OPERATING PRINCIPLE
This component interfaces two pressure media in a high pressure chamber. Using two media of different densities allows a natural separation between the two fluids that can be referenced to an indicating pointer in the VLI and viewed through a transparent lens.

INITIAL SETUP
Place the VLI on the same surface as the piston gauge or other reference to which it is to be connected. Ensure the VLI and the connecting hardware are clean and free of contamination. Connect the VLI to the standard using the connecting hardware supplied. If the piston gauge medium has the greater density, the connection should be made at the lower port of the VLI. If this is not true, then the connection should be made at the middle port. Fill the VLI through the connecting hardware to the tip of the interface level indicator with the fluid that has the highest density. Carefully fill the rest of the VLI with the lighter medium until the air is completely displaced form the VLI. When interfacing a gas medium with a liquid medium the control of pressure must be performed on the gas side. A variable volume in the hydraulic side is necessary to adjust the change in the interface level as pressures and temperatures change.

OPERATION
2. 3. 1 INTERFACING TWO LIQUIDS (OIL, WATER, ETC. )
Pressures can be generated from either side, or on both sides. The interface reference level can then be changed by adjusting the volume on either side. [. . . ] This condition could lead to outgassing (rapid boiling) when returning to zero. To prevent boiling liquid into the gas or gas into the liquid, decrease pressures slowly to approximately 200 psi (1. 4 MPa). Hold that pressure until outgassing has apparently stopped and then decrease to zero.
