Abstract
A bi-level tank includes a transfer tank with a transfer port configured to open and close and a return tank with an upper displacement line port and extending upright from the transfer tank to and beyond the upper displacement line port, the transfer port between the transfer and return tanks. A displacement device is mounted for displacement in a displacement tank having a lower displacement line port. A displacement line coupled between the upper displacement line port above the transfer port and the lower displacement line port below the transfer port fluidly connects the return tank to the displacement tank. A balance line below the transfer port fluidly connects the transfer tank to the displacement tank. The displacement device is operatively coupled to the lower displacement line port to effectuate fluid transfer between the displacement tank and the return tank via the displacement line when the displacement device actuates.
