Container level detector

An apparatus for detecting a level of contents within a container, the apparatus comprising:

• a plug configured to mount in a hole in the container;
• a first sensor that detects a first level of the contents in the container;
• a second sensor that detects a second level of the contents in the container;
• a structural member extending from the plug to the first sensor and to the second sensor;
• at least a first internal cable extending from the first sensor to the plug;
• at least a second internal cable extending from the second sensor to the plug;
• an external cable extending outside the container;
• a wireless gateway electrically connected to the external cable opposite the signal connector;
• and
• a cloud data processing system;
• wherein:
• the second level of the contents is different than the first level of the contents;
• the structural member maintains a substantially consistent first distance between the plug and the first sensor;
• the structural member maintains a substantially consistent second distance between the plug and the second sensor;
• the second distance is different than the first distance;
• the first internal cable conducts a first level signal from the first sensor to the plug;
• the second internal cable conducts a second level signal from the second sensor to the plug;
• the plug comprises a terminal connector;
• the first internal cable is electrically connected to the terminal connector;
• the second internal cable is electrically connected to the terminal connector;
• the terminal connector is configured to releasably connect to the external cable extending outside the container;
• the external cable conducts the first level signal outside the container;
• the external cable conducts the second level signal outside the container;
• the external cable comprises a signal connector configured to electrically connect to the terminal connector;
• the wireless gateway converts at least the first level signal from the first sensor and the second level signal from the second sensor into a wireless signal;
• the wireless gateway transmits the wireless signal;
• the wireless signal from the wireless gateway includes GPS location data;
• the wireless signal from the wireless gateway is transmitted to the cloud data processing system;
• the hole is in a top surface of the container;
• the hole is threaded;
• the plug is threaded and screws into the hole;
• the plug comprises a recess above the terminal connector;
• the recess is configured to receive a tool to rotate the plug when the signal connector is disconnected from the terminal connector;
• the structural member is elongated;
• the first sensor, the second sensor, the structural member, the first internal cable, and the second internal cable all fit through the hole as an assembly connected to the plug when the apparatus is installed on the container;
• the first sensor is located vertically below the plug when the container is sitting on a level surface;
• the structural member comprises plastic tubing that is sufficiently flexible to bend adjacent to the plug due to gravity to keep the first sensor vertically below the plug when the container is sitting on a non-level surface;
• the container is a drum;
• and
• the hole is a vent hole of the drum.
