Application Considerations
• Ensure liquid is inside the temperature and pressure ranges (see specifications).
• Check that the liquid is inside recommended viscosity range 0.2 to 10,000 cP.
• Examples of products with too high of viscosity is chocolate syrup, ketchup, peanut
butter and bitumen. The switch will still detect these products but the drain time can be
very long.
• Check that the liquid density is above 37.5 lb/ft
3
(600 kg/m
3
).
• Examples of products with too low of density is acetone, pentane and hexane.
• Check for risk of build-up on the forks.
• Avoid situations where drying and coating products may create excessive build-up.
• Ensure no risk of bridging the forks.
• Examples of products that can create bridging of forks are dense paper slurries and
bitumen.
• Check if solid content in liquid
• Problems may occur if product coats and dries causing caking
• As a guideline maximum solid particle diameter in the liquid is 0.2-in. (5 mm)
• Extra consideration is needed when dealing with particles bigger than 0.2-in. (5 mm),
