Fluidimeter : AS 100

The AS 100 fluidimeter has been designed for the specific purpose of determining the spray properties of powder paints. In the electrostatic powder coating process, the powder paint is carried then sprayed on the item by suspension in air. However, paints in powder form react very differently to this suspension in air according to their grain size, degree of humidity, formula, etc.
The fluidimeter determines this behaviour and indicates immediately whether a powder paint is suitable for spraying purposes. It is a valuable aid in product quality control for both powder paint manufacturers and user laboratories.

The apparatus comprises :

A - A 100 mm diameter cylinder with a porous base in which the powder is fluidized, and with a calibrated side opening for the powder to flow through.
B - A container to collect the powder flowing through the cylinder opening.
C - A control box containing :
- Gate valve,
- Air expansion valve,
- Flowmeter,
- Pressure gauge.
