Remote pump from tank control system, 5km with float switch

Used for the wireless and automatic filling of a water tank from a pump located at a distance of up to 5km (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 PT980 transmitter, which is mounted on the tank and the PT912 receiver at the pump station panel. The PT980 transmitter detects the tank level and sends start or stop commands to the PT912 receiver at the pump. 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 pumps from the same tank (type PT980DSET) as well as PT980ESET when the level control in the tank must be done by hanging electrodes.
