Engine Commercial All DieselIntroduction
This Special Instruction contains information for installing and configuring the Fuel Consumption Monitoring System on all Caterpillar and non-Caterpillar diesel engines. The Fuel Consumption Monitoring System will measure the net volume of fuel used by an engine. There are three available arrangements:
single transducer up to 30 L/min (7.9 US gpm)
dual transducer up to 30 L/min (7.9 US gpm)
dual transducer up to 100 L/min (26.4 US gpm)The Fuel Consumption Monitoring System can accommodate engines with supply and return fuel lines, or a supply line only. The Fuel Consumption Monitoring System will transmit the collected data to the main data link to be received by a recording and reporting ECM, such as Cat® Product Link. This data will then be sent to the back office. Refer to Section "Fuel Transducer Accuracy" for information on system accuracy.Note: For the single transducer system, disregard any instructions regarding a return transducer. Additional information will be noted as necessary in the following sections of this document.Important Safety Information
