RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc.

Overview
Device Characteristics
The WESROC
®
RMS Cellular Tank Monitor (CTM) is used to remotely monitor the level
of the contents of a tank. The tank level and additional event and status information are
reported to the WESROC
®
RMS Host System (Host) at scheduled intervals. In addition,
the CTM will report to the Host immediately to track tank events in real time. The CTM
uses the GSM cellular network and the internet to transport this information.
Communication with the Host is bi-directional which allows for remote configuration of
the CTM should the tank monitoring requirements change or in the event that the CTM
is moved to another site.
The CTM also provides a local tank level display capability. The CTM can be configured
to send short range radio data packets to a nearby WESROC
®
RMS Base Unit (Base
Unit). Once initialized to the CTM, the Base Unit will provide the customer with a local
display of tank level for up to eight tanks (depending on which Base Unit is used).
Installation
A basic CTM installation is easily performed in a few minutes by persons with a basic
understanding of the tank equipment to be monitored and of the CTM device itself.
Since the CTM is self-contained, the complete installation can be performed at the tank.
No access to the customer’s residence or place of business is required.
By default, the CTM is configured to monitor the most common type of tank, but may be
re-configured to monitor a wide variety of tank configurations. The CTM may be
remotely configured by the Host or may be configured on site by using the handheld
WESROC
®
RMS Portable Diagnostic Unit.
Power
The CTM is battery powered, and due to its low power design will provide many years of
remote monitoring before battery pack replacement is required. Battery pack
replacement may be performed at the tank as the CTM and battery pack are both
designed and certified to be intrinsically safe for use in hazardous environments.
