Flowmeter in-feed chutes

The flowmeter in-feed chute delivers the material from the bin or feeder discharge to the

flowmeter flowguide. The ideal in-feed chute pre-conditions the material flow to minimize

the effect of abrasion, velocity variation, feeder discharge trajectory variation, and pulsing.

• commonly used for grain applications

• feeder discharge damping required when slow elevators

(typically chain drive) produce heavily pulsing material

discharge

• use deadbox if required to reduce material velocity from fast

elevators (typically re-inforced belt drive)

• produces a non-pulsing material discharge

• reverse flowguide transition (and/or material discharge baffle)

often required for variable belt speeds or constant speeds in

excess of 1 m/s (200 feet/minute)

• operates at a constant (and relatively low) velocity

• reverse flowguide transition not normally required but use

feeder discharge damping or a discharge baffle to minimize the

pulsing material discharge

• produces a non-pulsing material discharge

• use reverse flowguide transition for variable speed varieties
