Repeaters are fastened with a standard strut channel mounting system on any suitable structure close to the rim of a tank. The Repeater provides a communications link between Multi-Sensors on the tank's floating roof and the Base Station. Multiple Repeaters may form a mesh network covering several tanks and connected to a single Base Station. In addition to providing a communication bridge, the Repeater is also equipped with a GPS antenna and a barometric pressure and temperature sensors. The Repeater is designed to last for over 10 years without requiring battery changes.
