System and method for product level monitoring in a chemical dispensing system

A probe assembly for detecting a level of a product in a container, the probe assembly comprising:

• a cap coupleable to the container and having a first channel and a second channel;
• a first extension tube positioned within the first channel and having a top end and a bottom end so that the top end projects upwardly from the cap and the bottom end projects downwardly from the cap;
• a second extension tube positioned within the second channel and having a top end and a bottom end so that the top end projects upwardly from the cap and the bottom end projects downwardly from the cap;
• a first probe having a first end disposed within the bottom end of the first extension tube forming a fluid tight seal with the first extension tube, and a second end opposite the first end, the second end projecting outwardly from the bottom end of the first extension tube to contact the product;
• a second probe having a first end disposed within the bottom end of the second extension tube forming a fluid tight seal with the second extension tube, and a second end opposite the first end, the second end projecting outwardly from the bottom end of the second extension tube;
• and
• a lid separate from the cap and configured to secure the cap to the container, the lid holding the first extension tube in place against the first channel and the second extension tube in place against the second channel when coupling the cap to the container.
