The HERMetic DIP Type 2 dipstick is designed for checking that the bottom of closed and inerted tanks is dry and free of deposits after crude oil washing. It consists of a graduated brass/stainless steel weight attached to a graduated stainless steel tape wound up on reel and an adapter for connecting a HERMetic valve. The operation is carried out with reduced escape of gas from the tank to the atmosphere.

This device is a portable product. It must not be permanently installed on the tank and must be disconnected after use and stored in a safe and dry area.
Operation
1、Install the HERMetic DIP2 on the HERMetic valve via the quick coupling device.
2、Open the valve.
3、Lower the dipping rod into the tank down to reaching the bottom. Looking to the tape graduation and feeling
the weight dropping off the hand line will allow the operator to evaluate when the level indicating rod is
reaching the tank bottom.
4、Once the rod is touching the bottom of the tank, the presence of deposits can be determined by giving out
slightly more tape.
5、If the dip remains in the vertical position, that means it has penetrated deposits.
6、If it tilts on the side, no deposits are present, providing they are not too hard for the dip to penetrate in or not
too soft for the dip to remain standing up.
7、After this check rewind the dipping rod into its storage tube.
8、Close the valve.
9、Disconnect the DIP2.
10、Clean the DIP 2 before the next check..
Maintenance
For long service life, maintain the HERMetic DIP 2 clean and well lubricated and, when not in use, store it in a dry and protected location.
The spring loaded coupling and mating Valve quick-connect nipple must be kept free of corrosion.
If grease is used for this purpose, it must be one which contains graphite.
When ordering spare parts, always state the drawing and the item number.
