Note: The level sensor in the dispersion unit stops the tank being overfilled
above a certain level. This level, when the dispersant is detected and the tank
light flashes, depends upon the liquid that has been used in the tank. A
threshold value needs to be applied to the level sensor for all liquids other than
water. If the tank fails to fill properly, this threshold for the dispersant being
used, may need to be adjusted. Control of a dispersion unit via an SOP on
page70 and Accessory controls panel on page71
Manual fill advice
Fill the tank slowly, until the light flashes — this indicates the correct level for sample addi-
tion and running measurements. If the tank is filled higher than this, sample and particles
could drain into the over-flow system (drain). This will lead to an incorrect particle size dis-
tribution being reported.
The tank fill indicator in the software also indicates the fill level. Refer to Accessory control
settings — Hydro LV/MV in the Masteriszer 3000 user manual.
Tank cover
The tank cover protects the tank from splashes. Always replace the cover after sample is
added to the tank.
To remove and replace the tank cover, hold on to the raised portions of the cover.
