Japan Society of Oceanography 2023 Autumn Conference

A new ADCP equipped with a scientific fish finder sensor (frequency 70~120 kHz)! It can measure both flow and biomass with a single device.

The Signature100 is a completely new ADCP equipped with both a flow direction and velocity profiler (with a measurement range of 400m) and a scientific fish finder sensor (echo sounder). For example, when focusing on the relationship between the behavior of fish and microorganisms (such as krill) in the ecosystem and ocean currents, it was previously necessary to measure acoustic reflections (echograms) and flow direction and velocity data with separate devices. The Signature100 allows for the acquisition of both types of data with just one device. Specifications of the scientific fish finder sensor: Beam width: 15° (70 kHz), 8.7° (120 kHz) Monochromatic pulse: 70kHz, 90kHz, 120kHz Frequency chirping: center frequency 100kHz (BW50%, 70kHz–120kHz) Vertical data spatial resolution: 0.375–4m (1800 data points) Pulse length: 0.5–6ms Resolution: 0.01dB Dynamic range: 130dB

In addition to conventional multi-layer flow direction and velocity measurement, it is equipped with various measurement options. It can accommodate various observation purposes such as waves, turbulence, sea ice, and echograms, all in one device.

The Signature1000 and Signature500 are lightweight, compact, and multifunctional acoustic Doppler current profilers (ADCP) designed to meet various measurement needs in coastal areas. Functions such as wave, turbulence, sea ice, and echogram measurements can be freely selected and added later. Echograms can be obtained by using a transducer positioned at the fifth center as an echo sounder, allowing for high-resolution measurement of underwater biomass. With the new AD2CP platform, it is now possible to simultaneously execute multiple measurement functions (patented technology), enabling the acquisition of high-density information in a short period. They are also optimal tools for turbulence observation. Regarding sampling frequency, the Signature1000 has a maximum of 16 Hz, while the Signature500 has a maximum of 8 Hz. It has become possible to analyze parts of the turbulence spectrum that were previously difficult to measure.

A lightweight, compact, and simple-shaped ultrasonic flow direction and velocity profiler. It also features pressure wave measurement (PUV) capabilities, catering to various measurement applications.

The Aquadopp Profiler is a highly versatile ultrasonic Doppler current profiler (ADCP). There are four types in the lineup depending on the measurement range (distance). It is the ideal ADCP for those who want to simply conduct multi-layer current and velocity observations. In particular, it allows for wave measurements using a pressure gauge to be performed between current and velocity measurements, making it a series with high cost performance. The model equipped with the Z-Cell function can emit sound waves horizontally from the sensor head, allowing for the measurement of flow around the instrument. This feature enables the measurement of flow very close to the instrument, which was difficult with conventional ADCPs. The measurement range is from less than 1 m to over 85 m. The measurement range is determined by the acoustic frequency of each model. (Model name: Maximum measurement range) - Aquadopp Profiler 2MHz: 20m - Aquadopp Profiler 1MHz: 25m (including Z-Cell) - Aquadopp Profiler 600kHz: 40m (including Z-Cell) - Aquadopp Profiler 400kHz: 90m

A super small current velocity profiler (ADCP) for shallow waters equipped with numerous new features!

We have streamlined the complex mechanisms involved in handling flow velocity sensors and revamped the design and functionality to enable measurements with as few steps as possible. For the first time at Nortek, data quality verification and processing will be performed in the cloud (eliminating the need for dedicated analysis software). Japanese language support is available. [Easy Operation] Automatically sets three water depths and continues measurements while tracking water level changes. Users do not need to specify the measurement depths. [No Cables Required] Non-contact communication (for Eco and disconnection device settings) *Uses the built-in Bluetooth communication function of a smartphone or PC. [No Battery Replacement Needed] Uses a built-in rechargeable battery with non-contact charging. [Simple Setup] Settings can be configured via a web page on the internet or a smartphone app (iPhone and Android compatible apps are available: Nortek Eco; the web page can be accessed via "Related Links"). [Features, etc.] - Low water depth compatibility: Measurements can be taken from 30 cm above the device. - Number of measurement points (water depth, layers): 3 - Equipped with GNSS - Multi-color LED for operation confirmation *Installation is only upward. *Output data will be the horizontal flow velocity (east, west, south, north) at three water depths, but the measurements are three-dimensional flow velocities.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.
