Recently purchased a flow sensor FS-3400AH from Futurlec, specs are limited, 0.05-0.5 LPM with an open collector output. It's a 3 wire flow sensor (+/- and signal wire), compatible with gas/diesel, have manged to figure out that in order to generate a usable waveform the sensor signal output and pow...

I would start with the basic settings, take a pic with your phone an upload would be an option or just a shorten the recoding.

Ran into this quite a bit, can’t say for certain how to determine can overlaying but what we typically found was improper connection of aftermarket components, anything from scotch locks to removing termination resistors and tapping into the harness ends.

Thank you Steve, appreciate the breakdown of the capture.

Guess I’m missing it, your capture settings look Like the trigger did exactly as it was set up to do.

Not familiar with this engine but I would won’t to see the control side of the fuel rail pressure and verify upstream of the sensor is not influencing your trace, I would agree it appears that the signal is dropping out. Does it have any audible or visual indication of fuel pressure actually droppin...

I looked your codes up, much of what you have are CAN faults, your going to need a wiring diagram & scope or DVOM.

I would like to get input as to the capture in this case, T7 Inj Failure.pdf background is the machine had a fault code of 3067 injector 4 malf. engine had a definite misfire, the tech scoped the no. 1 & 4 injector (amp) and the ckp sensor Inj. 1 has a nice defined pattern, injector 4 has a similar ...

Heres what’s available in the states..

Not sure if they would ship internationally, or if it would be worth the money... could be better to make local like you mentioned.

Unless you are using the sensor reading as a measurement to a specification that is set by the manufacturer of the engine I don’t think a calculation is of any concern, reason being the pressure pulse sensor (regardless of brand) is used to help identify irregularities is pressure/vacuum pulse wavef...
