Other ranges and cable lengths on request. Use of these modules allows tidal data to be telemetered in real time. The modules have been designed to be simple to install, have high immunity to background radio interference and have very low battery power drain. A range of modules offering differing facilities, frequencies and power outputs are available to suit most installations and budgets. Hydrosphere will be pleased to discuss individual installations if required.
All transmitters incorporate an internal battery power supply suitable for several months operation.
Low RF power modules also incorporate an internal antenna making installation extremely simple. Data may be displayed within a PC environment or by using a stand alone receiver display unit. Received data are available at three minute updates, twenty four hours a day. Data are presented in engineering units and in graphical format. Receiver display units are also able to drive remote LCD read outs of tide height over hundreds of metres of cable.
