Micro-Diver

Micro-Diver

The Micro-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 18mm in diameter, the Micro Diver incorporates an internal pressure sensor that measures hydrostatic pressure above the sensor diaphragm to calculate total water depth.

The Micro-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

Micro-Diver Ranges

The Micro-Diver is available in the following ranges:

• 10m
• 20m
• 50m
• 100m

Datlogging Capacity

The Micro-Diver can store an up to 48,000 data-points including:

• Date
• Time
• Depth
• Pressure
• Temperature

The Micro-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

• 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. MDC Cable

 

Baro-Diver 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.

Diver Reader unit

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

Simply insert the Diver into a USB Reader 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 (2022) must be installed to be able to communicate with the Diver.

Telemetry Options

When deployed as a long-term long term uninterrupted, real time water level logger, the Micro Diver can be coupled with an Eijkelkamp GDT-S Prime (4G modem) enabling remote data transmission (email) over the 4G Network.

Using a user supplied SIM Card, the Eijkelkamp GDT-S Prime transmits water level data (via email) anywhere in the world where there is 4G internet coverage.

Transmitted parameters include:

• Date
• Time
• Depth
• Pressure
• Temperature
• Atmospheric Pressure

The GDT-S Prime is designed to be placed within a 50mm monitoring well and incorporates an external antenna, allowing data to be communicated on a daily basis, without operators having to go into the field!

Diver Software 2022

Setup monitoring projects and identify fieldwork tasks such as a site visit sequence, collection of Diver data and deployment of Divers using Diver Software (2022).

Diver Software (2022) 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.
