Digital Water Level Recorder (DWLR)
Digital Water Level Recorder (DWLR) is used to measure the level of groundwater and surface water continuously on a real-time basis. It is supplied with a battery and can work without manual control. The transmitter records level or pressure changes continuously. By setting a proper data collection interval, the transmitter can record from several days to several years. Very low power consumption is another advantage.
Model SLL99 was designed and developed by Swan under the Make In India (MII) program. We are the leading suppliers of DWLRs in India, with over 14,000+ installations. We have supplied under NHP & ABHY projects as well. SLL99 measures with high accuracy, stability, and durability.
