Fuel flow meter with electronic counter DFM
Simple solution for fuel monitoring
(1).png)
Purpose
DFM is a simple and easy-to-use fuel flow meter with electronic counter designed for measuring fuel consumption and operating time of vehicles, tractors, any mobile or fixed installations with diesel engines.
Fuel flow meter DFM is used independently, it means without any additional installation.
On the electronic display of the fuel flow meter is shown total fuel consumption, engine operating time in various engine power modes – idling, normal loading (optimal), overloading – and the other characteristics. DFM has no buttons, switching of indications is made with special contactless key.
Fuel flow meter DFM is protected from overstatement of readings and intervention.
DFM measures and displays:
- Instant fuel consumption, l/h
- Total fuel consumption, l
- "Overflow" counter, l
- Total engine operating time, h*
- Engine operating time in "Idle" mode, h*
- Engine operating time in "Optimal" mode, h*
- Engine operating time in "Oveloaded" mode, h*
* - these counters are accessible in MT version only.
Advantages
- Protection against unauthorized interference and tampering with the meter;
- Easy to mount and service;
- Big built-in fuel filter;
- Full set of mounting accessories;
- Engine working time control - total and in various modes;
- Reliable data transmission by the digital interfaces;
- Fuel flow meter DFM meets road standards of electromagnetic compatibility, mechanical and climatic influences;
- Resistant to vibration and hydraulic impacts;
- Automatic thermal compensation;
- Clear installation instructions, high quality technical support;
- Good price and discounts.
All the fuel flow meters DFM are tested on the metrologically certified installation.
Is it possible to deceive DFM?
It is recommended to seal pipes connections on the fuel flow meter output.
The unique function of overflow control will not allow to deceive the fuel flow meter. Even if unfair drivers try to blow the meter by air (it is usually the first that occurs), the fact of intervention will be registered.
Overflow control does not allow to make fuel discharges from return line.
Experiences in mounting DFM
We have a great experience in mounting fuel flow meters DFM. Fuel flow meter DFM can be installed on the following vehicles:
- Trucks;
- Tractive vehicles;
- Tractors of various types;
- Loaders;
- Graders;
- Road-building machinery;
- Technological transport;
- Fixed installations with diesel engines and etc.
Benefits
Fuel flow meter DFM enables to receive objective information about fuel consumption and vehicle operating time. It also allows lowering fuel and repairing costs and developing or checking fuel consumption rates.
Fuel rates are used to be excessive and record keeping of fuel consumption according to fixed fuel rates tends to increase operating expenses of the automotive fleet.
The economic effect of using the fuel flow meter is different at various companies, usually from 10 to 40%, depending on the baseline situation and management persistence.
Diesel flow meter DFM is an irreplaceable tool in conditions of permanent rise in prices for fuel and lubricants!
