It is used to automatically fill a water tank from a pump located a few kilometres away. It consists of two main parts, the transmitter in the tank and the receiver in the pumping station panel. The transmitter detects the level of the tank and sends start or stop commands to the pump accordingly. This eliminates the need for constant monitoring of the tank level. The big advantage of the PT680 is that the commands are transmitted wirelessly, so the installation costs are significantly reduced. The range of the system is up to 3km, with good line of sight. The commands are sent in absolute encryption and are impossible to break
The system is also available as:
PT680DSET when the tank is filled simultaneously by two pump stations.
PT680SSET when there is no mains voltage in the tank, (the power supply is replaced by a solar panel – charger – battery assembly).
PT680DSSET when the tank is filled simultaneously by two pump stations and there is no mains voltage.
PT680HSET when the level control in the tank must be done by means of hanging electrodes.
