Fuel prices have increased dramatically.
Control vthicle fuel consumption and save your money.

Fuel Monitoring without Extra Fuel Level Sensor.

No need to install fuel level sensor.
No need to drill fuel tank.
For fuel monitoring you can use regular vehicle fuel level sensor (analog or Pulse-Analog).

Ideal for the situation when is not possible to install extra fuel level sensor:
- physical is not any place for extra fuel sensor installation;
- forbiten or vehicle owner dont want to drill hole in fuel tank;
- very hard to mount extra fuel sensor (need to remove fuel tank. As usual in LCV);
- vehicle with petrol engine (very hard and riskily to drill hole in petrol tank).

GuardMagic DAFS3 allows by very economical way embed fuel monitoring function for cars, VANs, SUV, LCV in vehicle monitoring system.
(also in trucks and other vehicle and special machinery).

GuardMagic DAFS3 is intended for connection vehicle (car, LCV, Truck etc.) regular floating fuel level sensor to GPS-GSM/GPRS module.

GuardMagic DAFS3 read the analog signal from the vehicle regular resistive type floating fuel level sensor, valuate, processing input signal and converts it into:
- digital form: RS-232 communication interface;
- stable noise and pulse free analog voltage output 0... 9 V (10V) range. (Customer setting)

Advantages:
- 12V / 24V vehicle power;
- Dual input: "Analog" "and Pulse-Analog";
- Wide voltage input range;
- Valuation of the input signal;
- Input signal processing;
- Internal programming filter;
- Programming the operating parameters;
- Dual output: analog and RS-232;
- High resolution.

Why DAFS (or why and when to use DAFS):
- Is not possible to install extra fuel level sensor (is not any place for extra fuel sensor)
- Cars, LCVs, buses with petrol engine. Very hard to work with petrol fuel tank.
(Will be need to remove fuel tank from vehicle and make degassing of it).
- Forbitten to drill fuel tank or vehicle owner dot want to drill vehicle fuel tank

others:
- Any standard vehicle tracker dont work correctly with vehicle regular fuel level sensor.
( Output voltage value of regular vehicle fuel sensor depend of power voltage fluctuation: engine RPM etc )
