TM 10-3835-231-13
j.
Metering and Gauging. The meter skid assemblies are used to determine the quantity of fuel movement to and
from the TPT. The range poles are used to determine the approximate inventory in the tanks and physically indicate a full
tank. Metering and gauging systems are intended for operating control and are not intended for accounting purposes.
(1)
Meter Skid Assemblies.
CAUTION
PURGING AIR THROUGH METER SKID ASSEMBLY
The positive displacement meter cannot be subjected to any substantial airflow without
running the risk of overspeeding and ruining the meter. Fill rates should be kept under 50
gpm until the meter is flooded.
(a)
There are four meter skid assemblies in the TPT system. Three are used to measure fuel into each
fuel unit, and one is available to install in a common header returning fuel to the associated pipeline or user facility. To
operate the meter for recording a fuel transfer:
1 Set the meter at zero or record the initial reading prior to the transfer. Do not reset the meter
register while the meter is operating.
2 Instantaneous flow rates are read on the flow rate indicator during fuel transfer.
3 Read and record the reading at the completion of the transfer. The difference between the initial
reading and the final reading 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 regularly.
(2)
Range Poles.
(a)
Range poles are installed at each 5000 bbl fabric collapsible tank to help prevent overfilling. If the
range poles are installed as suggested in this manual, the following procedures apply.
1 The height of a 5,000 bbl tank is specified to be approximately 6 ft. 8 in. when it contains 5,000
bbl. The tank top should be touching the cord between the two range poles.
2 If the tank top is approximately 3 ft. 4 in. below the cord, the tank contains approximately 2,500
bbl.
(b)
The position of and the tightness of the cord between the range poles should be checked routinely to
assure that it is located 6 ft. 8 in. above the tank bottom (or some other fixed height specified by operating management).
A small block of wood or a split ball at the center of the cord will help steady it and provide a good reference point.
