Overview
Device Characteristics
The WESROC
®
RMS Industrial LTE 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 public cellular network and the internet to transport this
information.
Communication with the Host is always originated by the CTM, but is bi-directional once a
data session has been established. This 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 ISM 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 when local tank level
display is not needed.
By default, the CTM is configured to monitor the most common type of tanks, 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 (PDU).
Refer to the ‘WRMS Hydrostatic Sensor Interface Quick Installation Guide’ and the ‘WRMS
Dual Hydrostatic Sensor Kit Quick Installation Guide’ for installation of the additional
equipment associated a hydrostatic CTM.
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 to be
intrinsically safe for use in hazardous environments.
