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
RTop 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.
Standards and certification
Colima Visco and Colima Viscorol magnetic level indicators comply
with the following European Directives:
- PED 97 / 23 / EC - up to Class IV.

Potentiometer transmitter characteristics
A potentiometer is placed in the vertical weather-proof tube
outside the level indicator.
The total resistance of a known value is measured at the ends of
this potentiometer.
The float, following the liquid level trend, activates the potentiometer’s
reed contact chain through its own magnetic field, locally closing
the signal.
The total value of the resistance is measured 100% at its maximum
level and 0% at its minimum level.
The end poles of the potentiometer are connected to a converter
that transforms the input value into Ohm and the output into mA.
Converter types
Converter for safe area
Field set using two trimmers
[for the Z (zero) gauging and G
(gain) gauging],
without resorting to
interconnecting systems.
Converter for inbuilt safe area
Field set using two trimmers
[for the Z (zero) gauging and
G (gain) gauging], without
resorting to interconnecting
systems.
Converter HART® protocol
Converter regulated with an
interconnection cable.
