Database by clicking Add to database.
level sensor
threshold 
(Hydro MV only)
A value can be inputted that is suitable for the level sensor to
detect the dispersant level when filled. The value will be dif-
ferent depending upon the dispersant used.
The level sensor in the dispersion unit automatically stops
the tank being overfilled above a certain level. If the tank fails
to fill properly then the level sensor threshold, for the disper-
sant being used, may need adjusting. This value can be
changed either manually (for the current measurement only)
or by using the dispersants database, to store the new val-
ues for future use.
Configuring this threshold value will be done using the
accessory controls window; this is described in the Hydro
series wet dispersion units guide.
