Abstract
Apparatus and method for determining: proper operation of a cleaning system, the depth of liquid in a drum, the predicted failure of a pump, improving the ability to monitor cleaning system, improving the ability to monitor dairy wash systems, improving the ability to monitor animal husbandry systems, and/or increasing the efficiency with which various types of equipment, fluid levels, and/or systems can be serviced or monitored.
Claims20
A sensor apparatus for measuring a depth of a liquid in a drum, the sensor apparatus comprising:
- a tube having a first end and a second end, the second end being configured for placement within the liquid, the tube having a first internal diameter proximate the first end and a second internal diameter proximate the second end, wherein the first internal diameter is less than the second internal diameter;
- a seal positioned in the tube;
- a first sensor disposed in the tube proximate the seal and configured to measure air pressure in the tube;
- a processor in electronic communication with the first sensor, wherein the processor is configured to automatically determine a volume of the liquid in the drum.

A sensor apparatus for measuring a depth of a liquid in a drum, the sensor apparatus comprising:
- a tube having a first end and a second end, the second end being configured for placement within the liquid, the tube having a first tube section proximate the first end and a second tube section proximate the second end, the first tube section having a first internal diameter and the second tube section having a second internal diameter, wherein the first internal diameter is less than the second internal diameter;
- a seal positioned in the tube and spaced from the second end;
- and
- a first sensor disposed in the tube between the seal and the second end and configured to measure air pressure in the tube.
