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. Dfm-d-s7 hex.png

Teltonika FMB connection

Insert a SIM card and supply power to the TELTONIKA terminal.

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:

Alert.png NOTE: Configurator v1.6.4B.3.27 R2 or latest according to the firmware version.

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:

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.
