Challenge: Finding an NSF Certified, non-moving-parts, low-cost liquid level sensor
Since this machine is used in public restaurants, the components within the machine must be NSF (National Sanitation Foundation) certified, and safe for food and water use. An NSF certified device is allowed to come in contact with food so that it will not cause any contamination or buildup.
The ELS-950N is an NSF 169 certified, direct contact level sensor that lets the machine know when the liquid sweetener is running low and needs to be refilled. Without this type of NSF certified sensor, the machine could run dry, as well as be unsanitary.
