FlowTracker Handheld ADV Expanded Description

- 1. Introduction
- 2. FlowTracker Technology
Offering laboratory precision
in a practical and easy-to-use design, the FlowTracker Handheld ADV (Acoustic Doppler
Velocimeter) goes where no current meter has gone before. Capable of measuring velocities
from 0.001 m/s (0.003 ft/s) to 4 m/s (13 ft/s), and in water as
shallow as 2 cm (~1 inch), the FlowTracker simply outperforms every other
hand-held current meter on the market.
Designed
with the field user in mind, the FlowTracker easily attaches to top-setting wading rods
and features an automatic discharge computation program that is based on USGS/ISO methods.
The FlowTracker is delivered "ready-to-go" from the factory, so gone are the
days of spin tests and other complicated instrument calibrations.
With a built-in recorder, battery, and RS-232
interface, the FlowTracker is flexible enough to be used either by the keypad display or
interfaced to an external data logger or personal computer.
SonTek's ADV technology has been well established for many years as the preferred
sensor for high-resolution, 3D water velocity measurements. This same technology has been
incorporated into the FlowTracker to provide the same ADV functionality from a simple
keypad/LCD interface, allowing rapid data collection and analysis in many natural stream
and open channel environments.
The FlowTracker collects a burst of data at user-selected measurement locations. The
burst length is adjustable, allowing you to record mean velocity over a defined averaging
period. A simple, menu-driven interface prompts you to enter your data collection
parameters.
The
FlowTracker uses acoustic Doppler technology to measure 2D or 3D flow in a small sampling
volume located a fixed distance (10 cm) from the probe. Sound generated by the
transmitter bounces off suspended particles in the water. This reflected sound returns to
the receivers, is averaged together by the processor, and results in water velocity
measurements that are recorded at a rate of once per second.
