DFM diesel fuel flow meter is a single-chamber flow meter used for consumption measurement of the following fluids:
› Diesel fuel
› Heating oil
› Other liquid fuels and mineral oils with kinematic viscosity of 1.5 to 6 mm2/s.
DFM diesel flow meter is your tool for direct measurement of fuel consumption, which can be used as a part of GPS tracking system, vehicle telematics system or as an stand-alone (autonomous) solution for fuel consumption monitoring.
One-chamber DFM fuel flow meters are mainly intended for small and medium engines with indirect injection fuel system.
Typical Applications:
› Mining Equipment
› Concrete Trucks
› Dozers
› Diesel Locomotive
› Excavators
› Marine Vessels/ Boats/ Yachts (click here for a case study)
› Diesel Gen-Sets
Features:
› Preventing fuel theft
› Fuel consumption monitoring
› Engine testing for fuel consumption
› Machine running time tracking
Major Benefits:
› Digital Counters and built-in battery:-
All data is registered in digital Counters in internal memory of DFM fuel flowmeters. That ensures data safety and protection against tampering and interference by third party. Also, Counters are registering data even if external power supply is switched off. After the power supply is back all data is sent to telematics unit.
› Protection against tampering:-
DFM has two special Counters, which register third party influence attempts on flow meter operation – “Tampering” and “Interference” Counters.
“Interference” Counter protects DFM from magnetic field impact aimed on stopping fuel consumption measurement. “Tampering” Counter registers attempts of third party to tamper flow meter data by generating artificial fuel consumption (e.g. by blowing the air through measuring chamber).
In both situations DFM will start recording duration of influence and will send alarm to a telematics unit.
Online Monitoring & Control:
CAN j1939/S6 is a CAN (SAE J1939) based interface, which allows to create a network of smart sensors within one vehicle or stationary object. Major advantage of CAN j1939/S6 telematics interface is connection of all equipment (on-board units) by a single cable, which ensures power supply, configuration and data transfer to a telematics unit. Thus, CAN j1939/S6 grants possibility to save cabling space and reduce time needed for connection and configuration of equipment.
In vehicle telematics, CAN j1939/S6 is used for data collection from standard and additional equipment of vehicle, along with data gathering from one or several automotive CAN buses and its integration into vehicle telematics system.
