6-71TIB's adding Maretron Flow meters

The larger ports I see are for much larger minimum flow, well above the level . If the unit is rated to flow up to 132 GPH how will the smaller port impede the operation- what am I missing? While I realize the hoses and a lot of the fittings are larger on the supply & return lines, however when you look at the actual orifices that some of the hose and fittings use to connect from the secondary filter to the engine, then from the engine to the fuel cooler those fittings appear to be small- maybe not 1/4" but still small.

OK, I wonder if the fuel pump on a 6-71 has enough pressure to push the flow I need to reach WOT going through that device. The flow reached on their website may be using an electric pump or one of higher capacity. I've now gone as far to ask technical support- what if after they are installed on my engines and I cannot make WOT after the install what will they do to support me. The fact that they cannot give me one example of these devices in an Detroit Diesel 6-71TIB installation is a cause for concern

attached is a photo of an install of Cat 3126- appears to have a higher fuel rate usage than my 6-71's?

I know my DD 6-71's flow 90 GPH at roughly 70-80 psi. I've asked Maretron for help, their reply was that they're not going to be responsible for a customers installation...

Question is how do you calculate the flow through a 1/4 inch orifice at 70 psi?

Also, I wanted to note the inverted flare fuel restriction orifice head inside the elbow fuel inlet is 1/4 x 5/16 NTP. This is the elbow that connects the fuel hose from the secondary filter to the engine. I found this example on Diesel pro.

So, choices are reduced with FloScan closing its doors:

Message body
It is with regret that I must inform you that FloScan will be closing its doors at the end of February. We have had a great 40-year run but the past few years have been difficult to maintain operations and profitability. We are currently taking final orders up until the end of this month. However, the FloScan model type and quantity that we can build and ship will be subject to availability. Lastly, we are in negotiations with a buyer to take over supplying spare parts and will advise once this matter is finalized.



We sincerely appreciate your business over the past 4 decades and wish you well.

yes, Responded off-line.

I installed floscans in my last boat, and was able to achieve very satisfactory results- the install manual was very straight forward.

From what I understand Maretron is the last best answer.
