Mini-Squing prevents ink spills
BENEFITS
n Minimum intrusion into the tank
n Unaffected by agitation in tank
n Integral LED local alarm indication
APPLICATION
Different printing inks in vertical steel cylinders manufactured by an
OEM for the printing industry.
Three ink tanks are combined on a skid which is integrated into the
printers production line.
CHALLENGES
Many processes have batching and header tanks, and there is usually
the need to control a pump to maintain levels between set points,
keeping the process supply line going. The products in the tanks are
inks and dyes and the filling level in the tanks must be monitored to
prevent overflow and costly waste of product.
There are stirrer blades in the tank, therefore minimum intrusion of the
level instrument is required.
SOLUTION
The Mini-Squing from Mobrey Measurement offers short fork
technology allowing minimum intrusion into the tank.
The Mini-Squings are mounted via taper threaded connection into
stainless steel vessels.
Some of the tanks have agitation ‘stirrers’; this does not effect the
MiniSquing, as splashes on the forks do not cause spurious alarms. For
a switch in the MiniSquing output to occur, in this case the high level
alarm, the fork must be partially immersed in the product. Each unit
is factory calibrated to switch at 13mm (½”) up the fork (horizontally
or vertically mounted) in water. If the liquid is more dense, the
switchpoint will be slightly lower then 13mm (½”) and if the liquid is
less dense the switchpoint will be slightly higher than 13mm (½”).

LEVEL PRODUCTS MINI SQUING
The MiniSquing switching time is set to 1s wet to dry/dry to wet. This
means that the unit must be immersed in the liquid for one second
before the output will change.
