No-contact measurement
Sits above the water and measures the echo returning from the surface—no submerged probe to place or retrieve.
Monitor smarter. Visit less.
Know your groundwater level.
Without going underground.
The Ground water level sensor (SSD009) turns every monitoring pipe into a connected source of insight—automatically measuring water depth and sending it to your phone and cloud dashboard.

One small sensor. A clearer water story.
Turn field visits into forward decisions.
Replace manual spot checks with a connected view of groundwater conditions. GWL sensor helps teams see change sooner, document trends and focus field time where it matters.
Data, delivered
Integrated Cellular LTE-M send measurements to the cloud, bringing remote sites into one accessible view.
Freedom from mains
A replaceable lithium battery makes the sensor practical for remote wells and sites without external power.

Review live values and historical data to spot movement, support reporting and make earlier interventions.
Simple by design
From echo to insight in three steps.
The clever part happens inside the sensor. Your team gets the result.
Acoustic

Send
The sensor generates an acoustic tone down the groundwater pipe.
Measure
The returning echo is analysed to calculate distance to the water surface.
Connect
The measurement travels over cellular connectivity for app and cloud access.

Frequently asked
Good questions.
Straight answers.
No. SSD009 measures from above the water surface using an
acoustic tone and its returning echo. It does not require a
submerged probe.
No. The unit runs from a replaceable 3.0 V lithium battery;
the product specification recommends a CR123A battery of
approximately 2800 mAh.
The integrated cellular modem supports Cellular LTE-M for
cloud transmission. Bluetooth Low Energy is also available for
local communication.
The dashboard provides current readings and battery status,
plus historical reporting by device, parameter and date range
for ongoing review and analysis.
Yes. One year of GWL Cloud portal service and one year of SIM
card service are included with your SSD009 purchase. Renewal
options after the included first year are confirmed with your
order.
