The EFMS100 Engine and Fuel Monitor System is based on TX100 sender unit and RX100 display unit.

  • The sender unit is typically installed near the engine
  • The display unit is typically facing the user


EFMS100 System highlights

  • All sensors are connected to the sender unit. Only 1 small cable connects to the display unit
  • Very low power requirements: Operates from the vehicle battery (e.g. 12V battery) or 1 small 9V battery
  • No additional battery required to save user configuration: all configurations and data are saved in FLASH memory



RX100 display unit highlights

  • Large, anti-glare, anti-scratch, high contrast, 128x64 pixels LCD display
  • Fully customizable parameter screen (parameter names, locations and character size)
  • Easy to use: menu driven interface with navigation button on the side


TX100 sender unit highlights

  • High quality terminal block connections ("rising cage design") allow you to use probes (EGTs, CHTs, etc...) from any vendor

Engine tachometer and hour meter

  • Supports all types of 2-stroke and 4-stroke engines
  • Sensor cable (provided) simply wraps around engine ignition wire


  • 4 thermocouple inputs (EGT, CHT, water, oil, etc...)
  • Ambient temperature sensor built into the sender unit

Battery voltage: Monitors the vehicle battery voltage (or the voltage of the 9V supply battery).

Fuel information based on optional fuel flow sensor

  • Fuel flow
  • Fuel used
  • Fuel onboard
  • Time to tank empty
  • Distance to tank empty (after entering your speed)


Auxiliary inputs

  • 2 general purpose inputs
  • Examples of applications:
    • Fuel level sensor or detector
    • NTC thermistor (temperature sensor)
    • Additional voltmeter
    • Etc.


  • Various purposes (i.e. flight time, engine run time, etc...)
  • Multiple options for activating the timer


  • Alarms can be set on any parameter
  • Ultra bright red flashing LED on display unit alerts the user of an alarm condition. In addition, the parameter is immediately highlighted on the screen


Statistics Records minimum, maximum and average values of any parameter
