Soldiers storing or transferring class III products must accurately account for receipt, issue, and stocks on hand for both bulk and packaged products. The biggest challenge in accounting for Class III products particularly bulk products is adequately measuring them. This section discusses petroleum accounting records and reports. It also discusses petroleum measurement techniques. DA Pamphlet or as appropriate give detailed procedures for bulk petroleum accounting procedures.
A discussion of accountability forms follows. DA Form Property Record. The opening inventory is the total amount of bulk petroleum on hand at the beginning of the month. Record physical inventories on DA Form use the 1-67-1 block for petroleum tank vehicles.
Estimate the closing inventory for collapsible tanks by subtracting issue totals from receipt totals. Calculate the monthly loss by subtracting the closing inventory from the closing book balance. Determine the maximum allowable loss by adding the opening inventory to the receipts. Then multiply this figure by. Special equipment is needed to measure bulk petroleum.
Innage and outage, are the two basic ways of measuring bulk petroleum. Innage is the depth of the product from its surface to the tank bottom or datum plate. Outage also called ullage is the height of space above the liquid from a reference point on the tank to the surface of the product.
This equipment is given below. The two types of tape and bob are innage and outage. They are used to measure petroleum in fixed storage tanks. Figure, shows an innage tape and bob. The tip of the bob is the zero point of the tape and bob.
Figurepageshows an outage tape and bob. The zero point is the point of contact between the snap and the eye of the bob. A petroleum gage stick is used to determine the innage of a tank vehicle or a nonpressurized tank car. The bottom of the stick usually has a hard metal tip. The gage stick should be long enough to gage the entire height of a tank.
When using the stick, make sure to lower it vertically into the tank as shown in Figurepagestep A. Make sure it does not rest on a rivet head or other object within the tank. When lowering the stick, be do not splash the product and cause an inaccurate cut. Each tank vehicle has its own gage stick which is graduated in gallon divisions. The only difference in use between this stick and the petroleum gage stick is that the product cut is recorded in gallons.
Estimate as closely as possible the indicated volume when the cut mark falls between divisions.
Concepts and Equipment of Petroleum Operations (FM 10-67-1)
The 5,gallon tank semitrailers have gage sticks marked at the top to show which scale to use for each tank compartment. A yardstick, along with the graph shown in Figurepagestep B, can be used as a field expedient to determine the approximate number of gallons in a gallon drum. To do this, place the drum in a vertical position. Lower the yardstick into the drum to get a wet-inch-depth reading.
Use the tank car gage stick to determine dome innage and shell outage in nonpressurized rail tank cars that have shell outages of 1 foot or less. If the tank car has more than 1 foot of shell outage, use a petroleum gage stick or an innage tape and bob.
The tank car gage stick is made of hardwood or similar material. It is 36 inches long. A brass angle is used to position the gage stick.
The angle is attached at the zero mark on the gage stick. Use the gage stick as given below. Using the tank car gage stick to determine dome innage and shell outage. The portable petroleum sampling and gaging kit Figurepage is used at bulk storage facilities. It is used to gage tanks and to measure product temperature. Also, it is used to detect bottom f, and water, to make volume calculations, and to sample fuels.
It weighs 22 pounds. 10-667-1 kit consists of an aluminum carrying case fitted with measuring and sampling equipment. The major parts of the kit are listed below. Gaging operations requires using special f.
Definitions of the following terms are found in the glossary. General safety gaging procedures are given below. Gage tankers and rail tank cars with specific measuring devices as described in the paragraph above. To measure bottom f, and water, do the following:. Use innage and outage tape bobs to measure petroleum tanks. They are usually used for large, fixed storage tanks. Procedures for their use follows. Review the last innage gage sheet posted to determine expected product level before gaging a tank.
To get an innage gage using the innage tape and bob, refer to Figurepageand follow the steps below: Place the unmarked side of the tape against the metal rim of the gaging hatch reference point. To determine this, compare the length of the unwound tape with the reference height of the tank.
Make sure the bob does not rest on a rivet or other obstruction. Make sure the tape is not lowered so far into the tank that the bob tilts and causes an incorrect gage. To ensure accurate gage, compare the tape reading at the reference point with the reference height of the tank. Record the cut as the innage gage. If the cut is hard to read, put product-indicating paste on the tape.
Grease or light lubricating oil may be used instead of the paste.
Gage the tank again. It is usually easier to see the product cut on the back of the tape. When taking opening and closing gages, use the same gaging equipment and hatches for both gages. Make sure the tape is lowered to the same depth for both gages.
Lower the tape slowly until the bottom of the bob is 2 to 3 inches below the surface of the product. Record the reading on the tape at the reference point as the tape reading.
It is the cut is hard to read, put product-indicating paste on the bob and gage the tank again. Outage tape and bob use. To get an outage gage or ullage using an outage tape and bob, refer to Figurepageand follow the steps below. If the product cut is hard to read, put product-indicating paste on the bob and gage the tank again. Bottom sediment and water. Measure for bottom sediment and water each time storage tanks containing liquid petroleum products are gaged. This is necessary to find the actual product amount present in the tank.
Bottom sediment ffm water often accumulate in different parts of a tank bottom. They usually accumulate on the side opposite a filling line or on either side of an outlet. When the tank has several hatches, take gages from each hatch. Average the gages to get one bottom sediment and water gage for the entire tank. Measure the height of bottom sediment and water by doing the following: Put a vm, even coat of paste on the part of the bob that will be at the point where water and product meet.
Be careful not to put so much paste on the bob that it will cause a false reading. If the depth of the water is greater than 01-67-1 length of the innage bob, use a water gage bar Figure to measure the water in the tank. Determine this by comparing the length of the tm tape with the reference height of the tank. Make sure the tape is not lowered so far into the tank that the bob will tilt and cause an incorrect reading.
Keep it in position for 15 to 30 seconds for heavier products. There should be no paste left on the portion of the bob that was in the water or the paste should be discolored.
Record the water cut as a water innage or outage. During gaging operations, take product temperature. When gaging large amounts of product, take several temperature readings at various depths. An average of these readings gives the true product temperature.
Cm gives the minimum number of temperature readings and the measurement levels for various product depths.
