Design Guidelines Flow sensors are accurate measurement devices, which need some considerations in design and care during installation. Any measuring sensorcan only perform in the optimum range, when it is used within it’s specific requirements. Please consider application specific limit values.

Negative influencing factorsList of factors which can influence the performance of the flow meter negatively

Further we want to give some consideration for the whole fuel pipe installation:

Direct measurement of consumption for totalizing fuel consumption

Differential measurement of consumption for real-time and totalizing of fuel consumption

Medium� Seawater� Acid� Cleaning products

Mechanical� Pulsating pressure� Cat fines� Pre-Filter mesh size

Specification� Dimension to small� Over temperature

Temperature and density compensationIf fuel oil consumption is compared in mass instead of volume, it is important to know the exact density which is affected by the temperature, hence it's essential toinstall temperature sensors close to the flow meter. Depending on the process it can be around 1% difference in consumption per 10°C temperature difference.Aquametro recommends to have a density sensor installed to measure it online. If no sensor is available, density values of the bunker report can be used.

Sample calculation for differential measurement

ASSUMPTION:Standard calibration 1 % accuracy (CONTOIL® VZF):� Supply (FM#0) 10’000 l/h ±1 % = ±100 l/h� Return (FM#1) 10’000 l/h ±1 % = ±100 l/h� Max. difference 2 % = 200 l/h

ASSUMPTION:pair calibration 0.1 % & 0.3 % accuracy (CONTOIL® VZFA):� Supply (FM#0) 10’000 l/h ± 0.1 % = ±10 l/h� Return (FM#1) 10’000 l/h ± 0.3 % = ±30 l/h� Max. difference 0.4 % = 40 l/h

Offset and differential measurementWith Aquametro Fuel Performance Management Systems like: Fuel Performance Recorder (FPR), CONTOIL® Fuel Monitor-S (CFM-S), CONTOIL® Fuel Monitor-T(CFM-T), these compensation calculations are done automatically, according to DIN 51757.

Sample calculation with direct and differential measurement

ASSUMPTIONS:� All Flow meter 1 % accuracy� M/E consumption 4’000 l/hr� A/E SL: 3000l/hr; RL: 2600l/hr� Circulation pump 10’000 l/hr

� Accuracy M/E with A/E running� FM2: 1 % of 3’000 l/hr � 30 l/hr� FM3: 1 % of 2’600 l/hr � 26 l/hr

� 30 + 26 l/hr = 56 l/hr of 400 l/hr � A/E consumption 14 % error� FM0: 1 % of 4’000 + 400 l/hr ➩ 44 l/hr� Total accuracy of M/E = 44 + 56 = 100 l/hr of 4000 l/hr � M/E consumption 2,5 % error

Sample calculation with 2x differential measurement

ASSUMPTIONS:� All Flow meter calibrated in pair: (0.1 % / 0.3 accuracy)� M/E SL: 10’000 l/hr; RL: 6’000 l/hr� A/E SL: 3'000 l/hr; RL: 2'600 l/hr

� Accuracy M/E with A/E running� FM2: 0.1% of 3’000 l/hr � 3.0 l/hr� FM3: 0.3% of 2’600 l/hr � 7.8 l/hr� 3.0 + 7.8 l/hr = 10.8 l/hr of 400 l/hr � A/E consumption 2.7 % error

� FM0: 0.1% of 10’000 l/hr à � 10.0 l/hr� FM1: 0.3% of 6’000 l/hr à � 18.0 l/hr� Total accuracy of M/E=10+18=28l/hr of 4’000 l/hr � M/E consumption 0.7 % error
