Udførte Projekter i ind- og udland:
From NERI, Jens Larsen has used RCM9 Recording Meters within inspection around mussel rafts, placed in the North of Spain. Net current direction and speed were measured by RCM9 units.
From 1999 NERI (DMU) also has placed 1-3 RCM9 units at strategic places within Limfjorden, an inlet in the north of Jutland. Measurement here has been done nearly uninterrupted.
Location: Spain and Denmark:
Sensors: Current Speed/Direction, Temperature, Conductivity, Turbidity, Pressure
Data Handling: off-line through DSU Reader and 5059 Data Reading Program

|Rain Gauge together
with Hobo Datalogger
For environmental projects we have delivered several Semi-Pro Rain Gauges with Hobo H07-002-04 Event Logger for detecting amount of precipitation. The Semi-pro Rain Gauge has 2 reed switches with 1 normally closed contact and 1 with normally open. The Rain Gauges can be delivered calibrated for 0,20 mm per pulse output or 0,25 mm per pulse.
Also a Sampler Interface has been included a delivery to a customer, who wanted the Rain Gauge as master for starting a Water Sampler Unit, when it starts raining.
Location: Denmark and abroad
Sensors: Semi-Pro Rain Gauge
Data Handling: off-line through PC an BoxCar Pro software
|Air Flow and Air Direction Sensors
For a tunnel project at Faroe-Islands (Hovstunnel, between Hov and ravik) we have delivered a 3343 Air Flow Sensor and 3343 Air Direction Sensor from Aanderaa Data Instruments, together with 3429 Signal Converters for 4-20 mA output signals. These sensors are designed for control of ventilation fans in road tunnels, when the natural draught or wind is insufficient for proper ventilation. A 3017 Display Unit with engineering units and 4-20 mA output signals is also suitable as a local display and as output for connected PLC.
Location: The Faroe-Islands
System: AADI Air Flow and Direction Sensor with 4-20 mA Signal converters
Sensors: Air Flow and Air Direction
Data Handling: 4-20 mA signals to PLC
|Forest and Landscape
For a daily measurement of wind speed, wind direction, air temperature, humidity, solar radiation and rain, 1 system with a 10m mast has been delivered for monitoring weather parameters into an open landscape. Another system with a 4m mast has been placed into a forest, close to the first system. Both system are solar panel powered with NRG Symphonie Datalogger and iPack as data collector and transmitter by GSM to the Receiver. All collected data is transmitted once a day as e-mail. An ED-Cup Anemometer with NRG interface has been delivered for the most precise measurement of wind speed.
Location: Als - Denmark
System: NRG, Vaisala, Licor, ED
Sensors: Wind speed, Direction, Temperature, Humidity, Solar, Rain
Data Handling: On-line by GSM and e-mail
