Digital Correlation Transit Time Flow Meter
Ductus TT
The Ductus TT is a compact instrument incorporating the latest electronics and Digital Signal
Processing (DSP)
technologies, realizing high performance and easy operation. With the use of
high-speed micro-processor, the response time is as fast as 1s or less. The system is well suited
to most environments.
The Ductus TT combines Digital Signal Processing (DSP) with correlation detection methods. It
uses controlled signals, whose characteristics are imposed during the transmission phase
(duration, frequency, level). The reception is therefore based on the suitable filtering of these
characteristics, accounting for the perturbations brought by the environment. The frequency
modulated signals are processed on reception by correlating the received signal with a copy of the
expected signal. The use of this HydroVision's proprietary
Intelligent-Signal-Processing(ISP) results
in very accurate measurements of transit time with an excellent time resolution and a high
processing gain.
