ADCP 300kHz Phased Array

Ocean-ADCP-300-PA5

The ADCP 300 kHz PA5 pairs a five-beam planar phased-array transducer with a titanium pressure housing, delivering a high-performance direct-reading ADCP for coastal, shelf and deep-water monitoring.

Overview

A planar phased array with electronic beam steering produces a clean measurement profile without a protruding piston transducer. The design supports a 30° beam angle, 3.5° beamwidth and 1 mm/s velocity resolution.

Key Features

120/160m Profiling Range

Broadband and narrowband modes extend current profiling across coastal, shelf and deeper observation environments.

Precision velocity data

±0.5% ±5 mm/s accuracy, 1 mm/s resolution and ±2° direction accuracy provide dependable profile measurements.

compact housing design

The shell size is only Φ112 × 126, compact and low-interference, suitable for unmanned platform expansion for flow measurement scenarios

Low-power endurance

Average consumption of ≤6 W from a 20–50 V supply supports extended operation; an external battery is optional.

Built for depth

Titanium alloy construction is available with 1,000 m, 3,000 m or 6,000 m depth ratings for varied deployment needs.

Integrated storage and sensors

64 GB internal storage, RS-232/RS-422 communication, and standard temperature, pressure, tilt and compass sensors.

Applications

Long range without excess complexity

Up to 160 m in narrowband mode

Select broadband for 120 m profiling or narrowband for 160 m reach, with 1–255 cells and cell sizes from 1 m to 8 m.

Velocity and direction you can resolve

1 mm/s velocity resolution, ±0.5% ±5 mm/s accuracy and ±2° current direction accuracy support detailed flow analysis.

Three depth ratings, one compact body

Choose a 1,000 m, 3,000 m or 6,000 m titanium housing. At ≤2.28 kg and Ø112 × 126 mm, the PA5 integrates easily.

Frequently Asked Questions

Quick answers about profiling range, configuration and integration for the Ocean-ADCP-300-PA5.

How is profiling range different from depth rating?

Profiling range is the distance over which the ADCP measures the current profile. Depth rating is the pressure rating of the housing, available in 1,000 m, 3,000 m and 6,000 m versions.

What power source does it require?

The direct-reading instrument accepts 20–50 V and consumes ≤6 W on average. An external battery and an AC/DC power converter are available as options.

Which sensors are integrated as standard?

Temperature, pressure, roll/pitch and compass sensors are included as standard. Bottom tracking is available as an option.
