Permanent fuel flow consumption monitoring of boat engine is an important task. First reason to install the fuel meter is unpredictable fuel consumption that depends from waves. In fact boat does always climbing and descending the sizable waves was the equivalent of adding many miles to the trip out and the result was the boat burned almost twice as much fuel as it would have under calmer sea conditions.

The unpleasant situation and the costs associated with running out of fuel could have been avoided if you have fuel flow meter installed onboard. You will know that fuel consumption rate on the way out was far greater than normal and taken appropriate action to prevent running dry long before you will have run out of fuel.

Second reason is that fuel flow meter will help you operate your boat more efficiently, the liters (gallons)-per-hour being burned at any speed while underway. That simple bit of data can save enough fuel that the flow meter will pay for itself in a short time and, if you’re like me, you might be surprised to find that your boat actually operates more economically at a higher cruising speed.

Next reason is diagnostic feature. Fluctuations in fuel consumption can talk about clogged fuel injector or air filter.

Mechatronics provide unique differential type fuel flow meters Eurosens Delta. Why we need the differential-type fuel meter?

Because diesel engine usually has both supply and return fuel lines. And fuel consumption is difference between fuel flow rate in this lines.

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.
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 flometers 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 flowmeter is pre-calibrated for differential application. Thereby Delta flowmeters can provide accurate results in any mode of engine operation.
