The powder may harden on the slope due to the pressure of the powder and the friction on the slope of the tank.

This state (where only the surface layer is flowing) is called "funnel flow".

If funnel flow continues, the powder may deteriorate and become clogged in the pipe.

When this sensor detects a blockage in the pipe, it stops feeding powder and sends an alarm signal.

This product also detects the upper limit of powder in the tank and sends a signal to the vibrator or knocker.

Eliminate blockages with strong vibrations from a vibrator or knocker.

The pressure of the powder may cause the upper part of the outlet to arch and stop the flow.

This is called "bridge".
The sensor detects the upper limit in the tank and sends a signal to the alarm.

The strong vibrations of a vibrator or knocker break down the bridge and clear the blockage.
