In the photos we see a deposit in a seat of a gyrocopter and a wing. In both you can see at a glance that a classical resistive gauge did not show us the actual capacity of the tank.
To avoid these problems, the IM-594 incorporates a microprocessor with up to 10 memories. The first time it is used, the user must connect to a PC, and through a simple menu select the tank capacity in liters and the number of steps of memory you want to use. Then the program will tell you completely fill the tank and press a button.
Then depending on the number of steps you have selected, the user must remove an amount of fuel from tank and press a button to confirm each step. In the last step, the tank must be empty.
