Measuring your engines fuel consumption and fuel flow has never been easier. A complete kit with digital gauge and dual flow meters so the engine's supply and return lines are monitored. The flow meters are in-line so fitting to your fuel hose is simple. Ideal for boats, yachts, generators, farm machinery and tractors, trucks and other vehicles.
Quality precision cut gear flow meters are ideal for vehicles, machinery, generators and boats / marine engine applications. This kit will allow users to monitor fuel flowing to the engine as well as the fuel returning to the tank plus so much more.
Accurate fuel monitoring allows the operator to adjust driving behaviour to achieve significant improvements in fuel economy. Optimising your engines performance can save thousands of dollars in fuel usage. These units are especially popular due to the range based calculations it can perform. Sometimes a small change in RPM can make a massive saving to your fuel usage and efficiency.
This kit has so many uses and functions users will be amazed what it can do.The primary function is to monitor fuel usage to provide a fuel consumption in L/hr. If you're running a diesel engine with a return line to the fuel tank,this kit will calculate the differential flow between the meters and calculate the consumption in L/hr.
You can also wire in your existing OEM or aftermarket fuel tank level sensor to display the fuel level in up to two tanks. If your fuel tank is odd shaped and not linear, you can perform a multipoint calibration with up to 6 points providing very accurate tank level displays.If you don't have a fuel tank sender, manually enter your fuel tank volume and let the display unit calculate the remaining fuel based on your consumption.
Enter your vehicle or crafts cruising speed and the display will calculate your range based on your instantaneous fuel consumption and remaining fuel. This input is quick and easy allowing for regular adjustments whilst underway as your cruising speed changes.
If you have a NMEA enabled RS232 GPS receiver this can be connected to display your fuel range based on your speed and remaining tank level.
The flow meters are precision cut from steel and aluminum, no plastic gears or paddles to fail. These meters are highly accurate, repeatable and suitable for use with diesel, biodiesel, unleaded petrol and many other fuels.Flow meters should be installed downstream of a filter to ensure fuel tank debris does not jam the meters internal gears. If the gears are jammed, they are easily accessible and serviceable using a Allen Key.
The display unit is a 2-1/4” sunlight readable LCD colour display designed for flush dash mounting. The display unit is not officially waterproof and installation should be within a cabin, wheelhouse or suitable weather proof enclosure. Whilst the display does not have a official IP rating for water and dust ingress, it has been built with an additional seal around the primary penetration being the rotary knob and the internal PCBs have been upgraded with conformal coating to prevent corrosion in marine environments.
Installation of this kit is straightforward and can be completed by those with an intermediate skill level. Installers should be confident in soldering wires for the electrical side. The mechanical installation of the flow meters involves cutting existing fuel lines and installing the inline flow meters with hose clamps over the barbed fittings.
A detailed instruction manual is supplied with the kit which covers all aspects of the installation and programming of the display unit.
What is not included:
Wiring to run between the flow meters and the display unit. Each meter has 3 wires which connect it to the head unit. 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.
Fittings: For the kits up to 4,000 LPH we can supply 1/4", 3/8", 1/2" and 1" hose tails in 316 Stainless Steel. Other sizes available on request. 5/16" fittings are available in brass. Please let us know which fittings you would like with your kit. We will match the threads so they screw straight into the flow meters you have requested!
|Flow Range||Inlet / Outlet 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|
Note, the following is a guide only. We strongly suggest you seek the advice of your engine manufacture when selecting the most suitable sized flow meters for your engine. We do not take responsibility if you select the wrong size kit although we will work with you to rectify.
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.
With the above in mind, let's consider a 200hp diesel engine which might be known to consume ~30L/hr at full RPM and ~10L/hr at idle. If we assume ~70% of the fuel sent to the engine is returned to the tank we can calculate the approximate flows in the supply and return line at different conditions.
30L/hr / 30% = 100L/hr to the engine normally.
100L/hr - 30L/hr = 70 L/hr returning to the tank at full RPM.
100L/hr - 10L/hr = 90 L/hr returning to the tank at idle.
For the above scenario one could consider flow meters which are ranged for flows between 5-150 L/hr or 20-300 L/hr as most suitable.
Users should query their engine manufacture for the fuel flow to the engine vs flow returning to the tank at idle and full load to be certain in their selection.
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. Using the same example above, a 200 hp petrol engine might be estimated to burn 10 L/hr at idle and 160 L/hr at full load. In this scenario one could consider the 20-300 L/hr range noting the accuracy of the meter when idling may not meet the tabulated 1% RS.
Scintex can supply the following hose tail fittings sizes for each flow meter. The ports are female BSP threaded and can accept many types of fittings if you wish to source your own. Each flow meter is supplied with 2 fittings, 1 for the inlet and 1 for the outlet.

|0.5-60LPH||1/4" Hose Tail||1/2" Hose Tail|
|5-150LPH||1/4" Hose Tail||1/2" Hose Tail|
|20-300LPH||3/8" Hose Tail||1/2" Hose Tail|
|50-800LPH||1/2" Hose Tail||3/4" Hose Tail|
|200-4,000LPH||1/2" Hose Tail||3/4" Hose Tail|
