Starflow
Systems流速、水深
STARFLOW, a complete hydrographic data collection system, is a unique combination of water velocity, depth, flow and temperature instruments integrated with a fully featured 120K STARLOG MicroLogger.
The system comes complete with Version 3 for STARFLOW Software, a comprehensive user's manual and default schemes. Also included are 15 metres of vented cable, a drying tube and an adaptor cable for computer and battery connection.
Model 6705 Expanding Band Kits are available for mounting the STARFLOW instrument in various round or ovoid pipes.
流速、水深探測器
The Ultrasonic Doppler Instrument is a compact, easy to use system for measuring the velocity and depth of water in rivers and streams, open drainage channels and large pipes.
It is suitable for use in a wide range of water qualities ranging from sewerage and waste water to clean streams, potable water, and even sea water. The instrument measures forward and reverse flow conditions and may be programmed to compute Flow Rate and Total Flow in pipes and open channels.
The Model 6526B consists of a combination of an ultrasonic transducer assembly (profiled to reduce flow disturbance) and signal processing electronics. It is designed to be placed at (or near) the bottom of the water channel for "upward looking" measurement. A single cable connects the instrument to a 12V dc power source.
Water velocity is measured by the ultrasonic doppler principle which relies on suspended particles or small air bubbles in the water to reflect the ultrasonic detector signal. The instrument will not operate in very clean, "de-gassed" water. Water depth is gauged by a hydrostatic pressure sensor, referenced to atomospheric pressure through the vented power and signal cable.
Water temperature is also being measured. It is used to adjust for the change
in velocity due to speed of sound and is also available for logging.
