Key features
What OceanWatcher measures and reports
Choose surface-mounted radar level monitoring or a submerged current-measurement configuration, with readings delivered through a VikMote GSM logger to Emiko.
Non-contact radar level sensing
WLM radar sensors are mounted above the water surface. The sensor and mounting arrangement are selected for the site; measurement specifications are confirmed with the equipment configuration.
Data sharing
Live water data can be published on your own website or sent directly to the Danish Meteorological Institute (DMI) through the Emiko EasyShare module.
Mounting matched to the sensor
WLM radar heads are installed above the water on a suitable fixed structure. The WCM 100 current sensor is submerged on a pole and mounting bracket at the harbor wall.
Marine grade hardware
Built from durable, marine grade materials for consistent performance in harsh weather and water conditions, with long service intervals.
Early warning alerts
Real time alerts on abnormal water levels help staff and vessels navigate changing conditions, and signal failures are reported automatically.
Graphs, logs, diagnostics
Emiko gives full access to live graphs, historical logs and device diagnostics, so long term water level trends can be analysed over time.
Grid or solar power
Runs on 24 V DC or 230 V AC, or on solar with a 60 W or 80 W panel and 20 Ah battery on the WLM 200 and WCM 100, for urban and remote locations alike.
How it works
How OceanWatcher measures level and current
The measurement method and installation change with the model. The common Emiko connection brings the readings into one operating view.
For WLM 100 and WLM 200, a radar head is fixed above the water and connected by cable to a VikMote GSM logger. The head measures the water surface without being submerged. The logger sends readings to the Emiko platform and supports status and fault monitoring.
WCM 100 uses a submerged acoustic Doppler sensor for current measurement. Its mounting, measurement area and any temperature option are specified separately from the above-water WLM installation. Choose the model from the required data and the power available at the site.

Product guide
Choosing a water level gauge for your harbor
OceanWatcher turns the water level at your dock into live, shareable data. This guide covers who the system is for, how to pick a model, and what to expect from installation to daily operation.
Who OceanWatcher is for
A water level gauge earns its keep wherever people make decisions based on the water: ports and harbors planning safe inbound and outbound operations, locks and waterways managing flow, and coastal sites that need early warning when levels turn abnormal. OceanWatcher provides water level monitoring, with WCM 100 adding current measurement and temperature options selected for the installation, so one product family covers basic level monitoring as well as advanced current measurement.
The readings serve two time horizons at once: real time alerts that help staff and vessels navigate changing conditions today, and historical logs that let you analyse long term water level trends over the years.
Choose the measurement method for the task
A WLM installation uses radar above the water for non-contact level monitoring. A WCM 100 installation uses a submerged acoustic Doppler sensor for current measurement. The current-measurement range listed for WCM 100 is not a radar level-sensing range.
Vikingegaarden confirms the sensor specification and mounting arrangement for the measurement required at your site. Operating status and fault alerts are available through the shared logger and Emiko connection.
Picking the right model
The choice between the three models comes down to power and data needs. The WLM 100 is the basic surface mounted level monitor for sites with grid access: it runs on 24 V DC or 230 V AC and carries a 2 Ah internal battery. The WLM 200 is made for hybrid or remote locations: it accepts 230 V AC or solar power, supports an optional 20 Ah battery, offers a 5 A at 24 V output for an external battery and can be fitted with a 60 W or 80 W solar panel. The WCM 100 is the submersible model that adds water current measurement with an acoustic Doppler sensor, measuring horizontally across 1.5 to 120 m in depth zones, with an optional external temperature sensor.
A simple rule of thumb: grid power and level data only, choose the WLM 100; no reliable power at the site, choose the WLM 200; current data required, choose the WCM 100. Mounting brackets and a protective cover are available as accessories for all of them.
Installation and commissioning
For WLM models, the radar head is mounted above the water on a suitable fixed structure and connected to the VikMote GSM logger. WCM 100 uses a pole and bracket arrangement with its current sensor underwater. Power, sensor options and service access are planned around the selected model.
Where weather is also part of the operating decision, the Cumulus port weather station provides complementary wind and weather observations. Both product families can deliver data to the Emiko platform.
Live data, alerts and sharing
Every reading lands in the Emiko platform, where the harbor gets live status, maps, graphs, alarms and reports for each connected gauge, plus historical logs and device diagnostics. Abnormal water levels and signal failures raise alerts automatically.
Through the EasyShare module you decide who else sees the data: publish live water levels on your own website or social media, share them with your customers, or send them directly to the Danish Meteorological Institute (DMI). One gauge on the dock can inform everyone who depends on the water.

Frequently asked questions about OceanWatcher
What does an OceanWatcher water level gauge measure?
The WLM 100 and WLM 200 use radar to monitor water level. The WCM 100 configuration also measures water current using an acoustic Doppler sensor. Temperature measurement and other options are agreed for the selected installation, and readings are available through the Emiko platform.
Where can OceanWatcher be installed?
WLM 100 and WLM 200 radar heads are mounted above the water on a suitable fixed dock, harbor structure or other support. The WCM 100 current sensor is submerged on a vertical pole fixed to a mounting bracket. Vikingegaarden helps confirm the location and arrangement for the required measurement.
Does OceanWatcher use radar for both level and current?
No. WLM water level monitoring uses non-contact radar above the water. WCM 100 current measurement uses an acoustic Doppler sensor below the surface. The two measurement tasks require different sensors and mounting arrangements.
What is the difference between WLM 100, WLM 200 and WCM 100?
WLM 100 is the basic surface mounted level monitor for sites with grid access (24 V DC or 230 V AC, 2 Ah internal battery). WLM 200 adds an optional 20 Ah battery, external battery support and a 60 W or 80 W solar option for remote sites. WCM 100 is submersible and also measures water current.
Does OceanWatcher support customisable data access?
Yes. Through the EasyShare module in Emiko you control which stakeholders can see the water condition data. Data can be published on your own website, on social media, shared with your customers or sent directly to the Danish Meteorological Institute (DMI).
What should be checked when specifying an OceanWatcher installation?
Confirm whether you need level, current and temperature data, then review the mounting location, power source, communications and data-sharing requirements. Measurement accuracy, operating limits and service requirements should be confirmed for the selected sensors and site.
Can a water level gauge run on solar power?
Yes. The WLM 200 and WCM 100 accept solar power with an optional 60 W or 80 W panel and a 20 Ah battery, and both provide a 5 A at 24 V output for an external battery. That makes them suitable for remote jetties and sites without grid access. The WLM 100 requires 24 V DC or 230 V AC grid power.
How does a harbor get early warning of abnormal water levels?
OceanWatcher sends its readings to the Emiko platform in real time, and alerts are raised on abnormal water levels and on signal failures. Staff see live graphs and alarms, and the same data can be published externally through EasyShare, so warnings reach everyone who depends on the water.
