Particulate height calculations from pressure gradients

A method comprising:

• accessing, by a controller, a reference pressure level in a container;
• receiving, by the controller, a first pressure level at a first height of particulate material inside the container;
• receiving, by the controller, a second pressure level at a second height inside the container, the first pressure level and the second pressure level being measured as gas is supplied into the particulate material;
• determining, by the controller, a linear pressure gradient that extends through the first pressure level and the second pressure level;
• and
• calculating, by the controller, a height of the particulate material in the container from the determined pressure gradient and the reference pressure level.

A system comprising:

• a bin having a bed and a fluidizer plate on which particulate material is supported, wherein the particulate material is to be conditioned by a gas supplied through the fluidizer plate;
• a first pressure sensor to measure a first pressure level at a first height within the particulate material as the particulate material is conditioned;
• a second pressure sensor to measure a second pressure level at a second height as the particulate material is conditioned;
• a controller to,
• determine a linear pressure gradient from the first pressure level and the second pressure level;
• and
• calculate a height of the particulate material in the bin from the determined linear pressure gradient.
