Product Introduction

The LSH10-1A handheld ultrasonic Doppler flowmeter is a portable, lightweight, and easy-to-operate instrument for flow measurement. It is an ultrasonic flowmeter designed based on the principle of the “Doppler effect.” Using ultrasonic technology, it detects flow velocity with the measurement point located at the front of the device, ensuring that the flow field remains undisturbed. The instrument boasts high measurement accuracy, linear flow characteristics, and the ability to measure both instantaneous and average flow velocities. It features no rotating parts, making it resistant to clogging by sediment and entanglement by aquatic vegetation; its probe is robust and durable.

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. With no mechanical rotating parts, this device is free from issues such as silt blockage or entanglement by aquatic plants and debris. It is ideally suited for river measurements in environments characterized by high concentrations of suspended sediments, abundant floating vegetation, and extremely harsh ice conditions.

Feature Introduction

1. The mini-sized handheld unit is easy for users to carry and use for measurement and observation;

2. The large-screen LCD features a continuous backlight function;

3. Built-in full clock for convenient time calibration and inquiry by users;

4. Equipped with data reading software to enable data storage, printing, and output functions;

5. Real-time display of instantaneous flow rate and cumulative flow rate; measurement modes include automatic measurement and manual measurement, catering to different application scenarios.
