4-2.5 Utilization of Laboratory Facilities - Cont'd.
. When anew batch of fuel is received from the associated pipeline.
e.
When a major transfer is planned between different TPT's or into the associated pipeline.
f.
When jet fuel has been in storage for 30 days or more without addition of fresh stock.
g.
All fuels in storage prior to any major drawdown on which vehicles or aircraft are dependent on the quality.
h.
Routine, once per week, check of a cross section of samples analyzed with the portable testing kit to assure
proper use and accuracy of the testing kit.
4-3 Metering and Gaging
The combination of meter strainer assemblies and the range poles are used to determine the quantity of fuel movement
to and from the TPT and inventory within the TPT. Metering and gaging systems are intended for operating control and
are not intended for accounting purposes.
4-3.1 Meter-Strainer Assemblies
a.
There are 7 meter-strainer assemblies as described in para. 2-4.6 and Fig. 2-19.
Three are used to measure fuel into each fuel unit, three are used to measure fuel output at each dispensing assembly,
and one is available to install in a common header returning fuel to the associated pipeline. For location of these units,
see Fig.'s 4-1, 2-63A, 2-63B and Fig. 2-64. For further information, refer to the technical data over packed with the
equipment and Appendix A. To operate the meter for recording a fuel transfer: 1. Set the meter at zero (or alternately
record the reading) prior to the transfer.
2.
Read and record the reading at the completion of the transfer.
3.
The difference between the initial reading "1" and the final reading "2" is the amount of fuel transferred in U.S.
gallons.
b.
The strainer is installed to protect the meter. A plugged strainer will cause excessive pressure drop. The strainer
must be cleaned on a routine basis as described in Chapter 6.
c.
The meter is designed and intended for an accuracy of 0.1%. If accuracy in transfer measurement is desired, the
meter should be checked for accuracy every 2,000,000 gallons. U.S. Army publication FM 10-18, Petroleum Terminal
and Pipeline Operation, Appendix D, describes a satisfactory method of determining accuracy. The questioned meter
can also be checked against a meter of proven accuracy by installing them in series.
