Instrument Overview

The LSH10-1Q ultrasonic Doppler flowmeter is an ultrasonic flow-measuring instrument based on the principle of the “Doppler effect.” The cableway flow measurement system monitors, in real time, the flow velocities at various vertical lines and different depths across a cross-section, enabling unattended, automated flow measurement. By replacing the propeller-type flowmeter probe on the existing cableway system with an ultrasonic Doppler flowmeter probe, the flow velocity data obtained by the ultrasonic Doppler flowmeter can be converted into switch signals via a controller and fed back to the cableway system. No modifications are required to the cableway system itself, thus allowing seamless integration and output of flow velocity data.

Performance Features

1. High measurement accuracy and wide measurement range—capable of measuring both weak and strong currents;

2. Highly sensitive, with high resolution and不受 the limitation of starting flow rate;

3. Fast response speed—capable of measuring both instantaneous flow velocity and average flow velocity;

4. Linear measurement with no K or C values for the calibration curve;

5. It has no mechanical rotating parts, eliminating issues such as silt blockage or entanglement by aquatic plants and debris. It is ideally suited for river measurements in environments with high concentrations of suspended sediments, abundant floating vegetation, and extremely harsh conditions during ice periods.

Feature Introduction

1. It can be used in conjunction with cableway lead fish to perform multi-vertical-line velocity measurements.

2. It employs an integrated lithium battery and a waterproof signal controller, which converts the signals into switch signals for use by the cableway system.

3. The cableway system can output flow velocity data without any modifications.
