Convert any ohm range fuel level sender to work with any ohm range fuel gauge! The MeterMatch TM is for making analog gauges more accurate or to allow you to mix and match different gauges and senders. It can be used with many gauges that have resistive senders - such as common fuel oil-pressure and temperature gauges. It also allows you to have a low and/or high set points that can trigger a blinking LED indicator to alert if the gauge exceeds normal values.Features:User can calibrate a custom ohm range (0-3000 Ohms) The gauge can be calibrated at empty full and two other points ensuring accurate readings even with odd shaped gas tanksThe interface is compatible with nearly any short sweep fuel gauge and fuel sender combination Easy screw terminal wire connections Compact size 2.4" x 1
