Recommended Parts for Water Meth Injection setups

[RICE RACING]

Ah yep, we do supply pumps, filters, our own pressure control set ups and other parts, as well as do complete engineering work and integration of all kinds of water injection systems for people that require that, best is to send an email directly link below in signature.

Anyone know the wiring of this:
https://aquamist-direct.com/806-567-rep ... sor-cable/

It's a 4 wire hall effect sensor. I'm assuming:
Red to +5V
Yellow is signal to one of the freq inputs
Black and blue not sure - one is definitely ground, but what's the other one?

Hi all,

Please note the WMI will not accept or work with the Aquamist flow signal as its PFM not a PWM signal. That is directly from Richard L at Aquamist after trying to work out why we cant get his unit to work with the WMI controller.

Maybe Ryan can chime in when time allows but that is what I know so hopefully that helps others.

Interesting, was just about to start working on the WMI setup and have the Aquamist flow sensor. Is there a good alternative sensor for high pressures? Would be interesting to understand if there are chances of getting this working with PFM without HW changes to the WMI controller.

I've bought and wired for the Aquamist flow sensor based on Ryan telling me it was the sensor he used when developing the controller!?

Its been sorted now, will message you and others directly.

I’m about to wire in the flow sensor. Any info on how to do this so it works?

[nmerdan]

Also interested in the solution.

OK please see Ryans post here for latest firmware

We did have to open up a solder bridge on one customers unit but you will need to email Syvecs support please as its unit specific and just to be sure as I dont want to be saying do this when you may/may not need to do it.

Otherwise we have confirmed Aquamist flow sensor readings matching physical measures so all good now.

I can add some infos on the Aquamist sensor. I just tested one. It works with a Syvecs ECU.

Pinout:
1 red 5V Power supply
2 yellow Turbine Flow Sensor signal output 1mA max@5V
3 blue Feedback Signal (return ground)
4 black gnd

These are from a Aquamist paper, I can not confirm these:
0ml/min 0Hz
2500ml/min 400Hz

The output is an open collector frequency output, it needs a pullup to +5V. On a Syvecs set the input to "Thermistor".
Black and blue are bridged in the sensor. This is probably used by the Aquamist controller to check if the sensor is connected.
