SCINTEX Engine Fuel Flow & Consumption Kit is a complete kit with digital gauge and dual flow meters enabling monitoring of the engine's supply and return lines. The kit includes:
2 x Flow Meters
1 x Colour Display
Hose tail fittings and clamps included for kits up to 4,000 LPH (2 fittings for each flow meter to be specified at the time of ordering)
Instruction manual
Flow meters are provided for different flow ranges in liters and inlet / outlet port sizes:
Flow Range - Inlet / Outlet Port Size
0.5 - 60 LPH - 1/4" BSP Female
5 - 150 LPH - 1/4" BSP Female
20 - 300 LPH - 3/8" BSP Female
50 - 800 LPH - 1/2" BSP Female
200 - 4,000 LPH - 1" BSP Female
500 - 10,000 LPH - 1-1/2" BSP Female
Selection of the most suitable sized flow meters for your engine should be done in consultation with the engine manufacturer. Information for the fuel flow to the engine vs flow returning to the tank at idle and full load should be available for the selection of the appropriate flow meters. The following information is provided for guidance only and may differ for the intended application.
Diesel Engines
Diesel engines typically have a fuel supply line to the engine and a fuel return line to the tank. Whilst rare, some designs do loop the fuel return to the supply line, meaning you will only require a single flow meter in the common line from the tank. Fuel is typically supplied to the engine in excess to what is actually consumed and this is required to ensure the engine is not starved during peak demands, it also allows the fuel system to circulate and stay cool. Some engine manufactures report 50-85% of the supplied fuel to the engine is returned to the tank.
Petrol Engines
Petrol engines typically don't have a fuel return line back to the tank. Therefore selecting a flow range should be based on users understanding of fuel consumed at idle vs full load.
Hose tail fittings are supplied at different sizes for each flow meter. The ports are female BSP threaded and can accept many types of fittings. Each flow meter is supplied with 2 fittings, 1 for the inlet and 1 for the outlet. Fittings up to 1" are included in the price. For larger fittings contact us for a quote.
Flow Meter - Hose Tail (Minimum - Maximum in inches)
0.5-60LPH - 1/4"- 1/2"
5-150LPH - 1/4" -1/2"
20-300LPH - 3/8" - 1/2"
50-800LPH - 1/2" - 3/4"
200-4,000LPH - 3/4" - 1 1/4"
500-10,000LPH - 1" - 2"
For installation wiring between the flow meters and the display unit is required (not included). One of these wires is a 12v power supply which can be shared between the meters. Additionally the earth connection to the display unit can also be shared between the meters. An electrical wiring diagram is included in the user instructions.
SCINTEX Engine Fuel Flow & Consumption Kit is intended for use in vehicles, machinery, generators and boats / marine and other engine applications. The flow meters are precision cut from steel and aluminum and they are highly accurate, repeatable and suitable for use with diesel, biodiesel, unleaded petrol and other fuels. The display unit is a 1.8”, high resolution, sunlight readable, wide viewing angle, LCD colour display with a completely sealed and waterproof display front panel. The gauge enclosure is a common 52mm round size to fit many existing cutouts.
