MeterMatch
™
Overview
The MeterMatch™ by Tanks, Inc. 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. In addition, it allows you to have low and/or high set-
points that will trigger a bright, blinking LED indicator to alert if the
gauge exceeds normal values.
Theory of Operation
MeterMatch is wired between your sender (sensor) and your gauge. It reads the resistance of the
sender, then based on the calibration values, works as an electronic resistor to drive your gauge to
the desired reading. It treats the input and output entirely separately, so it doesn't care if the input to
the gauge is scaled differently than the sender, or even if the sender signal is reversed - it can correct
for that. In the graphic above, prior to installation the green lines would be connected together.
MeterMatch interrupts that signal to process it and make corrections. Note that the wire terminals are
physically not arranged in this same order – it is shown this way for clarity.
