Because values less than the first and greater than or equal to the last row are considered invalid and are ignored, it is recommended to add an input value higher than the maximum possible in the last row of the table. For example, 1024 or 4096 for sensors that transmit the maximum fuel level in the ranges of 0-1023 or 0-4095. The output value can be calculated linearly.

For UMK-3xx terminals, the STATUS field is displayed in decimal form at the input *А(100), GNSS signal suppression changes the ninth bit. In the sensor, set the expression getbit(adc100,9)

The aggregating function "Sum" is used **when one fuel level sensor is installed in each tank** .

63

64

The aggregating function "Average" is used **when several fuel level sensors are installed in one tank** .

**Fuel level ** with ignition validation

67

68

When using standard fuel sensors with an inverted calibration table, an effect occurs when the voltage from the sensor drops to 0 when the ignition is turned off, which is detected as a full tank. For filtering, you can use validation by the ignition sensor.

71

To do this, we create physical sensors for ignition and fuel level, indicating the aliases ign and fuel

77

Then we create a virtual fuel level sensor with the expression **//if(ign, fuel, 0)//** - if the ignition is on, then we transfer the fuel as it is, otherwise we transfer 0 instead. Fill in the calibration table with 2 lines - 0 - 0 and maximum_tank_volume - maximum_tank_volume, which will cut off the 0 obtained from the formula condition. As a result, the system will consider invalid the fuel level obtained with the ignition sensor turned off.

**Fuel level ** on the sensor with the changed input number.

84

85

To do this, we create physical sensors with the Arbitrary type, calibration tables, old and new input numbers, and specifying fuel_old and fuel_new aliases.

88

Then we create a virtual fuel level sensor with the expression **//if(time > cdate('2021-12-22 00:00:00', 'yyyy-MM-dd HH:mm:ss'), fuel_new, fuel_old) -//** after 2021-12 -22 00:00:00 (UTC time) fuel is displayed from the new FLS, and up to this time inclusive from the old FLS.
