About Us

Nortek AS is a scientific instrumentation company that develops and distributes water velocity instruments. Our products are based on the acoustic Doppler principle and span from single point turbulence sensors to long range current profilers. Our customers are scientists, research institutions, and consulting engineers, all with demanding applications requiring state-of-the-art instrumentation that is reliable and easy to use.

Our main office is about 15 km south of Oslo, Norway and this is where we do  development, product assembly and testing. In addition, we have subsidiaries in the US, UK, China, and the Netherlands, each with technical staff.  In other areas, our products are distributed by regional representatives. 

We currently ship close to 1000 instruments per year and our instruments are in use in more than 75 countries around the world.

Our History

During the period 1996-1999, Nortek and SonTek operated under a mutual agreement whereby Nortek did business primarily in Europe and Asia and SonTek did business primarily in North and South America. Today, there is no formal or informal relationship between the two companies, nor are there any common elements in the respective hardware and software. Nortek operates in all countries but development and manufacturing is still based in Norway.

These provide sales, support, and services. The organization has about 60 full time employees and more than 15 have advanced degrees.

The hardware, firmware, and software that forms the basis for the various product lines have been developed by engineers still employed by the company. We expect this situation to continue, although we see an increasing trend also in development to outsource development tasks that are better and faster done by external consultants.

Since the start, Nortek has enjoyed an annual revenue growth of 20-25% per year. The annual revenue of Nortek AS for the first time hit US$ 10 mill in 2006.

Our Products

Image

Nortek has a versatile product range and it can be divided into several groups, each with separate applications.

Current Profilers

Our Current profilers measure current speed and direction in multiple layers throughout the water column. Nortek makes current profilers with ranges from a few cm in 'High Resolution (HR)' mode to several hundred meters. Our current profilers are also used as operational vessel mounted systems. Shallow water current profilers can both measure the currents and the wave height / direction for engineering applications.

 

Current Meters

Current meters measure the water current at only one level. Current meters are simple to use and appropriate when only one point is required, if price is important, or to cover great depths on mooring lines. The Aquadopp current meter is small in size while extremely powerful as a sampling system.

Velocimeters      

Velocimeters belong to a special class of high-resolution 3D instruments used to study rapid velocity fluctuations in the laboratory or in the ocean. These instruments use focused beams to measure with high sampling rates in a small point.

 

Wave Systems

Wave systems measure both wave height and direction, in addition to current profiles. As opposed to surface wave buoys Nortek's wave sensors are out of harms way, and due to this they are ideal for areas with ship traffic or fishing activity. The wave systems are mounted on the bottom, on a frame, or on a subsurface buoy.

 

Vessel Mounted Current Profilers

A current profiler that is mounted to a ship can measure the current profile while the ship is moving. Ship motion is corrected for either by using bottom tracking firmware that measures the motion over ground directly, or by using input from the ships gyro and a GPS receiver. Nortek's vessel-mounted software takes care of the data correction, and presents the corrected current profiles graphically.

FEATURED PRODUCTS

Signature55

The first instrument in the Nortek Signature Series product line, the Signature55, employs AD2CP technology to extend the range of the Nortek brand of acoustic Doppler current profilers to as far as 1000 meters. This 55/75 kHz dual frequency, true broadband instrument brings to market a host of features and benefits carefully developed around the needs of the scientists and engineers working both within academia and in the offshore industry. ...

Signature 500/1000

Nortek's Signature1000 and Signature500 five-beam AD2CPs introduce a scientific powerhouse to the research community, providing an ideal platform for turbulence studies, while also fulfilling standard current profiling needs. Signature1000 and Signature500, two advanced five-beam current profiling systems, are made with the most demanding scientific user in mind. Built on the advanced AD2CP platform, Signature1000 and Signature500 are designed for ...

FEATURED SERVICES

Installation Services

Most of the tricky works is left to our industry partners around the world. Nortek does, however, offer assistance with the installation of vessel mounted systems.

FEATURED SOFTWARE

Nortek - Version QuickWave - Non-graphical, Wave Processing Software

QuickWave is Nortek's non-graphical, wave processing software. The software accepts raw data files from the Aquadopp current meter, Aquadopp Profiler, Vector, and The AWAC, and produces standard wave estimates of height, period, and direction.

Nortek - Version Storm - Graphical, Wave and Current Profile Data Processing Software

Storm is Nortek's graphical, wave and current profile data processing software. It accepts raw data files from the Nortek series of Aquadopp Profilers and the AWAC.

FEATURED TRAINING

Training

Nortek provides short courses and seminars for a variety of Doppler instruments, and any upcoming courses or seminars will be posted here. Typical topics which are covered during training are: Introduction to Doppler instruments. Velocimeters. Wave measurements. Instrument maintenance. Online application. Special arrangements can be made for short courses; this is particluar true for vessel mounted systems. Contact Nortek to discuss what we can do to ...
