This thread a due for an update...
Aquamist is the first to develop a turbine flow sensor to read flow in real time in 2001. A good few years late, other companies followed with varied success. It was most probably using an off-the-shelf plastic body sensor in harsh engine bay environment. Over the next few years, every wmi makers settled on the turbine wheel type instead of the paddle wheel type due to cost. But still plastic body based whilst aquamist continue to employ the metal type. Totally reliability.
Fast forward this to 2013 and after some serious research, a couple of wmi manufactures have stopped offering the plastic flow sensor all together (supplied by GEMsensors.com) and used some alternative methods to detect flow problems. The messages was loud and clear to other wmi makers. These sensors just continued to fail in service, some just after a few months. Whilst this was going on, the aquamist's in house designed and manufactured sensors continue to perform flawlessly.
The most surprising outcome to this is the way the some wmi makers changed the way of marketing the same old sensor. Instead of sourcing a more reliable one, they just tell their customers to reduce the methanol concentration to 50% for safety reasons (wise words indeed) while still marketing their product as methanol injection systems. Unfortunately those sensors continued to be unreliable even after methanol ratio was reduced. There are hundreds of engines at risk out there without a failsafe due to flow sensor failure.
It is a real irony that a failsafe is the first item to fail...
