GTM - GRAPHICAL TANK MONITOR

GENERAL OVERVIEW

The GTM - Graphical Tank Monitor is a ready to use system for tank
monitoring, complete with level and temperature indication. Also included are
two level alarms per tank, allowing the GTM to prevent overflow, or to actuate
other devices at predetermined levels.
The GTM accepts any two-wire, level sensor with a 4-20 mA output. Linear
(vertical) tanks require only two point scaling, which can be performed either by
keying in the current signal, or through the use of its built in learn mode. For
nonlinear applications, such as horizontal tank measurement, up to 100 scaling
points can be entered via the free Crimson software package. The GTM also
accepts two, or three-wire, 100 Ohm platinum RTDs to monitor tank
temperature. The trending feature allows an operator to look at a history of the
temperature, similar to that of a chart-recorder.
The unit comes standard with Ethernet and RS485 ports, which allow
unlimited connection possibilities to PCs, PLCs, and SCADA systems. As an
option, Red Lion can configure the communications protocols, addresses, and
memory map prior to shipment. The built-in web server allows users to view and
control the GTM from any networked PC via standard web browser.
All standard programming is done via the bright 10.4" touchscreen. Critical
parameters are protected by a programmable password, while often-changed
values are accessible via an easy to use menu.
Enclosed in a stainless steel Hoffman Concept
for the food and beverage industry, the GTM is suitable for use in demanding
applications such as those found in the dairy and beverage markets.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially harmful to
persons or equipment in the event of a fault to the controller.
CAUTION: Read complete
instructions prior to installation
and operation of the unit.
