Apparatus and method for sensing the fluid level in a mixing device |
摘要 |
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 sensing device, such as a strain gauge, is attached to the paddle blade 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.
