DFM is designed for fuel consumption measurement in fuel lines of vehicles and stationary machines, also for operating time monitoring in different working modes of engine. DFM fuel flow meter is 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 is a tool for direct measurement of fuel consumption, which is 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. 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 cheating 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.
