WESROC Residential LTE Cellular Tank Monitor - Operation Manual

Overview
Device Characteristics
The WESROC Residential LTE Cellular Tank Monitor (RTM) 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 Host system (Host) at scheduled intervals. In
addition, the RTM will report to the Host immediately to track tank events in real time. The
RTM uses the cellular data network and the internet to transport this information.
Communication with the Host is always originated by the RTM, but is bi-directional once a
data session has been established. This allows for remote configuration of the RTM should
the tank monitoring requirements change or in the event that the RTM is moved to another
site.
The RTM can also provide a local tank level display capability. The RTM can be configured
to send radio data packets to a nearby WESROC Base Unit (Base Unit). Once initialized to
the RTM, 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 RTM installation is easily performed in a few minutes by persons with a basic
understanding of the tank equipment to be monitored and of the RTM device itself. Since
the RTM 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 RTM is configured to monitor the most common type of tanks, but may be
re-configured to monitor a wide variety of tank configurations. The RTM may be remotely
configured by the Host, or may be configured on site by using a handheld WESROC
Portable Diagnostic Unit (PDU).
Power
The RTM is battery powered, and due to its low power design will provide many years of
monitoring before battery replacement is required. The battery may be replaced in the field
once the RTM has been moved to a non-hazardous location.
