Questions

·Why is the level gauge reading backwards?
AskWhy is the level gauge reading backwards?
Answer

        That means the gauge and the sending unit are using different standards (one may be using American
        standard, 240 ohm at empty, 30 ohms at full; the other may be using European standard, 0 ohms empty,
       180 ohms at full), hence, arenot compatible.
             Only solution would be to replace either the gauge or the sending unit so that both are using either
        European Standard or American Standard ohm range
.

·Does KUS carry a fuel sender that can be shortened in length?
AskDoes KUS carry a fuel sender that can be shortened in length?
Answer

      Yes, the length of the Capacitance Level Sensor (CLS) can be shortened in and signal output re-calibrator

·Are the level sensors or gauges NMEA 2000 certified or compatible?
AskAre the level sensors or gauges NMEA 2000 certified or compatible?
Answer

       Currently the gauges are not compatible with the NMEA 2000 system. The level sensors can be made
       compatible by connecting it to a signal converter module

·What are the signal outputs of the level sensors?
AskWhat are the signal outputs of the level sensors?
Answer

        The signal output for our sensors are 240-33 ohms (American Standard) &0~190 ohms (European
        Standard),or
current output, voltage output.
We can also customize output signal for customer, please

·How does the 2 wires from the sensors connect?
AskHow does the 2 wires from the sensors connect?
Answer
  •        Blue wire connects to the ground; black wire connects to the gauge. The sender draws power through
           the gauge connection
  • ·How do I determine the length of the sender I need?
    AskHow do I determine the length of the sender I need?
    Answer

           For Fuel/Water sensors, the length should be 1" less than the depth of the tank if tank is plastic, and
           0.5" less than the depth of the tank if tank is metal. This is to account for possible tank flex.

            For Grey/Black water holding tanks, the length should be 25% of the depth of the tank.

    ·What is the operating voltage for the sensors?
    AskWhat is the operating voltage for the sensors?
    Answer

             The sensors can work with both 12V and 24V system. The sender draws power through the gauge
             connection

    ·How to verify if sender is connected correctly?
    AskHow to verify if sender is connected correctly?
    Answer

           1. Check to see if the sending unit is receiving power from the gauge. The reading at the sending unit will
               be less than the input voltage at the gauge.

           2. Check the sending unit’s ground. The ground wire must be properly grounded to a common ground, or 
               to the negative on the battery.

    ·Do the sensors work only with KUS gauges?
    AskDo the sensors work only with KUS gauges?
    Answer

            No, the sender and sensors can work with gauges from other companies as long as both are compatible
           (both American standard units, or both European standard units)
