / Reset Total" suggests the total can be reset, but the manual does not say how to do it over BACnet; the front-panel reset is described.
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 FT1 thermal mass flow meter, BACnet MS/TP and exports what it actually has to Excel — free.

Questions about the Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP
How many BACnet points does the Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP have?
This list has 4 BACnet objects: 4 analog inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP BACnet points are writable?
None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.
Where is the official Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP BACnet documentation?
The source is Model FT1 Fox Thermal Gas Mass Flow Meter - Instruction Manual (Document #106012 Rev M), published free by Fox Thermal at https://www.foxthermal.com/products/pdf/ft1/ft1-manual.pdf.
What are the minimum BACnet points to integrate the Fox Thermal FT1 thermal mass flow meter, BACnet MS/TP?
Start with AI 1 Flow (Gas flow rate); AI 3 Total Flow / Reset Total (Flow total since last reset); AI 2 Gas Temperature (Gas temperature).
How do I check these points on the real FT1 thermal mass flow meter, BACnet MS/TP?
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.
