Water Level Sensors

Van Essen

CTD Diver

The CTD Diver is a submersible datalogger designed for long-term uninterrupted, real-time water level monitoring.  It autonomously measures pressure & temperature, both of which are logged within its internal memory.  The CTD Diver is ideal for ground & surface water level applications.

The CTD Diver is equipped with a four electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm.  There are two options for measuring conductivity, true or specific conductivity at 25 °C.

The CTD Diver can store 48,000 data-points including:

• Date
• Time
• Depth / Pressure
• Temperature
• Conductivity (mS/cm, μS/cm, S/m)

The CTD Diver incorporates the following sample methods:

• Fixed length intervals
• Event dependent
• Averaging
• Pumping test

When deployed for long term long-term uninterrupted, real-time water level monitoring, the CTD Diver can be coupled with the Eijkelkamp GDT-S Prime (4G modem) for remote email data transmission over the 4G Network.  Larger applications can be connected to the Eijkelkamp GDT-Multiple UMTS.

The CTD Diver is available in the following pressure ranges:

• 10m
• 20m
• 50m
• 100m

Readings can be compensated by barometric pressure using the Baro Diver.

Software for the CTD Diver is available as a free download from the Aqualab website as follows:
