Español     Fuel Level Gauges 52mm Diameter Max. 15 Galons The IM-594 can be connected to most of the resistive gauges.   Unlike other indicators reading is in liters and gallons instead of a percentage.   Many times, the float senders are linear, but the shape of the deposit is not rectangular. This is a big problem especially in tanks installed in the wings and that instead of being rectangular, having the shape of the wing.   The instruments use a pointer thats turns 240º, witch gives them great resolution.   This instrument needs a power supply of 12V or 24V.   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.
