The PT690 wireless system is used for automating the filling of a water tank by a water pump situated a few hundred meters away. It consists of two main components, a transmitter installed in the tank and a receiver installed in the pump's electrical panel. The transmitter monitors the level of the water tank and accordingly emits START or STOP messages to the receiver situated in the water pump This eliminates the need for constant monitoring of the tank level by the user. The great advantage of using a PT690 lies in that commands from the tank to the pump are wirelessly emitted, thereby reducing significantly the cost of installation. The range of the system exceeds 500 meters depending on propagation conditions (within line of sight). The commands are emitted fully encoded to ensure security. The system is indicated for installations where the water tank lies at a small distance from the water pump but the use of a cable for their connection is not possible.
