Ideal material characteristics
● low cohesion (flows well through chutes, similar to a liquid)
● low adhesion (does not stick to surfaces)
● low abrasion (will not wear out chutes, flowguide, or sensing plate)
● low causticity (will not damage internal flowmeter components)
Location
Materials with low moisture content generally have excellent flow and adhesion characteristics.
In processes where material moisture content varies, select a flowmeter location where the
moisture content is lowest.
Linings
● Sensing plate abrasion resistant linings are often used for aggregates, barley, corn,
soybeans, wheat, and material with similar hardness and particle mass. Abrasive materials
are best monitored at low velocity.
