Digital Water Level Recorder (DWLR)

Digital Water Level Recorder (DWLR) is used to measure the level of ground water and surface water continuously on a real-time basis. It is supplied with battery, could work without manual control. The transmitter could record level or pressure change continuously. By setting proper data collection interval, the transmitter could record from several days to several years. Very low power consumption is another advantage
