SCREW-FLAT HEAD 1195025 - Caterpillar

1U5450, 1U5440 and 1U5430 ArrangementsIntroduction
The Caterpillar Fuel Flow Monitor System is a versatile fuel flow measurement system, designed to help evaluate engine performance. This fuel flow monitor system uses two fuel flowmeters and a hand held monitor to:* Measure fuel flow and fuel temperature of both supply and return-to-tank fuel lines.* Calculate the fuel burn rate of the engine.The Caterpillar Fuel Flow Monitor System can also be used as a single flowmeter measurement system on engines that do not have a fuel return line.Information on the average and total fuel burned by the engine over a period of time is also provided by the hand held monitor.State of the art turbine flowmeters are used with this system to measure fuel flow. These turbine flowmeters each contain a microprocessor that linearizes the output signals, and temperature corrects the flow rates to provide accurate fuel flow and fuel temperature data.The output of the flowmeters is a digital signal that communicates directly with the fuel flow monitor.The Fuel Flow Monitor System (FMS) is available in two sizes, to measure fuel flow on most Caterpillar engines.The flowmeters connect directly to the hand held monitor. This monitor displays fuel flow and fuel temperature information.In addition, the burn rate of the engine is displayed. Internal memories record the average fuel burn rate over a period of time and the total fuel burned. This information can be displayed in either Metric or English units.Fuel Flowmeter Rework Program and Part Number Changes
Some of the componets in the Fuel Flowmeter Group have been reworked, at the factory, to improve reliability.The reworked componets, in factory stock, have the new (replacement) part numbers.The three main arrangements part numbers 1U5430, 1U5440 and 1U5450 have NOT been changed and can still be ordered.The reworked componets can also be identified by the letter A stamped after the part number.In the following list the left column is the original part number and the right column is the new (replacement) part number.The part description remains the same. 1U5301 Supply Flowmeter Group (small) ... 4C97581U5302 Supply Flowmeter Group (small) ... 4C97591U5303 Supply Flowmeter Group (large) ... 4C97601U5304 Supply Flowmeter Group (large) ... 4C97618T9119 Flowmeter (small) ... 4C97628T9121 Flowmeter (large) ... 4C97631U5300 Monitor Group ... 4C97648T9177 Sight Glass (small) ... 1U92118T9176 Sight Glass (large) ... 1U9212Components of the Fuel Flow Monitor System
