Sticking an oil tank is a manual method used to measure the fuel level inside the tank, typically using a calibrated stick or pole.
The process involves inserting the stick into the tank and reading the level of liquid that coats it. This method is a fundamental part of inventory control for many storage tanks, particularly underground storage tanks (USTs), as mentioned in the context of "UST Inventory Control Requirements."
The Process of Sticking an Oil Tank
Sticking a tank requires careful execution to ensure an accurate reading. Here are the general steps involved:
- Prepare the Stick: Before inserting the stick, it's common practice to apply a gauging paste (sometimes called water paste or gasoline paste) if you need to check for water at the bottom or ensure a clear fuel level reading. Mark the stick "a few inches along each side of where you think the level might be" to help anticipate the liquid line and aid in reading.
- Insert the Stick: Carefully lower the gauging stick into the tank's designated access point or 'stick pipe'.
- Lower to Bottom: "Slowly lower the stick, gently touch it to the bottom of the tank." This ensures the measurement is taken from the tank's floor upwards.
- Remove for Reading: "And then quickly remove for the reading." Removing the stick quickly helps to maintain a clear line showing the liquid level before it can drip down or spread.
- Read the Level: Observe the mark or line on the stick where the fuel has reached. If using paste, note the color change indicating the fuel level or presence of water.
- Record the Measurement: Note the measured height of the fuel in the tank. This reading is then typically compared against a tank chart to determine the volume of fuel.
This manual method provides a direct measurement of the liquid level, which is crucial for managing inventory, detecting leaks, and ensuring compliance with environmental regulations. It is often performed daily as part of routine operations.
