Flowcat makes the SF45a which is also sold by Flowscan, and used by Flowscan in a number of marine and aircraft installations and is the only metal cased unit, I found. GEMS sells the FT110 & FT210 series which appear to be the Vision 2000 & Vision 1000 product lines, and Atlas Scientific sells the TurboFlow-226000. The Vision, Gems, & Atlas Scientific are Turbine flow meters and if the turbine wheel quits turning due to dirt they will still flow fuel. Where as most paddle wheel sensors stop passing fuel if the paddle wheel gets jammed by dirt also a lot of paddle wheel sensors have issues with stop & start fuel flow. The Flowcat unit is listed as being able to flow fuel if the mechanism is stopped from turning by the manufacturer I'm not sure if it's a turbine unit though. Also the turbine units are a lot less fussy about their mounting options.
The Futurelec FLOWFUEL30L0 {http://www.futurlec.com/FLOWFUEL30L0.shtml} also known as the Savant FS-3400AH {http://www.digisavant.com/Products.aspx?C=3&T=13} is at it's full rated flow on the supply side of my 1500 cc VW Rabbit @ 55mph. The engine in my Rabbit has less than 40000 miles on it since a complete overhaul including the fuel system.
The downside to the SF45a, GEMS FT110 & FT210 series, Vision 2000 & Vision 1000 and Atlas Scientific TurboFlow-226000 is they cost more than the paddle wheel models, but if the a paddle wheel stops turning due to dirt and the fuel flow to your engine suddenly stops it could cost you a lot of money and even a life. I've found the Gems models are available outside of the US for a semi reasonable price.

Thank you very much for yr opinion and knowledge.
However, maybe due to my limited English, I got confused of which ones of the fuel flow meters you prefer, and which is the type of metering they use.
For example, I loved the Futurlec fuel flow meter. However, I would need to add a second meter and a circuit to calculate the difference between them. But it may be a good kit to start working with. It is a pity they donīt say which is the mechanical method used.
Can you summarize which kind of meters you address and the ones you dont?
Again, thank you.
