Abstract
Apparatus, systems and methods for the stabilization of a mobile liquid tank during transportation of a liquid. Sensors feed information regarding the status and position of a liquid retained therein to a control unit which calculates expected movement of the liquid, and controls a set of pneumatic valves to adjust airsprings of a pneumatic suspension as to minimize undesirable movement of the liquid.
Claims20
A system for stabilizing a mobile liquid tank, the system comprising:
- at least one sensor disposed in a mobile tank;
- a control unit in communicative contact with the at least one sensor, the control unit configured to predict motion of liquid retained in the mobile tank in response to data acquired from the at least one sensor;
- at least one valve in communicative contact with the control unit;
- and
- at least one pneumatic airbag in a suspension system in operative connection to the tank, such that inflation of the at least one pneumatic airbag raises or lowers a portion of the mobile tank.

A method of stabilizing a mobile liquid tank during transport, the method comprising:
- monitoring an aspect of a liquid retained in the mobile liquid tank;
- predicting expected motion of the liquid retained in the mobile liquid tank based on the monitored aspect of the liquid;
- and
- inflating at least one pneumatic airbag to raise a portion of the mobile liquid tank to counter the predicted expected motion of the liquid.
