The MIDAS WLR is a precision water level recorder, designed for use in both autonomous and real time deployments. Fitted with a 0.01% accuracy pressure sensor and accurate PRT temperature sensor as standard, the MIDAS WLR features a variety of operating modes from rapid 8Hz continuous sampling to power saving burst modes for long term monitoring. The instrument is available in either shallow water Acetal or deep water Titanium versions, and is suitable for fixed or in-line mooring, with a variety of communications options built in.
Sensors
The MIDAS WLR comes with a choice of pressure sensor ranges to suit the depth requirement of the operator. The sensor used is a revolutionary piezo-resistive cell with internal temperature compensation, giving the accuracy and resolution levels normally associated with a resonant quartz sensor, but with increased durability, stability and recalibration intervals.
