TTE provides an estimate of the number of hours and minutes remaining before the fuel tank is
Empty and is based upon Average Gallons/Hour gauge. UltraGauge uses either the vehicle’s
Fuel Level Sensor, if present, or it calculates the remaining fuel by continuously tracking the
amount of fuel used. See the Fuel Sender Section for more details.
Zeroing the Average Gallons/Hour gauge restarts TTE. Average G/H is zeroed by selecting:
With Fuel Tank Sensor:
When a sensor is present, UltraGauge can determine when the tank is refilled and TTE/DTE
will be updated automatically. The Time to empty is determined by the average fuel use and
the number of gallons in the fuel tank. When a fuel level sensor is present, the TTE Gauge
Range is 0 to 999 hours and 59 minutes.
Without Fuel Tank Sensor:
When a fuel level sensor is not available, or the Fuel Sender Mode is set to
Disabled
,
UltraGauge has no ability to sense the actual fuel level. It is necessary that UltraGauge be
informed each time the tank is filled. To do this, select
from the Gauge
screen
.
UltraGauge then assumes that the tank has been filled and contains the number of
from the Gauge screen.
Selecting fuel fill-up affects gauges
DTE, TTE
and
Fuel Level
. No other gauges are
affected
NOTE:
When a fuel level sensor setting is set to
Disabled
or
Smart
, Time to Empty can
become negative and the range is -99.59 to 999.59 hours:mins. A negative number
indicates the elapsed time since the estimated remaining fuel reached zero gallons.
There is always an amount of fuel in the tank and in the system that the vehicle’s fuel
level sensor cannot detect. Hence it is likely that the vehicle can travel several miles
beyond the point that TTE becomes zero.
NOTE:
Do not rely on this gauge until you have become comfortable with the accuracy of
UltraGauge.
NOTE:
The alarm for this gauge is set in hours and fractions of hours, not Hours and minutes.
A setting of 0.5 is 30 minutes
