ABSTRACT:
A hydrostatic pressure equalizer device is attached to the lower submerged end of a gas supply line. A hollow housing forms an internal cavity having a closed upper end and a lower end, and an end plate extends over at least part of the lower end to leave a gap for liquid flow into the cavity. The gas supply line extends through the end plate and upwardly into the cavity to terminate at a raised position which will be in an air pocket above the liquid level in the cavity. A pressure monitoring instrument connected to the line detects pressure in the air pocket, which in turn is equal to the hydrostatic pressure in the cavity and the surrounding liquid.
