5 2. SYSTEM DESCRIPTION The Fuel Consumption Monitor (FCM) is a microprocessor based instrument that will accurately calculate the fuel consumption of the engines onboard a vessel. In this manual we assume that the installation consists out of one main engine and auxiliary engine(s). Many other configurations are possible. In order for the FCM to work accurately it will need flow and temperature data from 3 flow meters with PT100. A. Flow meter, supply to aux engine B. Flow meter, return from aux engine C. Flow meter, common supply fuel system However, there is an option to switch the temperature correction off. Please note that with the temperature correction off, the amounts of fuel will not be corrected for temperature and therefore will not be accurate. To calculate the consumption per nautical mile, the FCM will need the ship speed information either from a GPS unit or from a ship speed unit that has pulses as an output. 3.

12 7. OPERATING INSTRUCTIONS 7.1 GENERAL The FCM will accurately calculate the fuel consumption of 2 Engines. The names chosen for the Engines are Main Engine (ME) and Auxiliary Engine (AE). The flow meters are called A, B and C. Flow meter A: Supply Auxiliary engine. Flow meter B: Return Auxiliary engine. Flow meter C: Supply total system. Please refer to figure-1 for the correct location of the flow meters. The FCM will measure the total fuel delivered to both engines and the flow to and from the Auxiliary engine. For accurate calculation, the temperature of the fluids are needed from each flow meter. From the flow and temperature information of the three flow meters the fuel consumption of the ME and the AE is calculated as well as the total consumption, per minute. In combination with the speed of the vessel a consumption per Nautical Mile is calculated. On Main Screen 1 you will see the calculated consumption of the ME, AE and the total, with and without temperature correction (T.C.). The consumption with T.C. will be displayed in volume(l or m 3 ) and mass (kg or ton) per minute. Main Screen 2 will give more details about the AE. Main Screen 3 will give more details about the ME Important settings For correct calculation of the fuel consumption, it is important that the parameters as in Chapter 7.10 are set correctly. Typical customer settings that have an influence on the results, with our standard settings are: Temperature correction on Specific gravity at reference temperature 0,997 kg/l Thermal coefficient of expansion 0,070 %/ C Reference temperature 15 C Formulas For the calculation of the displayed fuel consumption, the following formulas are used: Consumption AE AE = flow A flow B [l/min] Consumption ME ME = flow C (flow A flow B) [l/min] For the calculation of the displayed temeparture corrected fuel consumption, the following formulas should be applied to the flowrate: Temperature difference T = T T ref [ C] Expansion γ Tot = γ * T [%] 11

13 Flowrate temperature corrected Qcor V = Q V / (1 + γ Tot /100) [l/min] Massa flowrate Q M = Qcor V * ρ [kg/min] Example calculation With above mentioned standard settings, the following flowrates are assumed for example calculation: Flow C 97,2 l/min 91,1 C Flow A 45,3 l/min 132,4 C Flow B 32,5 l/min 128,3 C Uncorrected consumption: AE = 45,3 32,5 = 12,8 l/min ME = 97,2 (45,3 32,5) = 84,4 l/min Flowrates calculated back to reference temperature: Flow C = 97,2 / (1 + 0,07 * (91,1 15) / 100) = 92,3 l/min Flow A = 45,3 / (1 + 0,07 * (132,4 15) / 100) = 41,9 l/min Flow B = 32,5 / (1 + 0,07 * (128,3 15) / 100) = 30,1 l/min Temperature corrected consumption: AE = 41,9 30,1 = 11,8 l/min ME = 92,3 (41,9 30,1) = 80,5 l/min AE = 11,8 * 0,997 = 11,8 kg/min ME = 80,5 * 0,997 = 80,3 kg/min Temperature compensation and accuracy of results Fuel consumption measurement in return systems In so called return systems, it is necessary to have two flowmeters installed in the system: one in the fuel supply line and one in the fuel return line. When measuring with two flow meters in such a return system it is absolutely necessary to have temperature compensation on the measured flow, since a different temperature will mean that the flowmeters will indicate a different volume flow. The error introduced when not compensating for temperature will be almost 1% per 10 C temperature difference. Due to the fact that the circulation will be x times the consumption, this means that the error will be multiplied by x, when compared with the consumption. Unifuel The same phenomenon occurs in so called unifuel systems, in which the total supply to the systems is measured by a flowmeter in the cold part of the system ( common flow ). The hot system is split after the viscosity control into a circulation over the main engine and a circulation over the auxiliary engine(s). The consumption of the auxiliary engines is measured by flowmeters in both the supply and the return line. The consumption of the main engine can be obtained by subtracting the auxiliary consumption from the total consumption: ME consumption = common flow (supply AE return AE). Due to large temperature differences between cold part (approx. 70 C) and hot part (approx. 145 C), it is also in this case very important that all three measurements are compensated for temperature, as otherwise large errors might be introduced (see above calculation) 12

14 Multiplication of error Due to the fact that in return systems the fuel consumption is small when compared to the circulation flow, this means that every error that is made in measuring flow or for not compensating for temperature, the error per flowmeter will be multiplied by the circulation factor when compared with the consumption. 7.2 DISPLAY The display has the following screens: Screen 1: Main screen 1 Screen 2: Main screen 2 (auxiliary engine and total consumption) Screen 3: Main screen 3 (main engine and total consumption) Screen 4: Alarm screens Screen 5: History screen main engine Screen 6: History screen auxiliary engine Screen 7: History screen total Screen 8 Set up Screen 9 Actual flows and temperatues Screen 10: General settings Screen 11: Configuration flowmeters Screen 12: Configurations ship speed Screen 13: Configurations range output Screen 14: Time and Date (for alarm log) Screen 15: Contrast LCD 13

31 7.17 FORMULAS Fuel consumption: Auxiliary engine: flow A flow B Main engine: flow C (flow A flow B) Average: The average is calculated as follows: Every second a sample is taken from all input signals. Per minute the average of 60 samples is calculated. From these values a hourly average is calculated. E.g. if the timeline is 24 hours, a value is shown that is the average over the time past since the start. If the time has passed, the average calculation will start over again. Example: Every second: 45, 46, 44, 42, 41, 44,, 51, 49 after 1 minute 46 is recorded (46 on screen). 45, 44, 43, 40, 41, 42,, 50, 41 after 1 minute 44 is recorded (45 on screen). 45, 44, 43, 39, 41, 42,, 26, 29 after 1 minute 40 is recorded (41 on screen). E.g. after 60 minutes 43 is recorded. After 60 minutes 41 is recorded. After 2 hours and 3 minutes: (60x x ) / 123 = 42. After 24 hours all stored values are deleted and the calculations will start again. As an option the time period over which the calculation has taken place is show on screen.
