Water level Logger
VLL-999 Recording Transmitter is able to be widely used in petroleum, chemi-industry, power station, water conservancy, city flood control and city water supply and drainage, etc. It is supplied by 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 advantages, one AA baterry 3.6V/2400mAh could work many years continuously. VLL-999 has an absolute pressure sensor inside, to measure lower level, please be careful for atmosphere change. We suggest to install a barameter or another VLL-999 Recording Transmitter to record air pressure. And then calculate two pressure difference of two instruments by computer, that is the final level value; Please pay attention that get VLL-999 back from the measurement point, then remove end cap and read record through data interface.
