TLS RF Wireless System Overview
Figure 2 illustrates an example TLS RF Wireless System installation. In the figure only one tank is shown, but
each tank being monitored by a Mag probe would require a battery pack/transmitter pair. The repeater
component may be required if the system receiver, mounted on building’s outside wall, has difficulty receiving
signals from any of the transmitters.
