Water Level Sensors

TD-Diver

The TD-Diver is a submersible water level logger designed for long term uninterrupted, real time water level monitoring.

Manufactured from 316L Stainless Steel and measuring just 22mm in diameter, the TD-Diver incorporates an internal pressure sensor that measures hydrostatic pressure above the sensor diaphragm to calculate total water depth.

The TD-Diver is ideal for various applications including:

• Long term water level monitoring
• Groundwater monitoring
• Surface water monitoring
• Network automation monitoring
• Watershed, drainage basin and recharge areas
• Stream gauging, lake levels and reservoirs
• Wetlands and storm water run off monitoring

TD-Diver Ranges

The TD-Diver is available in the following ranges:

• 10m
• 20m
• 50m
• 100m

Datlogging Capacity

The TD-Diver can store an impressive 72,000 data-points including:

• Date
• Time
• Depth
• Pressure
• Temperature

The TD-Diver incorporates the following sample methods:

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

Cable options

Various Diver communication cable lengths are available:

• 1m MDC data cable
• 2m MDC data cable
• 3m MDC data cable
• 4m MDC data cable
• 5m MDC data cable
• 7m MDC data cable
• 10m MDC data cable
• 15m MDC data cable
• 20m MDC data cable
• 30m MDC data cable
• 40m MDC data cable
• 50m MDC data cable
• 60m MDC data cable
• 80m MDC data cable
• 100m MDC data cable
• 150m MDC data cable
• 200m MDC data cable
• 250m MDC data cable
• 300m MDC data cable

Divers can also be deployed using Stainless Steel suspension cables.

Atmospheric Pressure Compensation

To compensate Diver data for atmospheric pressure, the Diver range is complimented by an optional Baro-Diver.

The Baro-Diver records atmospheric pressure & temperature data, at predetermined intervals, which can be combined with Diver data.

Data Download Options

Logged data can be downloaded easily using the Diver-USB Reader Unit.

Simply insert the Diver into a USB Reading Unit and connect using the free Diver Office software.  Once connected the Diver can be programmed, settings can be changed and or data can be read/downloaded.

The Diver-USB Reader Unit connects to a USB port of a PC, Laptop and/or Tablet.

Note: Diver Software must be installed to be able to communicate with the Diver.

ROAK

The Diver data logger integrates with Eijkelkamps ROAK software to provide a streamlined solution for groundwater monitoring. Sensor data can be transferred to the cloud based ROAK platform, giving users access to current and historical information through custom dashboards, reports and alerts.

• View groundwater levels and trends in near real time
• Create customised dashboards, reports and automated alerts
• Reduce manual measurements while improving data access and decision making.

Download the ROAK app to read out a Diver water level logger in the field.

Diver Software

Setup monitoring projects and identify fieldwork tasks such as a site visit sequence, collection of Diver data and deployment of Divers using Diver Software.

Diver Software consists of two applications:

• Diver Office
• Diver Field

Use Diver Field to carry out fieldwork and download Diver data.

Use Diver Office to merge time series, barometrically compensate Diver data & convert into water levels, visualize data including manual measurements and export data into MON, CSV or XLSX files for use in third-party applications.
