Starflow Ultrasonic Doppler Instrument

Description

Starflow Ultrasonic Doppler Instrument

Brand : Unidata – Australia

OVERVIEW

Unidata 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 sewage and wastewater to clean streams, potable water and even sea water.

The instrument measures forward and reverse flow conditions and may be programmed to computer flow rate and total flow in pipes and open channels.

The ultrasonic transducer assembly is profiled to reduce flow disturbance. It is designed to be placed at (or near) the bottom of the water channel for upstream 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, degassed water. Water depth is gauged by a hydrostatic pressure sensor, referenced to atmospheric pressure through the vented power and signal cable.

Two version are available, depending on the requirements:

Model	Depth	Resolution
6526H-21	0 to 2m	1mm for 0-1m 2mm for 1 to 2m
6526H-51	0 to 5m	2.5mm for 0 to 2.5m 5mm for 2.5 to 5m
