Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet IP Ethernet module) 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. With the Ethernet module set to BACnet IP it serves 25 analog inputs (signal strength, rate, totalizers, temperatures in °C and °F, flow in fixed units and the unit codes) and one binary output that resets the totalizers.
This page lists 26 BACnet objects for the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet IP Ethernet module) — 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 IP Ethernet module)
Order the meter with the Ethernet module, set the IP address and BACnet device ID on its web page, then read the rate, the totalizers and (energy models) the temperatures. Check AI 22-25 once to know the units of AI 2-5.
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.

|---|---|---|---|
| BO 1 | Reset Totalizers | Write 1 to reset all totalizers | Write |

Network setup
- IP address, subnet, gateway and BACnet device ID are set on the Ethernet module's web page, not from the meter keypad.
- Web page default address 192.168.0.100, reached with a crossover cable; it asks for a user name and password.
- UDP port 0xBAC0 (47808). Device object identifier is settable 1-9999 on the web page.
Watch out for
- The Ethernet module and the totalizer pulse output option cannot both be fitted on energy models.
- BO 1 returns to inactive by itself after the reset.

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
- 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; AI 22-25 report which units.
- AI 16-21 give the same flow rate in fixed units (GPM, LPM, CFH, CMH) and velocity (FPS, MPS).
- Access is not printed per object; inputs are shown read-only and BO 1 writable as the notes describe.
- The BACnet MS/TP version serves a shorter list (AI 1-7, 11, 12, 16, 17 and BO 1).
- Source: Table 17 'BACnet IP object mappings', page 75 (26 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 IP Ethernet module) and exports what it actually has to Excel — free.

Questions about the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet IP Ethernet module)
How many BACnet points does the Badger Meter Dynasonics TFX Ultra transit-time flow / energy meter (BACnet IP Ethernet module) have?
This list has 26 BACnet objects: 25 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 IP Ethernet module) BACnet points are writable?
1 of the 26 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 IP Ethernet module) 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 IP Ethernet module)?
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, units per AI 23/24); 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 IP Ethernet module)?
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.
