Signature55 Long-range Ultrasonic Flow Direction and Velocity Meter ADCP
Signature55
A multi-layer flow direction and velocity meter with a measurement range of 1 km! Compact design, low power consumption, and equipped with dual frequencies (55/75 kHz)!
Signature55 is a multi-layer current velocity profiler with a pressure resistance equivalent to a water depth of 1500m and a measurement range of 1000m. Equipped with Nortek's new AD2CP platform, it achieves efficient observation mode control and low power consumption. Utilizing proprietary broadband signal processing, it enables reliable and high-precision data acquisition. Additionally, the design has been revamped to be compact and facilitate easy handling in the field. With the newly designed transducer, it performs the work of two devices in one. It can operate at two frequencies (55/75kHz), allowing for both extensive spatial measurements and high-resolution measurements (dense measurements in the depth direction) with a single unit. By using an AHRS (Attitude and Heading Reference System, optional), it corrects the displacement of the measurement position (cell position) in real-time due to the device's motion. This allows for more accurate current velocity measurements even in environments with significant motion, such as when mounted on a surface buoy.

basic information
Features: Equipped with the new Nortek AD2CP platform, it can automatically switch between multiple observation modes with a single unit (patented). The settings for the observation modes can be easily configured via software. For example, while performing flow direction and velocity profiling at a measurement distance of 1000m in 55kHz frequency mode, it is possible to obtain spatially high-resolution flow direction and velocity data at a shorter distance (600m) using a frequency of 75kHz. It can record compass data at a high sampling rate, eliminating the need for correction work before observation. Corrections can be made during the post-processing of data after equipment retrieval (using software, etc.). With Ethernet communication capabilities, even vast amounts of data, reaching several GB, can be transferred to a PC in a short time (approximately 6 minutes per GB). This reduces the time from retrieval to reinsertion. Others: - Equipped with an LED lamp for operation confirmation - Improved access to the battery due to the new rear-end design - Both Serial and Ethernet communication are standard features - Easy to mount on Nortek flat buoys (please inquire separately) - Battery case shapes: 3 types (no battery, 1 battery, 2 batteries)
