However... The Kickstarter campaign had an end date of January, 2016. The goal was not met. The estimated price, $250CA, appears to be for ONE sensor. Most diesels need two. I have two diesels. The second (return) sensor was reported to be only in the planning stages (back in 2015.) The page suggests they're going to use low-energy Bluetooth. Not suitable for communicating from ER to flybridge. The page suggests the units are battery-powered. What, no 12V available in your ER??? Some other module would be needed to get this data onto an existing N2K bus, or into a NMEA 0183 MFD, if that's even possible. It appears this company wants to build it's own competing network based off an iPhone app and Bluetooth. They now have an order page at their web site (linked from the Kickstarter page), and I don't see any indication that any of this has changed. I see flow meters in industrial settings for far less money. Every vehicle on the road has dozens of sensors that interface with CANBus, which is very similar to N2K. A lower-cost alternative to FloScan seems very achievable. Except that the manufacturers see $$$ when they hear the word "marine." - Tom
