The intermediate tank monitoring system for a dual gasoline/petrol engines and two fuel tanks uses fuel rate information from the fuel flow monitor (FFM100) combined with the vessels speed from the GPS antenna/receiver (GPS200) to provide fuel economy information (e.g., miles/gallon or kilometers/liter). In addition, tank monitors provide remaining fuel information so the display can compute distance and time to empty. The TLM150 senses the level of the fluid in the tank using ultrasonic technology eliminiating the need for probes into the tank, which often foul or corrode.

The following table shows the products included within this example system plus a list of the information or data available for display.

Product	Description	Available Data List
TSM800C	Display	Displays data in this list, monitors the data and displays an alert if there is a problem.
FFM100	Fluid Flow Monitor	Monitors fuel flow rate, fuel temperature, trip fuel used.
GPS200	Cabin top GPS	Position, speed over ground, course over ground, time, date, magnetic variation and more.
TLM150	Tank Level Monitor	Monitors fuel level, fuel capacity, fuel remaining
VDR100	Vessel Data Recorder	Performance analysis, vessel tracking, preventative maintenance, warranty incident, and accident investigation
