General Acoustics offers a Calibration-free portable
Water Level and Wave Measuring System
The mobile Tide and Wave Gauge LOG_aLevel® interests
Dredgers and Surveyors
This
product is based on autonomous remote sensing via ultrasound
technology for water level monitoring, wave measurement, flood warning
and prediction, tide monitoring, reservoir control and environmental
monitoring. |

The
system is cost effective, robust, compact, highly flexible, easy to
install and maintenance free. Due to the narrow sound beam a mounting
near constructions and buildings is possible. Measurement distances
from 0,5 to 6 m (optional up to 10m) are possible
The
LOG_aLevel®
system
(Fig.1) can be located e.g. at a quay or a jetty to measure the level
and works with 12 V, 110/230 V power supply or a battery (> 12 h
continuous supply). The level data is provided via RS232 output and
can be delivered via licence-free radio transmission to a digital
display (Fig.2) on a dredger or survey vessel. The water level could
also be transmitted to a PC in the harbour office to display the level
data on the LOG_aLevel® Software which is included in the
basic package. Also a 1 GB data logger can be used to store the data. |

The
application to have an accurate water level on
the vessels is very interesting for dredgers and surveyors.
A
similar LOG_aLevel®
is used in the
Port
of Le Havre
to
support a dredger with the current water level during its working
time. Also the US Army Corps of Engineers in the San Francisco
District use Mobile LOG_aLevels to support their survey ships with
accurate water level. |
