KRAL provides a special compact module, the OMX 20, for diesel railcars with an underfloor drive. This compact module contains two KRAL Volumeters, which check fuel consumption of the diesel engine in the power pack by measuring the difference between the forward and return flow. The compact module also includes all the sensors and automatically triggered bypass lines for the forward and return flow. Already existing power packs can be retrofitted with the small compact module.

Your advantages:

• The familiar high measurement accuracy of the overall system.
• Measurement not affected by ambient conditions:
• Umgebungsbedingungen beeinflussen die Messung nicht:
   - vibration
   - high ambient temperatur
   - EMC (electromagnetic compatibility)
   - shock
• Does not need much space.
• No flow conditioning required.
• Compensation for temperature differences and reverse fuel flow.
• Up to 16 engines can be measured in one multi-motor installation.
• Consumption data and other measurement data can be collected by a data logger.
• Remote access to consumption data for central evaluation.
• System self-diagnosis.
• Linking to bus systems such as Modbus, CANbus and Profibus for communicating with control systems.
• Monitoring function for fuel system analysis.
• Displays matched to customer requirements.

If there is sufficient space, two separate KRAL volumeters are normally used.

Please note: KRAL provides fuel consumption measurement for diesel engines.
