Description
Colima Visco and Colima Viscorol magnetic level indicators have
been designed for optical viewing of liquid levels in most industrial
applications. They are also suitable for high pressure and high
temperature applications and the range is complemented by
having a pharmaceutical grade option available when requested.
The indicators can be equipped with electrical contacts or
with a potentiometer transmitter for full automation of process
management, including pressurised tanks, vats, boilers, for the
control of pumps, valves and alarm systems.
Mounting
The Colima Visco and Colima Viscorol magnetic level indicators
are installed on the side of the tank (bypass system) or vertically
on the top of the tank.
Available types
LL Side / side mounted
LF Side / base mounted
LT Side / top mounted
TF Top / base mounted
R Top insertion only
GV
Side / side mounted
Specifically designed to control methane-gas odorant
GDV
Options
Electrical bistable reed switch contacts, placed at the required
levels, thus allowing control of several operating points with a
single instrument.
When equipped with a potentiometer transmitter, they allow
continuous reading of liquid level.
