Matches senders to gauges, even reversed ones!

Works on most senders and gauges

Can compensate for reverse gauge, reading low, reading high,

adjustable Anti-Slosh and two-stage Low Fuel


0-5V output for calibrating when not used with a gauge. ( Firmware 4.5 only)



This electronic circuit design:



Allows virtually any resistive sender to work with virtually any Gauge. (petrol, diesel, LPG, water etc.)

Requires a +12 Volts supply (negative earth)

With 5 calibration points, it can cope with non-linear senders and gauges as well as oddly shaped tanks

Has adjustable Anti-Slosh (responds slowly to input changes )

Two-stage (steady and flash) fully adjustable low fuel warning (or high temperature etc.) light output capable of driving standard bulbs or LEDs



This wizard can be calibrated for sensors and gauges between 0 and 1000 Ohms, and any variation in between, including reverse reading.


Calibration is by push-button selection of menu items (detailed in the instructions)


This product has been found to NOT work with Stack fuel gauges.


As well as the traditional ways of calibrating the module, there are now pre-programmed sender profiles.


NOTE, FOR 24 VOLT USERS ONLY the Wizard requires a 12v Supply but can drive gauges that are running on a 24V supply.


This requires a 12V Voltage stabiliser to be fitted to the power line before the wizard.


add a stabiliser to your order ( below) with the stabiliser option 24V in and 12V out,
