Product Introduction

The LSH10-1 ultrasonic Doppler flowmeter is an ultrasonic flowmeter made using the principle of ultrasonic "Doppler effect". It does not have rotating parts such as propellers or bearings, and uses ultrasonic technology to detect flow velocity without friction or inertia. The measurement point is located in front of the body, without damaging the flow field. It has high measurement accuracy, wide range, sensitive induction, linear flow measurement, is not afraid of sediment and floating debris, intuitive reading, easy operation, and is not easily damaged.

■ Performance characteristics

★ High measurement accuracy, wide range, capable of measuring weak current and strong current;

★ Sensitive induction, high resolution, not limited by startup flow rate;

Fast response speed, capable of measuring instantaneous flow velocity and average flow velocity;

★ Linear measurement, K and C values without calibration curve;

★ No mechanical rotating parts, no mud blockage or entanglement of water plants, debris, etc., most suitable for measuring in rivers with high suspended solids content and floating objects such as water plants.

■ Function Introduction

★ Large screen LCD display with continuous background light function;

The instrument cable can be directly loaded or suspended in two ways;

★ Built in large capacity data storage, accommodating up to 5000 sets of data;

★ Built in complete clock, convenient for users to calibrate and check time;

Equipped with data reading software to achieve data storage, printing, and output functions;

Real time display of flow rate and temperature values;

★ The measurement mode is divided into automatic measurement and manual measurement, meeting the needs of different occasions;

★ Measurement data can be remotely transmitted to up to five designated user terminals in real-time via GPRS mode.

The internal measurement mode of the instrument is designed in strict accordance with hydrological industry standards.
