Cheat protection features. In order to avoid cheating of flow sensor, its damage or blocking Delta and Direct PN, RS models has the following modes of protection against cheating actions of third parties: 1) Mode "Cheat" ‐ protection against cheating in order to increase the counter value of the consumed fuel (eg. air blowing). Cheat usually leads to a rapid increase in fuel consumption that exceeds the maximum one. Electronic circuit board of a flow sensor detects overstated costs, while fuel meter operation is stopped and counter "Cheat" is activated, which records the amount of fuel flown through the flow sensor at high speed. Mode "Cheat" is automatically exited in few seconds after the normalization of conditions of flow sensor work. www.mechatronics.by Page 12 | 30 ...
Page 13
2) Mode "Intervention" ‐ under the influence of an external magnetic field, the flow sensor detects an attempt to interfere and as the result the sensor itself is operating in standard mode and the exposure time is recorded in a special counter "Intervention time." Mode “Intervention” is automatically exited in few seconds after the end of attempts to interfere. 3) Sealing of connections ‐ mounting accessories (fuel connectors, clamps, etc.) supplied by JSC Mechatronics have holes for sealing, that allows to determine the facts of unauthorized interference in the fuel system after the installation of the flow sensor. 2.8.5. Characteristics of the pulse signal of Eurosens Flow meter with non‐standard pulse (model P) has an output pulse signal shown in Fig.2. For each flow meter the number of pulses generated by flowing of 1 liter of fuel through the measuring chamber is shown in the data sheet for the product (passport). ...

• Service kit Eurosens Destination • PC • mounting kit (sold separately); • Hand tools (wrenches, screwdrivers). The flow sensor can be mounted in any position: vertically, horizontally or inclined. Do not kink the cable and fuel pipes (fuel supply lines). It is recommended to mount the sensor www.mechatronics.by Page 17 | 30 ...
13. Do not use flowmeter with maximum flow rate lower than the actual one on the equipped vehicle or diesel generator. 14. It is not recommended to use internal or external filters with petrol gauze (the cell area is less than 0.6 microns) in the wiring scheme. There could be failures in work of fuel system at subzero temperatures. 4.4. Installation schemes of Eurosens fuel flow meters 4.4.1. Typical fuel supply system The most common scheme of the fuel system of diesel engine is shown on the Fig.4. www.mechatronics.by Page 18 | 30 ...
Page 19
EUROSENS Fuel flow meters. Operation manual. ver. 1.6 Fig.4. Typical fuel system Fuel backup pump (hereinafter – supply pump) supplies to the inlet of fuel injection pump (hereinafter ‐ fuel pump) significantly larger amount of fuel than is consumed in each cycle of operation of the engine. Excess fuel from the fuel pump and injectors of the engine is discharged back into the tank through relief valve. 4.4.2 Installation of fuel flow meters Eurosens Direct "On pressure side" scheme Installation of fuel flow sensor Eurosens Direct "On pressure side" scheme intends the installation of a flow sensor between fuel fine filter and fuel pump, where fuel is flown under pressure. Fig.5. Eurosens Direct installation «On pressure side». Check valve is necessary only for “Direct P, PH” series. www.mechatronics.by Page 19 | 30 ...
Page 20
Advantages of the scheme "on pressure side": • Eurosens Direct is set after the regular fuel fine filter; • Reduced flow resistance on the supply pump suction side. • Return flow heats fuel in the tank. Disadvantages of the scheme "on pressure side": • cooling of fuel pump decreases a little; • return line temperature is lower than in the standard fuel scheme. 4.4.3 Installation of Eurosens fuel flow meter under "suction scheme" Installation of fuel meter "on suction side" supposes the installation of a flow sensor in the area of the fuel system, where the fuel flow is forced by suction created by supply pump. WARNING! Installation of Eurosens Direct flow meter "on suction side" requires an additional fuel filter on the fuel line from the tank to the flow sensor. A special case of Direct flow meter installation under "suction scheme": To install the Direct under scheme "on suction" in the engine fuel system with fuel backup pump (see. Fig.6), it is necessary to use the site between the fuel pre‐filter and the inlet of fuel backup pump. www.mechatronics.by Page 20 | 30 ...

To prevent measuring the volume of fuel returned to the fuel tank it is necessary to change the circuit return line. For this special case, it is necessary to change the fuel pump return line so that the fuel is circulated in a small circle without return to the fuel tank. This is done by connecting the return to the input of the fuel supply pump. Thus, to the inlet of supply pump two lines are connected: 1) supply from the tank, passing through the flow sensor; 2) The return fuel pump. Thus, through the flow sensor Direct goes only the amount of fuel which is consumed by the engine. WARNING! One of the advantages of fuel return to the tank through the fuel line is heating the rest of fuel in the tank. Therefore, if vehicles work at low temperatures it is recommended not to change the scheme of the fuel but to use differential flow sensor Delta, or install extra fuel heater. To install Eurosens Direct "on suction side" in the engine fuel system without the fuel supply pump (see. Fig.7), it is necessary to place the flow meter between the fuel pre‐filter and the fuel pump bypass valve. At the same time, an additional fine filter in the area between the place of installation of the flow sensor and the pre‐filter should be installed. www.mechatronics.by Page 21 | 30 ...
Page 22
Disadvantages of the scheme "under suction": additional fuel fine filter is needed, that increases the cost of installation; increased pressure on the fuel pump the fuel in the tank isn’t heated by the fuel from the return line (sometimes it is needed to install an additional heater) 4.4.4 Installation of Eurosens Delta under "Differential" scheme In differential scheme the measuring circuit of fuel circulating in the fuel system is not changed. Supply chamber of Delta sensor is installed in fuel supply line, return chamber – in return line. Fuel consumption is thus determined as the difference between the measured values of flows in the supply and return cambers. Particular cases of Delta installation under differential scheme: 1) The supply chamber is installed in the fuel line after supply pump and fine fuel filter (on pressure side). See Fig.8. 2) Supply chamber is installed in the fuel line before supply pump (on suction side). In this case, the installation of an additional fine filter is necessary (see. Fig.9). www.mechatronics.by Page 22 | 30 ...
