| The Andra Marine Guard WLR is a rugged and powerful tide level recorder developed based on the Marine Guard platform.It can be used for self-contained measurement of tide level and temperature.At the same time, the instrument can also be used as a platform to expand to add other measurement parameters (such as CTD, sea current, dissolved oxygen, turbidity).At the same time, both marine and freshwater environmental applications are taken into account. |

| SeaGuard WLR uses a silicon pressure 5217 probe to measure the static pressure of the hydrobody, and the pressure measurement is obtained by temperature compensation of seawater measurement data through advanced digital signal processor. |

| The SeaGuard WLR measurement works by fixed installation, or installation on shallow water seabed, or installed on a fixed structure in the water. It is typically used for measurement of port waves and tides, shipping weather forecasts, climate research and other quantities.The measurement of the tide is the average of the hydrostatic pressure over a period of time (10 seconds to 8 minutes, set by the user), with measurement intervals ranging from 2 seconds to 2 hours. |

| sea guard W LRThe output parameters are tidal pressure, tidal level, pressure and temperature.The instrument directly calculates the tidal level data based on the fixed atmospheric pressure value and salinity value selected by the user.If the user has real air pressure and salinity data, it can also be corrected through post-processing methods.Tidal pressure is the average value of static pressure of water over a period of time. |
