Valeport Midas WLR: Water Level Recorder

Availability: Ex-Rental Sale, Rental, Sale

The Valeport Midas WLR is a precision water level recorder, designed for use in both autonomous, or real time deployments. Fitted with a 0.01% accuracy pressure sensor and accurate PRT temperature sensor as standard, the Valeport Midas WLR features a variety of operating modes from rapid 8 Hz continuous sampling to power saving burst modes for long term monitoring.


High accuracy data.

Long deployment times.

Wide choice of sampling regimes.

The sensor used is a revolutionary piezoresistive 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.

In-line or seabed deployment.


Pressure type: Temperature compensated piezo-resistive cell

Pressure ranges: 10, 20, 30, 50, 100, 300, 400 or 600 Bar

Temperature type: Titanium housed PRT

Temperature range: -5°C to +35°C

Electrical internal: 8 x C cells, 1.5 V alkaline or 3.6 V lithium


Ideal for autonomous and real time deployments

Designed for long or short-term deployments in offshore environments, or locations where a traditional shore-based tide gauge is impractical.
