Long - Seller item and Rich variations
Paddle type level switch is density measured by detection contact type level switch. 
Also, don't just replace the detection paddle to the measurement of very low density of the sensitivity adjustment trouble, fewer worries, even if the changes measured in the same tank to malfunction. 
Then switch the level most suitable for level detection of particulate solids level switch because through a simple mechanical principles and a method other than to shock and vibration, no problem adhering to detect paddles and spindle can be said.
