MIDAS WLR is a high-precision water level, tide gauges, which can work automatically self-contained, real-time online can work. 
System Configuration 0.01% range PRT precision pressure sensor and a temperature sensor. Either fixed-point mooring installation can be installed.

Data Collection 

MIDAS WLR sampling frequencies up to 8Hz, and a variety of sample acquisition modes such as continuous mining, external trigger mode and bursting mode. A typical pattern is bursting mode, in this mode, the user can set the data time (single-point sampling data set to 60 seconds range), collection interval time can be set once for one minute to one day. All recorded data can be sampled, but also to record only the mean with standard deviation, generally use either the user selects 40 seconds each acquisition calculate the mean, in order to filter out the impact of waves on tidal measurements. Valeport acquisition design allows the system to be distributed directly to the original pressure measurement value is automatically converted to the user's engineering units such as meters, feet and so on.
