Product details
I. Introduction to the Instrument
The LSH10-1P-600S horizontal acoustic Doppler current profiler is typically installed on shore walls or bridge piers. It can perform long-term, unattended measurements and is primarily used for monitoring river flow velocity and discharge, measuring flow velocity and discharge in large open channels, providing flood warnings, monitoring environmental handover sections, and supporting water diversion projects.
II. Product Features
1. Employs broadband technology for high precision and high resolution.
2. Install horizontally on the quay wall or bridge piers.
3. Standard built-in ultrasonic level meter, pressure level meter, and attitude sensor (roll, pitch)
4. Built-in indicator flow velocity algorithm, displaying flow velocity in a two-dimensional horizontal profile with layered visualization.
