One of the key functions of vessel telematics system – fuel monitoring – helps shipowners and vessel operators to reduce fuel and lubricants expenditures by 30-60%, allows implementing maintenance according to actual condition of vessels and, thereby, extend service life of fuel system.
DFM flow meters are integrated with the ship’s electronic systems over NMEA 2000 protocol.

Fuel flow meters for water transport
The best way to monitor fuel consumption of water transport − is to use direct fuel measurement tools, which provide precise fuel measurement no matter how intensive fuel “bounces” inside tanks/cisterns.
DFM fuel flow meters by Technoton are installed in fuel lines of each fuel consumer (engine, generator, boiler) and provide monitoring of fuel consumption and operating time of each fuel consumer individually.
One of the most important features of DFM flow meters is built-in battery and independence from external power supply, which makes it possible to use DFM on older boats with poor-quality electrical network, and on long-voyage ships, where a risk of flow meter disconnection from electrical network exists.
DFM and DFM D fuel flow meters for small and medium-sized vessels with fuel consumption from 1 to 600 l/h. Measurement inaccuracy is not more than 1%. Fuel counters are mainly used for river and sea-river ships. CAN j1939/S6 output interface allows monitoring 40+ Parameters of fuel consumption and engine operating time.
DFM Marine flow meters for heavy machinery are fuel counters for medium-sized vessels and large ships. Fuel flow meters measure flow rates up to 4,000 L/h with relative accuracy error of fuel measurement not more than ± 0.5%.
Flowmeter’s body is made of duralumin or brass − corrosion-resistant and highly durable material. Fuel line connection types – thread or flange.
DFM Industrial fuel flow meters – big flow meters for large ships with flow rates from 0.72 to 25 m3/h. Measurement inaccuracy is not higher than ± 0.5%. Fuel line connection types – thread or flange. Can be used for heavier grades of fuel (HFO heavy fuel oil or furnace oil) with kinematic viscosity up to 300 cSt.
In case there is a need for flow meters’ installation on large ships with many fuel consumers, all hardware is connected using S6 Technology – a unified cabling system, based on bus principle for data exchange and power supply of connected devices. Applying S6 Technology leads to reduction of labor intensity of installation thanks to connection of all on-board units by a single cable, and simplifies flow meters configuration.
Wireless DFM S7 fuel flow meter is a convenient solution for small and private fishing and pleasure boats. BLE flow meters do not require laying of power and signal cable; devices transmit data via Bluetooth 4.X. to telematics unit and/or to user’s smartphone and tablet simultaneously.
