Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) BACnet points list
Updated 12 November 2026Unofficial source
The TFX Ultra is a clamp-on transit-time ultrasonic flow meter; energy models add two temperature inputs. On BACnet MS/TP it serves 11 analog inputs (signal strength, rate, three totalizers, both temperatures in °C and °F, flow in GPM and LPM) and a binary output that resets the totalizers.
This page lists 12 BACnet objects for the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Badger Meter’s documentation hosted by Instrumart, not by Badger Meter itself, so treat it as unofficial.

BMS integration notes: Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP)
Set the meter address (MS/TP MAC), baud rate and BACnet device ID from the keypad or UltraLink, then read the rate, the totalizers and (energy models) the temperatures.
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 |
|---|---|---|---|
| BO 1 | Reset Totalizers | Write 1 to reset all totalizers | Write |
| AI 2 | Flow Rate (Flow model) / Energy Rate (BTU model) | Flow rate (flow models) or energy rate (BTU models) | Read |
| AI 3 | Net Totalizer | Net total | Read |
| AI 16 | Flow Rate | Flow rate, GPM | Read |
| AI 11 | Temperature 1 | Temperature 1, °F (energy models) | Read |
| AI 12 | Temperature 2 | Temperature 2, °F (energy models) | Read |
| AI 1 | Signal Strength | Signal strength; low means poor coupling | Read |
Network setup
- ADDRESS (0-127) is the MS/TP MAC, BAUD the RS-485 rate, BACNET ID the device instance (0-4194303); set them in the BSC menu or with UltraLink.
- The PICS lists MS/TP master at 9600, 19200, 38400 and 76800 baud.
- Save the changes when leaving the menu; settings are kept in flash memory.
Watch out for
- BO 1 returns to inactive by itself after the reset.
Badger Meter Dynasonics TFX Ultra transit-time flow / energy 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.

Object ID lookup: Badger Meter TFX Ultra BACnet MS/TP point IDs by name
Integration notes
- The table gives a description and object ID only, with no Object_Name column; the description is used as the name here.
- AI 2 carries flow rate on flow models and energy rate on energy (BTU) models, in the units chosen in the meter. The MS/TP map has no unit-code objects.
- Instances are not contiguous (AI 1-7, 11, 12, 16, 17); they match the BACnet IP map numbering.
- Access is not printed per object; inputs are shown read-only and BO 1 writable as the notes describe.
- Source: Table 18 'BACnet MSTP object mappings', page 76 (12 objects).
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 Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP)
How many BACnet points does the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) have?
This list has 12 BACnet objects: 11 analog inputs, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) BACnet points are writable?
1 of the 12 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 Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP) BACnet documentation?
Badger Meter does not publish it on its own website. This list comes from TFX Ultra Flow and Energy Meters User Manual (TTM-UM-00136-EN-08), revision 2018-03, a copy hosted by Instrumart at https://core.instrumart.com/assets/Dynasonics-TFX-Ultra-manual.pdf. Ask Badger Meter or its representative for the current revision.
What are the minimum BACnet points to integrate the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet MS/TP)?
Start with BO 1 Reset Totalizers (Write 1 to reset all totalizers); AI 2 Flow Rate (Flow model) / Energy Rate (BTU model) (Flow rate (flow models) or energy rate (BTU models)); AI 3 Net Totalizer (Net total); AI 16 Flow Rate (Flow rate, GPM); AI 11 Temperature 1 (Temperature 1, °F (energy models)); AI 12 Temperature 2 (Temperature 2, °F (energy models)); AI 1 Signal Strength (Signal strength; low means poor coupling).
How do I check these points on the real Dynasonics TFX Ultra transit-time flow / energy 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.
