Water and Fuel Gauge Calibration

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Our 460 has a SIMARINE Nereide electrical switching panel with useful information but the water and fuel levels are significantly out of calibration with real measures. For example water was showing 54% but it only took 105 litres to refill to 100%. Dealer has not been able to resolve the issue so does anyone know the solution please?We also have low charging on the USB ports in the berths- I phones drop off charge every 10 minutes- not good for anchor watch. Small problems but quite important.

	Depends on how long is the transducer in the tank. If the probe doesnt go close to the bottom of the tank then it cannot be accurate. You can either change it or see how much water you still have when it shows empty.

	Regarding the calibration of the fuel level, this has been discussed several times already, one solution is to make a table of the actual amount of fuel vs the reading: 1 have the tank completely empty, 2 fill exactly 1 gal at the pump ( or whatever step you prefer), record the reading, continue 1 and 2 with the same step until the tank is full. For the USB port not charging, I would first check/replace the charging cable, it's a most common problem with such symptom.
