Title:
POWDER FLOW RATE MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2002090197
Kind Code:
A
Abstract:
To provide a powder flow rate measuring device capable of accurately setting a relational coefficient.
The device comprises a load cell 10 as powder weight measuring means for measuring a weight Q of the powder 2 passed through a first waveguide 5 and a second waveguide 6, and a relational coefficient setting means 14 for setting a relational coefficient k from a flow velocity v of the powder 2, the difference Δ of microwaves and weight Q of the powder 2. This results in allowing an accurate measuring of the weight Q of the powder 2 and an accurate setting of the relational coefficient k as compared with a conventional filling type, since the measuring of the weight Q of the powder 2 is by a dropping type.
