Differences Between Innage & Outage Oil Gauging Tapes

  An oil gauging tape measure with a plumb bob is lowered down from the reference point just to the point that the bob touches the bottom of the tank or datum plate. Care should be taken to lower slowly so the bob does not reach the bottom and then tilt over.

OPEN MANUAL GAUGING. Manual open gauging involves the use of tape and bob through the open tank gauge hatch to obtain the levels of liquid in the tanks using the ullage or innage methods. This section describes the equipment and procedures to be used to perform this task.

What’s the Difference Between Innage and Outage Oil

  Innage oil gauging tapes are used with Innage plumb bobs. The zero point of an Innage gauging tape is at the bottom of the bob. The Outage Method. The Outage (or Top gauging) method will tell you the measurement of the part of the tank that is NOT filled with liquid (the level that has been taken out, or the “ullage”).

BASE SEDIMENTS AND WATER (B.S.&W.) = Non hydrocarbon solid material and water in suspension in crude oil or petroleum liquids. FREE WATER (FW) = The calculated volume of water at observed temperature and pressure , present in the ships tanks , which is not in suspension in the cargo liquid .

Ullage Wikipedia

Rocketry. On the ground, the space between the top of the propellant load and the top of the tank is known as "ullage space". In the weightless condition in space without engine thrust, empty space occurs in partially filled tanks, and the liquid floats away from the engine intake, which is undesirable for stable engine operation.

  Q1. A tank measuring 21m*15m*16m has an ullage port extending 1 m above the top of tank. It is to be loaded with crude oil at 23°C. 3% of the tank vol. is to be left for expansion when maximum temperature expected during the outage is 42°C. ( Density of oil [email protected] 15°C in vaccum). Find the mass of oil loaded and ullage at load port.

Level Measurement

Outage gauging (also referred to as ullage gauging or top gauging) measures of the tank less the gauge reading at the reference gauge point the distance from the surface of the product in the tank to a reference gauge point on the gauge hatch at the top of the tank. An outage bob is used for outage gauging.
