Re: Navman 2100 gauge vertical installation anyone?
Hi,<br />The instrument itself can me mounted in any position - it is all digital and there is no fuel house passing trough the instrument. There is en electrical wire from fuel flow sender to the instrument.<br />The flow sender use an infrared beam to count the revolutions of the turbine blades as they spin which then sends a pulse signal to the computer/instrument (see Navman FAQ on Fuel computers).<br />See the Navman Manuals available in PDF on their homepage for additional mounting requiremnets, for example:<br /><br />"Choose a location for the display unit that:<br />- is easily seen and protected from damage<br />- is at least 100 mm (4") from a compass<br />and at least 500 mm (19.5") from a radio or radar antenna <br />- is away from engines, fluorescent lights, power inverters and radio or radar transmitters<br />- is accessible from the back; a minimum clearance of 50 mm (2") is required at the back (see mounting diagram) <br />- protects the back of the unit from moisture and water."<br /><br /><br />It is the fuel flow sender (flow meter) that is mounted on the fuel line that should be mounted vertical to avoid air in the fuel adhering to the turbine blades, which effects accuracy.<br /><br />I have the Navman 3100 (suitable for gas singel engine or dual engines, inboard or outboard). I use it with my Yamaha F115.<br /><br />Make sure You meet the system requirements for using a Navman Fuel 2100. Read on Navman homepage and in the Manual You can download in PDF from Navman homepage.<br /><br />Do You have one or two tank(s)?<br />If You have one tank only but two instruments - how will you know fuel used and fuel remaining without doing some manual calculation?<br />Why not get the Fuel 3100 instead? One instrument for dual engines (and singel or dual tanks). Check the Navman Fuel 3100 manual on Navman homepage.<br /><br />Remember to calibrate the Navman instrument with a known exact amount of fuel so it will be accurate.<br /><br />My installation of the Fuel 3100 (the lower of the two large instruments to the right, the upper instrument is a Navman Depth 3100 instrument):<br /><br />
