Fuel Gauge Interface Module Ohm Range Converter for Any Fuel Gauges to Match Specific Ohm Range

Fuel Gauge Interface Module Ohm Range Converter for Any Fuel Gauges to Match Specific Ohm Range

Note:FM102：input signal from fuel sensor：Voltage，output signal to fuel gauge：Ohm Resistance

Fuel Gauges are designed to work with a specific ohm range. Different automobile and gauge
manufacturers use different ohm ranges to correctly operate their gauges. This can cause
problems for a person who is updating their vehicle with new gauges or a new gas tank and
fuel sender.
This module will allow you to use your stock sender with any fuel gauge and vice versa.

Features

1. Acts as Interface Between Fuel Senders & Gauges
2. Reads any fuel sender
3. Works with any fuel gauge
4. Accurately Corrects OHM Mismatch & Erratic Movement from Fuel Slosh
5. Custom Calibration for empty, half level and full
6. Mini Size 20(w) x 16(H) x35(L) mm

Instructions

1. Instructions
1/Mount module in a clean dry cool position.
2/Connect wires as guide photo above
3/Using store mode,program and store Full,Half,Empty and “Power on” positions.
4/Using power on mode,program how you want the gauge to operate when car is started.
5/Operated in run mode and check.

IMPORTANT NOTICE
When adjusting the screw, move gauge from Full to Empty to avoid hysteresis error.
Some gauges are very slow to move. Please allow time to stabilize.
The tank sender must have the same Ground as FM102 , otherwise erratic readings will result.

FM102 will convert input voltage signal to a target resistance signal,It can directly connect to our ultrasonic oil sense and send the oil level information to the oil level gauge
The Full,Half,and Empty position can be programmed.
The“in-between” positions between F,1/2,and E are calculated by the microprocessor and are linear.
The“power on” gauge start position is selected from either the sender position or the programed position.
The output is a npn pulse width modulated signal which may cause“buzzing”in undamped gauges.
