Installation
Mounting Location
The WESROC Residential LTE Cellular Tank Monitor (RTM) is designed to be installed
directly on the tank to be monitored. The RTM is connected to the tank gauge by the tank
level sensor and sensor cable. The RTM itself may be attached to the tank with the
supplied mounting magnet. The RTM may also be located a few feet away from the tank if
necessary to improve cellular reception. If needed, versions of the RTM are available with
a longer sensor cable to facilitate mounting the RTM further away from the tank.
Tank Gauge
The standard RTM is equipped with a hall-effect based tank level sensor. This sensor is
designed to be snapped into a remote ready tank gauge dial. The sensor and dial are part
of the R3D dial and sensor system manufactured by Rochester Gauges. R3D dials are
available for a wide variety of tank and gauge types. The RTM is configurable to work
correctly with all available dial types.
Cellular Signal
The RTM must be installed in a location served by 4G LTE (Long Term Evolution) cellular
service. Models MT9104RTMA and MT9104RTMA1 are supported by AT&T and its
roaming partners. Models MT9104RTMR and MT9104RTMR1 are supported by Rogers
Wireless (Canada) and its roaming partners. Model MT9104RTMV1 is supported by
Verizon and its roaming partners.
The RTM has a robust cellular sub-system, but there are limits to the capabilities of the
cellular network in general. As with most wireless technologies, cellular signal reception
can be affected by obstructions such trees, mountainous terrain, buildings, metal
structures, large vehicles parked nearby, etc. In addition, cellular signal reception will be
directly affected by the distance between the RTM and the nearest cell tower with LTE
cellular service.
The best signal reception will be achieved with a line of sight path between the RTM and
the cell tower. Obviously, this is rarely the case in the real world, but it should be kept in
mind when selecting a mounting location for the RTM. Elevation can also help; typically
performance will increase as the RTM is raised higher above the ground. The orientation
of the RTM itself will also affect performance. The RTM should be installed upright, and if
possible, with the sensor cable exit on the RTM enclosure pointed AWAY from the nearest
cell tower supporting LTE cellular service.
