Differential fuel flowmeter Eurosens Delta is used to measure the fuel consumption of diesel engine. Most engines have supply and return line. To obtain fuel consumption of 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.

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 credibility of the results, that are independent of fuel composition, tank form and operating conditions. It is very a important issue – fuel monitoring system must be accurate and thrustworthy otherwise it is useless.

Delta flow meters have a wide list of modifications, you can see them at PRODUCT SPEC tab.

Note:

Differential method of measurement does high demands to flow meter precision. It is because flow rates in supply and return line usually are much bigger than engine fuel consumption.

For example, for 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 result at idling we need to measure both fuel flows with precision no more than 0.3%. Moreover, temperature expansion of fuel (0.7% per every 10 Celsius degrees) add extra error to differential measurement, because temperature of fuel coming to engine and returning to tank is differ.

That means, you can’t use idea of 2 separate flow meters without good precision and temperature correction.

Fuel flow meters Delta are made from hard aluminium alloy, measuring chambers have antifriction coating, in both measuring chambers fuel temperature sensor is installed. Each manufactured flow meter is pre-calibrated for differential application. Thereby Delta flow meters can provide accurate results in any mode of engine operation.

Unlike some other manufacturers, Delta flow meter warranty not limited by passed flow. 3 year without flow limitations.
