Megawatt-Hour Meter and

Fuel Level Monitoring

TMV’s Megawatt-Hour Meter calculates total power output and displays data on an LCD color touch screen, along with useful statistics and optional Fuel level Monitoring.


– Easy to install and operate 
– Displays instantaneous Kilowatts
– Displays trip Megawatt-hours 
– Displays total accumulated Megawatt-hours
– Ability to track megawatt hours between scheduled

   preventative maintenance intervals
– Fuel Level Monitoring

O Medidor Megawatt-Hora é um conjunto equipado por um painel de tensão e um sensor de corrente. 

O painel exibe a tensão do Gerador Principal e o sensor mede sua corrente, esses dados são utilizados para calcular a potência total de saída.

The above diagram shows how the Megawatt Meter ties into the locomotive’s systems. 

The Current Sensor is placed on one of the cables connecting the Main Generator to one of the Buses.
The current measured will be multiplied by total number of cables between the Main Generator and the Bus to determine total current output of the Main Generator. 

The High Voltage Panel has two leads connected to each Bus of the Main Generator to determine total voltage output.

The Display Unit uses these two figures to calculate the total power output from the Main Generator.

Fuel Level Monitoring Alone:


If fuel level monitoring is all you’re looking for, without megawatt hour tracking, your display will come with an ultrasonic fuel level sensor, and two fuel displays for each side of your locomotive. 

Fuel Level and Megawatt Hour Monitoring:

To get an accurate picture of your locomotive’s energy expenditure (and to find out whether your energy-saving efforts are working), pair the Megawatt Hour feature with the Fuel Level monitoring feature. These together will gather for you the most accurate data. This data is stored as trip logs and collectively.
