Single-chamber fuel meter Eurosens Direct with a built-in microprocessor and anti-magnetic protection is used to measure fuel consumption of diesel engines, boilers, burners and other consumers in the range from 1 to 500 liters per hour.
Eurosens Direct provides not only fuel consumption in liters but also other important parameters as operation time and fuel consumption for different modes, tampering detection, etc.
Fuel flowmeter eurosens® Direct counts the amount of consumed diesel fuel and can be used both with vehicle tracking system and fuel monitoring system installed on the motor vehicles.
Eurosens Direct advantages :
- The set of Hall-effect sensors (instead of reed switch) provides magnetic immunity.
- Hard aluminum alloy with anti-friction coating.
- Versions with display to be used as stand-alone units.
- Temperature compensation to increase data accuracy.
- Digital interfaces RS485/MODBUS/CAN SAE J1939/simple pulse output.
- 2-year warranty without fuel flow limitation.

FUEL CONSUMPTION ADVANTAGES
- Made of hard aluminum alloy;
- Accurate measurement with temperature correction;
- Corrosion-resistant casing with sealed automobile connector integrated;
- Anti-friction coating;
- Strong electronic circuit protection;
- Magnetic-resistant due to Hall sensors used;
- Warranty term – 3 years, without fuel flow limitation;
- Smart software data processing;
- Deaerator will help to exclude air from the fuel system
Note : Most diesel engines have a fuel system with supply and fuel return lines. Thus, it is necessary to measure both fuel flows with Delta flowmeter, or change the fuel supply system for Direct flowmeter installation.

Flow meter index (100,250,500, etc) means the maximum fuel rate in the measuring chamber. It is the main parameter to choose the best suitable flow meter.
Q start – flow rate when fuel meter starts to measure Q min , Q max – Min and Max flow rate for range with declared precision In Direct PH flow meters Hall-sensors are used instead of a reed switch. It provides protection from the external magnetic field.
