Ultrasonic Doppler Flowmeter (Cableway Type)

1. Product Overview

The ultrasonic Doppler flowmeter is an ultrasonic flow measurement instrument based on the principle of the "Doppler effect." The cableway flow measurement system enables real-time monitoring of flow velocities at different depths and vertical lines within a cross-section, achieving unattended automatic flow measurement. By replacing the propeller flowmeter probe with an ultrasonic Doppler flowmeter probe in the existing cableway system, the velocity data measured by the ultrasonic Doppler flowmeter is converted into switch signals via a controller for use by the cableway system. The cableway system requires no modifications to output flow velocity data.

2. Performance Characteristics

High measurement accuracy and wide range, capable of measuring both weak and strong flows;

Sensitive detection, high resolution, unaffected by starting velocity limitations;

Fast response time, capable of measuring both instantaneous and average flow velocities;

Linear flow measurement, eliminating the need for K and C values in calibration curves;

No mechanical rotating parts, avoiding issues such as sediment blockage or entanglement by weeds and debris, which could affect accuracy.

Suitable for rivers with high sediment suspension, abundant floating weeds, and icy conditions.

3. Functional Features

Can be used in conjunction with cableway sounding weights to achieve multi-vertical line velocity measurement;

Equipped with an integrated lithium battery and a waterproof signal controller, which converts signals into switch signals for the cableway system;

The cableway system requires no modifications to output flow velocity data.
