Product Overview

The MXS05DS ultrasonic Doppler flowmeter measures flow velocity by exploiting the acoustic Doppler effect. The CPU generates a fixed‑frequency pulse signal via a PWM controller, which is transmitted into the water through a transducer. When this pulse encounters suspended particles in the water, it produces an echo signal that is received by the ultrasonic Doppler flowmeter. As these suspended particles drift with the water flow, they induce a Doppler shift—i.e., a frequency difference between the echo signal and the transmitted signal. By measuring this Doppler frequency shift, the flow velocity at the corresponding measurement point can be determined.

Product Features

• High measurement accuracy, wide measurement range; capable of measuring both weak and strong currents.

• Highly sensitive, with high resolution, and not limited by the minimum flow velocity.

• It features fast response, enabling measurement of both instantaneous and average flow velocities.

• Measurement linearity, with no calibration curve. K, C value;

• With no mechanical rotating parts, it is free from issues such as sediment clogging or entanglement by aquatic vegetation and debris, making it ideally suited for river measurements in environments characterized by high suspended sediment loads, abundant floating vegetation, and extremely harsh ice‑covered conditions.
