Remote pump from tank control system, 20km with solar charger

Used for the wireless and automatic filling of a water tank from a pump located at a distance of up to 20km (with good line of sight). It operates in the 169MHz frequency range, which is License-free, i.e. its use does not require a license from the end user. It consists of the PT930 transmitter, which is mounted on the tank and the PT912 receiver at the pump station panel. The PT930 transmitter detects the tank level and sends start or stop commands to the PT912 receiver on the pump. The transmitter is powered by a solar panel that ensures its autonomous operation. Commands from the tank are transmitted to the pump wirelessly, significantly reducing installation and maintenance costs. The commands sent between each transmitter and receiver are encoded and are not influenced or affected by any nearby system. The encoding of the transmitter and the receiver is done through DIP Switches. The system is also available with the capability of controlling two, three and four pumps from the same tank (types PT930DSET, PT930TSET, PT930QSET respectively).
