Technoton DFM D S7 Differential Fuel Flow Meter
Introduction to the product
DFM D S7 Differential and DFM S7 Fuel Flow Meter connected to FMB using the Bluetooth interface.
Declaration of Compatibility
DFM (D) S7 Differential Fuel Flow Meter connection
Switch the DFM S7 flowmeter to the operating mode according to the operating instructions.
To obtain the MAC address of the DFM (D) S7 flowmeter, you need to transfer the sensor number from decimal to hexadecimal code.
Teltonika FMB connection
Insert a SIM card and supply power to the TELTONIKA terminal.

NOTE: Firmware 03.27.01 Rev:00 or latest. |
Terminal configuration and fuel level sensor calibration
Terminal settings in the Configurator
Configure the GPRS data of the SIM card operator and the address of the telematic server:
| |
NOTE: Configurator v1.6.4B.3.27 R2 or latest according to the firmware version. |
Choose the protocol as shown below:
Connection of the Differential Fuel Flow Meter to the terminal
Put the sensors near the terminal.
Make ‘Discovering’ of the sensors:
In DFM D S7, data is transferred in 4 PGNs (messages).
In DFM S7, data is transferred in 3 PGNs (messages).
Since only 1 PGN can be configured in one connection (Connection 1), to receive all data from the fuel flow meter we use all four connections with the same MAC address (Connection 1, Connection 2, Connection3, Connection 4 (only DFM D S7)).
Write down the MAC address of the sensor in the settings field and select the PGN settings:
Data from the DFM (D) S7 flowmeter are displayed in the configurator. Press the Low button to select the parameter to be sent to the server:

Displaying data on a telematic server
Register the terminal on the telematics server.
The data on the server looks like this:
Sensors configuration

An example of setting the fuel consumption per hour on the server:
In the case of using several sensors, it is necessary to limit the number of transmitted messages (PGN).
4 PGNs are available for configuring at any MAC addresses.
