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.
