Title:
APPARATUS FOR SENSING THE FLUID LEVEL IN AN INK AND WATER MIXING DEVICE
Document Type and Number:
WIPO Patent Application WO2001042014
Kind Code:
A3
Abstract:
A sensor for detecting the level of circulating fluid in a tank comprises a paddle blade disposed at a particular height and oriented generally radially from a rotating shaft in the tank. A sensiing device, such as a strain gauge, is attached to the paddle blade (30) to detect when the paddle blade is in at least one of a normal and a displaced position, thereby indicating that fluid is absent or present at a particular level. Additional sensors may be used in the same tank to provide fluid level feedback at more than one height.
