Description
Mechatronics Eurosens Delta Fuel Flow Meters are used to measure the fuel consumption of diesel engines. Most engines have supply and return lines. To obtain the fuel consumption of the engine it is necessary to measure both fuel flows and calculate the difference. This task looks not easy but with Eurosens Delta you can receive accurate results immediately after the installation without any calibration.
Fuel flow meters Eurosens Delta are made from hard aluminum alloy. The measuring chambers of Eurosens Delta have an anti-friction coating, and in both chambers, there is a fuel temperature sensor installed. Delta flowmeters are pre-calibrated for differential application. Thereby Delta flowmeters can provide accurate results in any mode of engine operation.

Advantages
- High-precision measurement
- High corrosion resistance
- Strong electronic circuit protection
- Sealed automobile connector on the sensor body
- Indication lights provide an easy understanding of the device’s state
In what cases a differential fuel flowmeter is the best choice for fuel consumption monitoring – you can read there. Of course, Delta flow meters can be used in other applications too. In comparison with fuel level sensors, fuel flowmeters are much better in the credibility of the results, which are independent of fuel composition, tank form, and operating conditions.
It is very a important issue – the fuel monitoring system must be accurate and trustworthy otherwise it is useless. Delta flow meters have a wide list of modifications, you can see them in the SPECIFICATION tab. Eurosens Delta advantages for installers
- Special free diagnostic software
- Software function of flow direction reverse
- Smart software processing of fuel flow pulses allows for avoiding the use of check valves. It minimizes the hydraulic resistance of the system and very important factor.
- High-quality measuring chambers
- Warranty term – 3 years, without limitation of passing flow.
- You can use a specially designed Deaerator device to remove air from the fuel system.
Note: Differential method of measurement does high demands to flow meter precision. It is because flow rates in supply and return lines usually are much bigger than engine fuel consumption. For example, for a John Deere tractor, at idling in fuel supply line – 200 liters/hour, in return line – 197 liters/hour. Engine consumption – 3 liters/hour. That means that for adequate results at idling we need to measure both fuel’s flow with a precision of no more than 0.3%.
Moreover, the temperature expansion of fuel (0.7% per every 10 Celsius degrees) adds extra error to differential measurement, because the temperature of fuel coming to the engine and returning to the tank is different. That means you can’t use the idea of 2 separate flowmeters without good precision and temperature correction. Fuel flow meters Delta are made from hard aluminum alloy, measuring chambers have an antifriction coating, and in both measuring chambers fuel temperature sensor is installed. Each manufactured flowmeter is pre-calibrated for differential application.
Thereby Delta flowmeters can provide accurate results in any mode of engine operation. Unlike some other manufacturers, Delta flowmeter warranty is not limited by passing flow. 3 years without flow limitations.
