When it comes to tank monitoring, Maretron offers the most comprehensive NMEA 2000® technology in the industry. Whether you are looking to retrofit a tank with an existing resistive sensor, or if you're interested in precision tank level even when heeled over during sailing or riding bow up on plane, Maretron offers the right product for the application. All of Maretron's tank monitors can be custom calibrated for odd shaped tanks providing unprecedented accuracy, especially when compared to older analog gauge technologies. Maretron's tank monitors can even be programmed with the tank capacity so that multiple tanks can be combined into a single total tank gauge for display. You no longer have to mentally add up multiple tanks to figure how much water or fuel is onboard. And a real plus is that Maretron's user interface products will combine information from the tank monitors, fuel flow monitors, and GPS speed information to provide you with trip parameters like distance and time to empty. So look to Maretron for the widest variety of tank monitoring products and features in the industry.
