ELBOW-UNION 2P2204 - Caterpillar

All Caterpillar Truck EnginesThe Caterpillar fuel flow monitor system is now available. See Illustration 1. This system is a versatile fuel flow measurement system to help evaluate engine performance. The system is powered by 11 to 40 volts DC at 1.2 amps from the engine battery or other source.
Illustration 1. Major components in the Caterpillar Fuel Flow Monitor System.The monitor system can be used as a two-meter system on engines with both supply and return-to-tank fuel lines, or as a single-meter system for engines without the return line. It uses two fuel flowmeters and a hand-held monitor to measure fuel flow and fuel temperature of both supply and return lines, and to calculate the burn rate of the engine. The held monitor also will display average and total fuel burned during a given period of time. The monitor instantly indicates out-of-range conditions such as underflow or overflow. The information can be displayed in S.I. (metric) or U.S. units.
The state-of-the-art "smart" turbine flowmeters contain microprocessors which linearize the output signals of both flow and temperature to give a meter reading accuracy of 0.5%. They also automatically compensate for the expansion of fuel as it changes temperature. The meter groups are all fully field-tested to ensure accuracy. Pulse dampeners, flow straighteners and sight glasses are included.
The 1U5430 Fuel Flow Monitor Arrangement For All Caterpillar Truck Engines
This arrangement has all the parts needed for all Caterpillar Truck Engines. The range of both flowmeters is 11 L/hr (3 gph) to 265 L/hr (70 gph). See Illustration 2 and the chart for these parts.
Illustration 2. The test arrangement for Caterpillar Truck Engines.The Operating Manual NEHS0502-01 is provided with the arrangement. It contains specifications, in structions and a list of service parts. This manual covers many other parts and lists information not applicable to truck engine applications. Larger flowmeters are available for larger engines with fuel flow rates from 150 L/hr (40 gph) up to 3785 L/hr (1000 gph).
