• SDI-12 communications
• LCD option available
This 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 newest model, the 6526H, includes a new velocity
algorithm. The ultrasonic transducer assembly is profiled to
reduce flow disturbance and signal electronics. 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.
