Fluid level in a container is determined using a single pressure transducer connected to a portable body. The body contains a computer having a memory in which fluid level-to-fluid volume conversion data are stored for different shapes of containers so that fluid volume can be readily obtained for the shape of the respective container once fluid level is determined. These features allow a single monitoring apparatus to be used for monitoring different types of containers. The apparatus preferably includes a radio so that multiple apparatus can communicat...
A method of monitoring fluid in a container, comprising: (a) sensing with a totally submersible pressure sensor the pressure of the fluid at a first depth of the fluid; (b) sensing with the pressure sensor the pressure of the fluid at a second depth of the fluid, the second depth a known distance from the first depth; (c) sensing with the pressure sensor the pressure of the fluid at the bottom of the fluid; (d) determining the density of the fluid in response to the pressures sensed in said steps (a) and (b); and (e) determining the height of the surface...
